Frequently Asked Questions (FAQs): NSF Biophotonics (PD 13-7236)

What is the NSF Biophotonics funding opportunity (PD 13-7236) about?

This NSF opportunity supports fundamental research in photonics that can unlock new capabilities in medicine, biology, and biotechnology. The focus is on early-stage, science-and-engineering-driven innovation, especially breakthroughs in how light is generated, controlled, delivered, and measured in biological settings.

What kind of work is this program trying to fund?

The program is geared toward potentially transformative research rather than incremental improvements to technologies that are already mature or close to routine clinical use. Proposed work should make a clear engineering science contribution and explain why the approach is novel compared to prior work in the field.

What outcomes or impacts is NSF looking for?

NSF is interested in advances that could enable the next wave of medical diagnostics and therapies, particularly approaches that may be low cost and minimally invasive. Proposals are expected to project potential societal and/or industry impacts if the research succeeds.

What are the main technical focus areas highlighted by the solicitation?

The solicitation highlights several themes where advances are considered especially valuable, including:

• Nanophotonics and micro- or nano-photonic platforms for biomedicine
• Improved contrast and targeting agents
• Ultra-thin probes and wide-field imaging methods designed for real-world biological or clinical constraints
• Rapid biomarker screening using optical approaches
• Neurophotonics and optogenetics (as priority directions)

Does my project have to fit exactly one of the listed example topics?

No. The solicitation provides concrete examples of topics that fit well, but it also leaves room for innovative proposals outside those exact categories. However, it explicitly recommends contacting the Program Director before submission to reduce the risk of an out-of-scope proposal being returned without review.

What does NSF mean by nanophotonics or nano-photonic platforms for biomedicine?

In this program context, nanophotonics and micro/nano-photonic platforms include nanoscale materials and devices intended to interrogate biological systems with improved sensitivity, resolution, or throughput compared to existing approaches.

What types of imaging or probe advances are called out?

The solicitation emphasizes improved contrast and targeting agents, ultra-thin probes, and wide-field imaging methods that can better align optical tools with practical biological and clinical constraints (for example, safe operation in tissue, compact form factors, or imaging larger areas without sacrificing speed or signal quality).

What is meant by "rapid biomarker screening" in this program?

Rapid biomarker screening refers to optical approaches that can quickly detect or quantify disease indicators, with an emphasis on methods that avoid slow, expensive, or highly invasive procedures.

What are "macromolecule markers" and why are they a fit for this solicitation?

Macromolecule markers are cited as an example topic where NSF is interested in innovative labeling strategies for macromolecules and new compositions of matter or fabrication approaches for multicolor probes. The emphasis is on methods that push optical sensing toward the limits of detection, resolution, and identification, enabling more precise marking and detection of specific pathological cells (not simply a new dye or tag).

What is "low-coherence sensing at the nanoscale" and what methods are included?

The solicitation highlights low-coherence sensing at the nanoscale as an example area, including approaches such as low coherence enhanced backscattering (LEBS), multidimensional elastic light scattering, and angle-resolved low coherence interferometry. These methods aim to extract subtle structural or compositional information from tissue by analyzing how light scatters.

Are early cancer detection applications relevant to this program?

Yes. The solicitation specifically notes applications such as early cancer detection (including dysplasia) in connection with low-coherence sensing and scattering-based approaches.

How does the program define neurophotonics priorities?

For neurophotonics, NSF highlights studies of photon activation of neurons at interfaces where nanomaterials are attached to cells, and the development of biocompatible photonic tools that can act as parallel interfaces and interconnects for communication with, and control of, neural networks.

How does the program define optogenetics priorities?

For optogenetics, the solicitation emphasizes using light-activated channels and enzymes to manipulate neural activity with fine temporal precision. This points toward enabling technologies for stimulation, control, and potentially readout in complex neural systems.

What is the typical award duration for unsolicited projects?

Unsolicited awards under this program are generally expected to run one to three years.

What are the typical funding levels for this program?

The solicitation states typical average annual award sizes of about:

• $100,000 per year for single-investigator projects
• $200,000 per year for multi-investigator projects

What happens if a proposal budget is substantially higher than the typical levels?

The program warns that proposals requesting substantially more than the typical amounts may be returned without review unless the PI consults the Program Director in advance.

Is cost sharing or matching required?

No. The posted opportunity information indicates there is no cost sharing or matching requirement.

How much total funding and how many awards are expected?

The opportunity information indicates an estimated total funding amount of $6.6 million and an expectation of roughly 26 awards.

Who is eligible to apply?

Eligibility is described as unrestricted (open to any type of entity), subject to any clarifications in the program text.

Which NSF area does this opportunity fall under?

The opportunity sits within NSF Engineering under CFDA 47.041 (Engineering Grants) and is categorized under science and technology research and development.

When can proposals be submitted?

Proposals must be submitted during the announced proposal window. The archived solicitation shows historical submission windows and closing dates, and the key rule stated is that unsolicited proposals received outside those window dates are returned without review.

What should applicants emphasize in the proposal narrative?

Proposals should clearly explain what is novel and potentially transformative compared to prior efforts, and make a strong case for why the research matters from an engineering science standpoint. Applicants are also expected to describe potential societal and/or industry impacts if the research succeeds.

Where should the novelty or transformative claim appear?

The solicitation notes that the novelty or transformative nature of the work should appear at minimum in the Project Summary, not buried later in the narrative.

Are reviewer scores the only factor in funding decisions?

No. NSF notes that final funding decisions can consider more than reviewer scores alone, including balancing subfields, overall program funds, overlap with other funding sources, and broader NSF policies and priorities.

Does this program encourage CAREER proposals?

Yes. The announcement encourages submission of Faculty Early Career Development (CAREER) proposals, which are five-year awards with an Engineering CAREER deadline typically in July each year.

Can I submit proposals for conferences, workshops, or supplements under this opportunity?

The solicitation notes that conference, workshop, and supplement proposals should ideally be submitted during the regular annual proposal window, and investigators are encouraged to discuss such requests with the Program Director ahead of time.

Are RAPID or EAGER submissions possible?

NSF indicates it may consider RAPID and EAGER mechanisms when appropriate, but these require prior discussion with the Program Director before submission.

Is it recommended to contact the Program Director before submitting?

Yes. The solicitation explicitly recommends contacting the Program Director before submission, especially to reduce the risk of an out-of-scope proposal being returned without review and to discuss cases such as higher-than-typical budgets, conference/workshop/supplement requests, and RAPID/EAGER mechanisms.
