## Abstract of Patents and Patent Application(s)

I. Oxygen-sensing materials and methods are disclosed. The materials include oxygen-sensing chromophores embedded in a solid matrix including silk fibroin in an amount by weight of at least 50% of the total weight of the solid matrix. The solid matrix possesses at least partial transparency at relevant wavelengths. The solid matrix is biocompatible and biodegradable. The solid matrix is not a hydrogel. The chromophores are distributed throughout the solid matrix. Tissue oxygenation can be estimated from phosphorescence measurements made from oxygen-sensing materials implanted in subject.

## Intellectual Property

*Silk-chromophore Composite Materials for in situ Oxygen Sensing.*                     The invention is protected under U.S. Provisional Patent Application Serial No.63/317,929, filed on March 8, 2022, PCT Patent Application Serial No. PCT/US2023/014796, filed on March 8, 2023, U.S. Patent Application Serial No. 18/823,853, filed on September 4, 2024.                

The Department of the Air Force may grant the prospective license unless a timely objection is received that sufficiently shows the grant of the license would be inconsistent with the Bayh-Dole Act or implementing regulations. A competing application for a patent license agreement, completed in compliance with 37 CFR 404.8 and received by the Air Force within the period for timely objections, will be treated as an objection and may be considered as an alternative to the proposed license.

*Authority:*35 U.S.C. 209; 37 CFR 404.                

Tommy W. Lee,

Acting Air Force Federal Register Liaison Officer.
