NSF Nano Biosensing (PD 15-7909) - Frequently Asked Questions

1) What is the NSF Nano Biosensing program funding?

The NSF Nano Biosensing program (PD 15-7909) funds fundamental engineering research focused on creating new devices and methods to measure and quantify biological analytes, with a strong preference for approaches that leverage emerging nanotechnology.

2) What kind of work is considered a strong fit for this program?

Strong-fit projects push biosensing science beyond current capabilities rather than refining established sensor technologies. Competitive proposals clearly explain why the work matters from an engineering-science perspective and make a credible case for broader impacts.

3) What does NSF mean by “beyond current capabilities” in biosensing?

The program emphasizes advances that move biosensors into new performance regimes and new use settings. This includes performance that outperforms today’s measurement tools, works in complex real-world samples with minimal preparation, or achieves dramatic improvements in selectivity and reliability.

4) What are the priority technical areas called out in the announcement?

Priority areas include: (a) multi-purpose sensor platforms that outperform current state-of-the-art measurement tools; (b) novel transduction mechanisms and sensor architectures that can operate directly in real-world samples with minimal or no sample preparation (such as food matrices, water samples, or body fluids); (c) breakthroughs in biorecognition that dramatically improve selectivity, including concepts aimed at eliminating false negatives; (d) nanosensors that probe biology in more native conditions (including in situ kinetics/thermodynamics of biomolecular interactions and transport phenomena like transmembrane and intracellular transport); and (e) fundamental work on biosensor interfaces, including surface functionalization and immobilization strategies that influence orientation, activity, stability, and effectiveness of biorecognition molecules at the sensor surface.

5) Are incremental improvements to existing sensor technologies competitive?

The program discourages incremental improvements to established methods. Proposals are expected to emphasize novelty and the potential to be transformative rather than representing a minor refinement of existing sensors.

6) Does NSF expect experimental validation, or can the work be purely theoretical?

Experimental characterization of sensor responses to actual biological analytes is expected. Projects that remain purely theoretical or do not demonstrate meaningful experimental evaluation of sensing performance are less likely to be competitive.

7) What does NSF want to see in the Project Summary?

The Project Summary is expected to highlight what is novel or potentially transformative about the idea. It should also communicate why the work matters from an engineering-science perspective and address broader impacts.

8) What broader impacts are especially relevant for this program?

Examples flagged in the announcement include benefits to public health, environmental monitoring, food safety, industrial bioprocessing, and clinical diagnostics. Competitive proposals should make a credible broader-impact case aligned with the proposed research.

9) What types of sample environments or use settings are emphasized?

The program prioritizes sensors that can function in real-world samples with minimal or no sample preparation, including direct operation in environments such as food matrices, water samples, or body fluids.

10) What is meant by “novel transduction mechanisms” and “new sensor architectures” in this context?

Within the scope described, NSF is seeking sensing approaches that are not limited to well-established mechanisms or standard architectures. The emphasis is on fundamentally new ways to convert analyte recognition into a measurable signal and on architectures that enable operation in complex, realistic sample conditions.

11) What biorecognition advances is the program looking for?

The program calls out breakthroughs in biorecognition that dramatically improve selectivity and reliability, including concepts aimed at eliminating false negatives. It also emphasizes fundamental research on the biosensor interface, such as surface functionalization and immobilization strategies that control orientation, activity, and stability of recognition molecules.

12) What kinds of “native condition” biological measurements are highlighted?

The announcement emphasizes nanosensors that can probe biology in more realistic conditions, such as measuring kinetics and thermodynamics of biomolecular interactions in situ and studying transport phenomena like transmembrane and intracellular transport.

13) Are projects outside the listed priority areas allowed?

Innovative ideas outside the listed topics can still be considered. However, investigators are encouraged to contact the Program Director before submitting to reduce the risk of a proposal being returned without review due to poor program alignment.

14) When should we contact the Program Director (PD) before submitting?

Prior contact is encouraged if program fit is uncertain, if the project is outside the main topic list, if requesting a budget substantially above the typical level, or if considering mechanisms like RAPID, EAGER, conference/workshop proposals, or supplement requests (all of which the announcement says should be discussed in advance).

15) What is the typical award size and project duration for unsolicited awards?

Unsolicited awards are typically 1 to 3 years, with a common funding level around $100,000 per year.

16) What happens if our budget request is substantially above the typical level?

Requests substantially above the typical level may be returned without review unless the PI discusses the budget with the Program Director in advance.

17) How much total funding is associated with the program, and what are the historical award ranges?

The broader solicitation information lists an estimated total program funding of $7.6 million, and it posts historical award floor and ceiling figures of $300,000 to $600,000.

18) Is eligibility restricted to certain organization types or applicant categories?

Eligibility is listed as unrestricted in the information provided.

19) Is cost sharing required?

No. The program information states there is no cost-sharing requirement.

20) What compliance rules and submission requirements apply?

Standard NSF compliance rules apply. Proposals must follow the NSF Proposal and Award Policies and Procedures Guide (PAPPG) and must be submitted within the announced proposal window; otherwise, they can be returned without review.

21) What if our project is strongly tied to water quality?

The announcement notes that projects closely tied to water quality may be jointly supported with the Environmental Engineering program (CBET 1440).

22) Where should photonic nanosensors with medical applications be submitted?

The announcement directs photonic nanosensors with medical applications to the Biophotonics program (CBET 7236).

23) Are CAREER proposals encouraged for early-career faculty?

Yes. CAREER proposals from early-career faculty are strongly encouraged. The information provided notes that these are typically five-year awards, with engineering CAREER deadlines in July.

24) Can RAPID or EAGER proposals be used for Nano Biosensing topics?

NSF may consider RAPID and EAGER proposals when appropriate, but they require prior discussion with the Program Director.

25) Are conference, workshop, or supplement requests relevant to this program?

They may be relevant, but the announcement indicates conference, workshop, and supplement requests should be discussed with the Program Director ahead of submission.

26) Are GOALI proposals encouraged?

Yes, GOALI proposals are encouraged if they fit the program’s technical scope and are submitted during the appropriate unsolicited proposal window. GOALI proposals connect academic fundamental research with industry collaboration and translational outcomes.
