Quercetin-gold nanorods incorporated into nanofibers: development, optimization and cytotoxicity.

Herein, a polymeric nanofiber scaffold loaded with Quercetin (Quer)-gold nanorods (GNR) was developed and characterized. Several parameters related to loading Quer into GNR, incorporating the GNR-Quer into polymeric solutions, and fabricating the nanofibers by electrospinning were optimized. GNR-Quer loaded into a polymeric mixture of poly(lactic--glycolic acid) (PLGA) (21%) and poloxamer 407 (23%) has produced intact GNR-Quer-nanofibers with enhanced physical and mechanical properties.
