Notice of Intent to Sole Source Nanoparticles

The CDC/NIOSH intends to award a sole‑source contract to Lab 261 (Cina Consulting, LLC) for the production of custom micro‑ and nanoplastic particles (PVC and PET) in two precise size ranges (10 nm and 1 µm) that are fluorescently labeled green. These particles are required for an in‑vitro toxicology study investigating the health effects of inhaled micro‑ and nanoplastics. Because the exact combination of polymer type, particle size, and stable fluorescence is not available from any other vendor, the agency is bypassing competitive procurement and will accept capability statements only via email by the specified deadline. • Required items: PVC and PET particles, 10 nm and 1 µm, green fluorescent labeling. • Intended use: In‑vitro toxicology assays to assess particle deposition, cellular translocation, and toxicity. • Vendor: Lab 261 (Cina Consulting, LLC) – sole source with proven capability and prior supply to the study. • Submission: Capability/qualification statement via email to Michael Davis ([email protected]) with “PR 98999” in the subject line by 7:30 PM EST, Sept 4 2026. • Procurement value: Estimated under $250,000 (exact amount redacted). • Contract type: Sole‑source acquisition under FAR 12.201‑1 and FAR 13.106‑1(b).
