  • Publication number: 20230272271
    Abstract: Protected quantum dots are protected from degradation, particularly in aqueous environments, The system comprises quantum dots, hydrophobic core, and hydrophilic shell. The quantum dots are entrapped in and protected by the hydrophobic core. The core polymer is covalently bonded to a hydrophilic shell polymer or protein. Quantum yield is better maintained than for non-encapsulated quantum dots in an aqueous environment. Optionally, ligands are attached to the hydrophilic shell to target delivery of the protected quantum dots, In an alternative embodiment, quantum dots are entrapped in the hydrophilic shell, or in both the shell and the core.

  • Publication number: 20210235690
    Abstract: Described herein are blood storage containers that can contain a CeONP composition and/or coating on an object surface. In some aspects, the blood storage container can include an insert. In some aspects the inserts can contain a CeONP compositions and/or coating on an object surface. In aspects, the CeONP composition and/or coating on an object surface can be effective to increase the useful storage lifespan of blood, blood product, and/or component thereof stored in the blood storage container. Also described herein are methods of making and using the CeONP compositions, coatings, and devices containing the CeONP compositions and/or coatings described herein.
