NIH SBIR Funding for Time-Sensitive Environmental Health and Disaster Research: What Startups Need to Know
Below is a brief summary. Please check the full solicitation before applying (link in resources section).
Quick Answer
NIH has flagged time-sensitive environmental health research as a current priority through a Highlighted Topic titled "Time-Sensitive Research Opportunities in Environmental Health Sciences" (posted August 10, 2026, active through August 10, 2028). This topic is not itself a funding opportunity, so small businesses cannot apply to it directly. Instead, a U.S. small business applies through the NIH Parent SBIR announcement, PA-27-100, and writes its research aims to match what the topic describes: capturing exposure and health data during the narrow window that follows a disaster or an emerging environmental threat. The next Parent SBIR deadline is September 5, 2026, which falls on a Saturday ahead of Labor Day and therefore moves to Tuesday, September 8, 2026. Phase I awards run up to roughly $323,090 and Phase II awards up to roughly $2,153,927 under current SBA guidelines, with several participating institutes offering higher caps.
What is the "Time-Sensitive Research Opportunities in Environmental Health Sciences" topic?
It is an NIH Highlighted Topic, which is a signal from a group of NIH Institutes, Centers, and Offices that they want to receive applications in a specific area of science. It is not a Notice of Funding Opportunity (NOFO), and it does not have its own application package, budget, or deadline. NIH is explicit on this point: applicants pursue the topic by applying through an appropriate NIH Parent Funding Announcement or another broad opportunity on Grants.gov.
The topic exists because disasters and emerging environmental threats create a short, often unpredictable window in which exposure and health data can be collected. Once that window closes, the scientific value is lost. NIH wants research that moves fast enough to capture that information and that lays the groundwork for later, longer-term analysis of how those exposures affect health. A strong application makes two things obvious: that the triggering event was genuinely unforeseen, and that the proposed study is both scientifically valuable and feasible inside that limited window.
For a small business, the practical takeaway is simple. If your technology or study can capture exposure, biospecimen, or health data quickly after a natural or human-made disaster, or in response to an emerging environmental public health threat inside the United States, this topic tells you that three parts of NIH are actively looking for that work right now. You reach them through the Parent SBIR.
How does a startup actually apply for this?
You apply through the NIH, CDC, and FDA Parent SBIR announcement, PA-27-100 ("Parent SBIR [R43/R44] Clinical Trial Optional"). This is the vehicle that turns the Highlighted Topic into a fundable application for a for-profit small business.
The workflow looks like this. You confirm your company is an eligible U.S. small business concern, you register in the required federal systems, you build your Phase I feasibility study (or a Direct to Phase II or Fast-Track application) around the time-sensitive environmental health science described in the topic, and you submit through ASSIST, Grants.gov Workspace, or an institutional system-to-system solution. In your application you signal fit with the topic and, where useful, name the most appropriate Institute on the assignment request form. NIH's Center for Scientific Review then assigns your application to the best-fit participating component.
If your project depends on a formal partnership with a university or other nonprofit research institution, the companion STTR announcement, PA-27-102, is the better route. Both SBIR and STTR make the award to the small business. Note also that the Highlighted Topic stays open until August 10, 2028, while PA-27-100 itself expires April 6, 2027, so applicants submitting after that date should apply through whatever reissued Parent SBIR announcement is current at that time.
What kind of research is NIH looking for?
Three parts of NIH are participating in this topic, and each brings a distinct angle. Reading their interests closely is the difference between a fundable application and a near miss.
The National Institute of Environmental Health Sciences (NIEHS) is the anchor. NIEHS wants studies that clarify the relationship between environmental exposure and health outcomes. That includes the immediate and short-term health effects that follow a disaster, methods for measuring and characterizing human exposure to environmental hazards, work that helps understand how contaminants move and predict where exposure will occur, and approaches to preventing or reducing exposure during a disaster event, including remediation technologies relevant to Superfund-type contamination. NIEHS specifically encourages exploratory and developmental work with clear time-sensitivity, and it will treat studies that use animals as stand-ins for human exposure as lower priority. Its Superfund Research Program is interested where the work applies to hazardous waste sites. Its Workers Training Program is not part of this topic. Scientific contact: Toccara Chamberlain, M.A., toccara.chamberlain@nih.gov.
The National Institute on Aging (NIA) is interested in the same time-sensitive framing but focused on older adults, whose bodies are less able to absorb the stress of a disaster and who often depend on medication, caregivers, and health services that a disaster can disrupt. NIA wants early exposure and health data captured in older populations, including people in assisted living, nursing homes, rural areas, and other at-risk settings, to understand effects on functional status, cognition, cardiometabolic health, mobility, resilience, and progression toward Alzheimer's disease and related dementias. Applications should point toward modifiable risk and protective factors that can inform prevention, preparedness, and recovery. Scientific contacts: Richard Kwok, PhD, richard.kwok@nih.gov, and Emerald Nguyen, PhD, emerald.nguyen@nih.gov.
The Office of Research on Women's Health (ORWH) focuses on how these unexpected events uniquely affect the health of women and girls. ORWH prioritizes rapid data and biospecimen collection that captures women's distinct health risks, including chronic disease management, reproductive and maternal health, and mental health, with attention to differences across life stages and to gaps in disaster preparedness for women with limited resources. One important detail: ORWH does not award grants directly, so any application it co-funds must still be relevant to the mission of at least one of the awarding Institutes or Centers in the topic. Scientific contact: Regine A. Douthard, M.D., M.P.H, orwhinfo@mail.nih.gov.
Across all three, the common thread is speed with scientific purpose. Reviewers and program staff want to see that the event was genuinely unforeseen, that the collection window is real, that the study is feasible inside it, and that the short-term data will feed longer-term understanding of exposure and health.
Who is eligible to apply?
Only a United States small business concern (SBC) can apply. To qualify, your company must be organized for profit with a place of business in the United States, and it must operate primarily in the U.S. or make a significant contribution to the U.S. economy. It must have no more than 500 employees, including affiliates. Ownership must meet one of two tests: either more than 50 percent owned and controlled by U.S. citizens or permanent residents (directly, or through other qualifying U.S.-owned businesses), or more than 50 percent owned by multiple venture capital operating companies, hedge funds, or private equity firms, with no single such firm owning more than 50 percent.
For an SBIR award, the Program Director or Principal Investigator must have their primary employment with the small business at the time of award and throughout the project. Foreign organizations and foreign components of U.S. organizations cannot apply, and NIH will not make awards under this announcement that involve foreign subawards or subcontracts. Companies also need to be aware of the foreign-risk and security screening that applies before award, including required disclosure of foreign affiliations for owners and covered individuals.
How much funding is available?
The dollar amount depends on which Institute your application is assigned to. The current SBA total-cost guidelines, which set the ceiling agencies can award without a waiver, are Phase I up to $323,090 and Phase II up to $2,153,927 as of April 2026. NIEHS, the lead Institute for this topic, uses those SBA guideline amounts for both phases, so an environmental exposure study routed to NIEHS would generally target up to about $323,090 for Phase I and up to about $2,153,927 for Phase II.
If your project skews toward aging and is assigned to NIA, the caps are higher: up to $700,000 for Phase I and up to $3,000,000 for Phase II. For applications ORWH co-funds, the Phase II reference is $2,500,000, though ORWH itself does not make the award. These are guideline amounts, and NIH may exceed them for approved waiver topics. If you plan to request more than the SBA guideline, NIH strongly encourages you to contact the relevant Institute early. No cost sharing is required, and SBIR does not take equity.
There is one work-share rule that startups sometimes overlook and that shapes the budget. In Phase I, the small business normally performs at least two-thirds (about 67 percent) of the research or analytical effort, so consultants and subcontractors together are generally capped near 33 percent. In Phase II, the small business normally performs at least half (50 percent), so outside effort is generally capped near 50 percent. Deviations are possible but must be approved in writing.
What is the timeline and what are the deadlines?
The Parent SBIR (PA-27-100) was posted May 28, 2026, opened for submission on August 5, 2026, and carries three standard due dates before it expires on April 6, 2027:
September 5, 2026, for the first cycle. Because September 5 is a Saturday and Labor Day falls on Monday, September 7, NIH's weekend and holiday policy moves the effective deadline to Tuesday, September 8, 2026. Confirm the displayed date in ASSIST or Grants.gov before you submit.
January 5, 2027, for the second cycle.
April 5, 2027, for the third cycle.
All applications are due by 5:00 PM local time of the applicant organization, and NIH does not accept late applications. After submission, an application moves through scientific merit review, then Advisory Council review, then the earliest possible start date. For the September 2026 cycle, that path runs through review in November 2026, Council in January 2027, and an earliest start around April 2027. The later cycles follow the same rhythm a few months out.
Because registration in SAM.gov, eRA Commons, Grants.gov, and the SBA Company Registry can take six weeks or longer, the practical deadline for a first-time applicant is well before the submission date. Start the registrations now if you have not.
What are the funding phases?
Phase I establishes technical merit and feasibility and normally runs up to six months. Phase II continues the research and development toward commercialization and normally runs up to two years. NIH also offers two accelerated paths that other agencies do not. Direct to Phase II lets a company that has already demonstrated feasibility, without ever holding a Phase I SBIR or STTR for that project, apply straight into Phase II. Fast-Track lets you submit and review Phase I and Phase II together to reduce the funding gap between them. After Phase II, NIH expects the company to commercialize using non-SBIR funds, whether private capital, sales, licensing, or other federal sources.
Is this a good fit for my company?
This topic is a strong fit if your company works on environmental exposure measurement, sensing, remediation, biomonitoring, rapid data or biospecimen collection, or health surveillance tied to disasters and emerging environmental threats, and if you can credibly move fast enough to capture data inside the event window. It fits especially well for teams building tools or study capabilities relevant to older adults or to the distinct health needs of women and girls, given NIA's and ORWH's participation. It is a weaker fit if your work has no time-sensitive collection element, relies mainly on animal surrogates for human exposure, or cannot meet the small business and PI employment rules. If you are unsure which Institute fits or whether SBIR or STTR is the right route, that is exactly the kind of question worth resolving before you write a single specific aim.
Frequently Asked Questions
Can I apply directly to the environmental health Highlighted Topic?
No. It is not a funding opportunity and has no application package. You apply through the NIH Parent SBIR announcement, PA-27-100, and align your research aims with the topic so it routes to NIEHS, NIA, or ORWH.
What is the next deadline?
The next Parent SBIR standard due date is September 5, 2026. That date is a Saturday just before Labor Day, so under NIH policy the effective deadline moves to Tuesday, September 8, 2026. The following cycles are January 5, 2027, and April 5, 2027.
How much money can a startup receive?
Under current SBA guidelines, Phase I runs up to about $323,090 and Phase II up to about $2,153,927. NIEHS uses those guideline amounts. NIA offers higher caps of up to $700,000 for Phase I and up to $3,000,000 for Phase II. The exact ceiling depends on the Institute your application is assigned to.
Who is eligible?
A U.S. small business concern with no more than 500 employees, organized for profit, and meeting NIH's ownership tests. For SBIR, the Principal Investigator's primary employment must be with the small business.
Do I need a university partner?
Not for SBIR. If your project depends on a formal collaboration with a university or nonprofit research institution, use the companion STTR announcement, PA-27-102, instead. In both programs the award goes to the small business.
What kind of research does NIH want here?
Time-sensitive studies that capture exposure and health data during the short window after a natural or human-made disaster or an emerging environmental threat in the United States, including short-term health effects, exposure measurement, contaminant movement, remediation, effects on older adults, and effects on women and girls.
Is the SBIR program still funded?
Yes. The SBIR and STTR programs were reauthorized in April 2026 and are currently authorized through September 30, 2031.
How long does it take to get funded?
Plan on several months from submission to award. For the September 2026 cycle, scientific review is expected in November 2026, Council review in January 2027, and the earliest start date around April 2027.
What if I miss the September deadline?
The Parent SBIR has additional standard due dates on January 5, 2027, and April 5, 2027. The Highlighted Topic itself stays active through August 10, 2028, so the priority persists across cycles, though the specific Parent SBIR announcement is reissued periodically.
