Dual drug release from electrospun poly(lactic-co-glycolic acid)/mesoporous silica nanoparticles composite mats with distinct release profiles.
The aim of this study was to fabricate dual drug-loaded poly(lactic-co-glycolic acid) (PLGA)/mesoporous silica nanoparticles (MSNs) electrospun composite mat, with the two model drugs (fluorescein (FLU) and rhodamine B (RHB)) releasing in separate and distinct release kinetics. The PLGA-based electrospun mat loading with the same amount of FLU (5%, with respect to the weight of PLGA) and different amounts of RHB-loaded MSNs (5, 15 and 25%, with respect to the weight of PLGA) were prepared and studied for their releasing properties. The morphology of the composite mats was characterized by scanning electron microscopy and transmission electron microscopy. Finally, the release profiles of the dual drug-loaded electrospun mats were measured, and the results indicated that the FLU and RHB released from the PLGA/FLU/RHB-loaded MSNs electrospun mats showed separate and distinct profiles. Most of the FLU was released rapidly during the 324 h of the trial; however, RHB showed a sustained release behavior, and the release rate could be controlled by the content of the RHB-loaded MSNs in the electrospun mat.
