ABSTRACT: Statement of significance
This manuscript describes a novel strategy of conferring intrinsic photoluminescence to the widely used biodegradable polymers, poly(lactide-co-glycolide) without introducing any cytotoxic quantum dots or photo-bleaching organic dyes, which may greatly expand the applications of these polymers in where fluorescent properties are highly desired. Given the already significant impact generated by the use of PLGA and alike, this work contributes to fluorescence chemistry and new functional biomaterial design and will potentially generate significant impact on many fields of applications such as tissue engineering, molecular imaging and labeling, and drug delivery.

Fluorescent biomaterials have attracted significant research efforts in the past decades. Herein, we report a new series of biodegradable, fluorescence imaging-enabled copolymers, biodegradable photoluminescent poly(lactide-co-glycolide) (BPLP-co-PLGA). Photoluminescence characterization shows that BPLP-co-PLGA solutions, films and nanoparticles all exhibit strong, tunable and stable photoluminescence. By adjusting the molar ratios of L-lactide (LA)/glycolide (GA) and (LA+GA)/BPLP, full degradat ...[more]
