Dynamic Light Scattering System (Microplastics and Nanoparticles)

The U.S. Food and Drug Administration is seeking information from potential suppliers for a Dynamic Light Scattering system to support the analysis of nano-sized particles in food and color additives, with a focus on detecting and characterizing microplastics and nanoplastics. The instrument must accurately measure particle size, size distribution, zeta potential, electrophoretic mobility, concentration, refractive index, sedimentation, transmittance, molecular weight, and microrheology across the 1–1000 nm range to enable comprehensive characterization of dispersed materials in complex food matrices. This capability is critical to advancing the agency’s mission in evaluating the safety of engineered or incidental nanomaterials present in the food supply. The solicitation, identified as HPF-2026-134655, is posted under NAICS code 334516 and is issued by the FDA Office of Acquisition and Grant Services within the Department of Health and Human Services. Responses are due by July 31, 2026, at 4:00 p.m. Eastern Time, and the contracting office is located in Rockville, Maryland, with performance expected in College Park, Maryland. David Seid serves as the primary point of contact for inquiries, reachable via email or phone, and all submissions must align with the technical requirements outlined to ensure compatibility with the FDA’s analytical needs for food safety research and regulatory oversight.
