Temperature-dependent drug release profiles of the different sets of dual drug-loaded nanofiber solutions when incubated in suspension at 4°C or 37°C for every 10 minutes.

Notes: The gray and white blocks represent 4°C and 37°C, respectively. Two different sets of the dual drug-loaded bicompartmental nanofibers were prepared: (A) a BSA-loaded poly(NIPAM-co-SA) compartment and a DMP-loaded PEGDMA compartment; and (B) a DMP-loaded poly(NIPAM-co-SA) compartment and a BSA-loaded PEGDMA compartment. The BSA from the BSA-loaded poly(NIPAM-co-SA) compartment was released at different rates at 4°C and 37°C due to the reversible conformational change of the poly(NIPAM-co-SA) chains as a function of temperature.

Abbreviations: poly(NIPAM-co-SA), poly(N-isopropylacrylamide-co-stearyl acrylate); DMP, dexamethasone 21-phosphate; PEGDMA, polyethylene glycol dimethacrylates; BSA, bovine serum albumin.
