The National Science Foundation (NSF) Directorate for Technology, Innovation and Partnerships (TIP) announces its intent to solicit Written Proposals for NSF X-Labs teams in the technical domain of bioengineering. This NSF X-Labs announcement is issued under the Other Transactions Agreement Solutions Offering (OTASO), NSF-OTASO-FY26-XLabsInitiative.
An NSF X-Labs Mission in this Topic must be transformative, accelerating breakthroughs in our understanding of the relationship between sequence and function, and catalyzing capabilities to engineer proteins or entire genomes with exceptional new capabilities. Successful teams will develop platform technologies, demonstrate measurable impact on the U.S. biotechnology landscape, and position their technologies for widespread use by overcoming technical barriers that limit implementation and investment. Although NSF X-Labs in this space will have widespread applicability, each team should identify 2-3 high-utility domains and should eventually establish projects in them. Teams proposing to this topic should identify how their approach to biosafety and biosecurity is tailored to their Mission and its pilot application domains including an assessment of dangerous gain-of-function and an accompanying plan to mitigate unintended consequences.
Limited submission criteria: An eligible organization can submit a maximum of two Written Proposals per Topic Announcement for Phase 0 as a lead organization. Senior/Key Personnel may be listed on a maximum of one Written Proposal per Topic Announcement.
Join the NSF TIP team for a webinar, including a brief presentation on key materials in the OTASO and Topic Announcement. A Q&A will follow the presentation. Respondents are recommended to review NSF-OTASO-FY26-XLabsInitiative and this Topic Announcement before the webinar to maximize the effectiveness of the Q&A session. Q&A Webinar for NSF X-Labs – From Sequence to Function November 18, 2026 at 2-3 p.m. Eastern Register here: https://nsf.zoomgov.com/webinar/register/WN_a-Ik_TCBSMDM7dFPYUEcA#/registration
