Abstract:
1. An aliphatic biodegradable photoluminescent polymer (BPLP) composition comprising: a degradable oligomer, wherein the oligomer is synthesized from a biocompatible multifunctional carboxylic acid comprising a hydroxyl group, a diol, and an amino acid; wherein the amino acid is linked as a side group to the degradable oligomer backbone; wherein fluorescence emanates from a 6-membered ring formed by a carboxylic acid group of the amino acid, an alpha carbon of the amino acid, an amide linkage formed by an amino group of the amino acid, and a central carbon of the multifunctional carboxylic acid via an esterification reaction of the carboxylic acid group of the amino acid and the hydroxyl group of the multifunctional carboxylic acid.
