摘要

Authentication of commercial products has been advanced with the application of fluorescent nanomaterials. To develop a mechanically reliable material with security encoding characteristics, it has been critical to enhance the engineering process of hosting components and optical agents. Using the technology of electrospinning, novel fluorescent nanofibrous membranes were prepared. These nanofibers are environmentally friendly, mechanically reliable, and fluorescent. Perylene-labelled nanosilica particles (PNSi; fluorescence agent) are encapsulated in polylactic acid (PLA) nanofibers (hosting agent). Different pigments were used to create two distinct types of fluorescent nanofibers, including the salts of perylene monoimide potassium (PMIP) and monoimide sodium (PMIS). An effective dispersion of fluorescent perylene-labelled nanosilica particles in a polylactic acid solution without the formation of aggregates is essential for the formation of a colorless nanofibrous membrane. Fluorescent nanosilica particles (NSi) with diameters of 6–28 nm were synthesized. The prepared electrospun nanofibers combined with PMIP or PMIS showed a fiber diameter of 50–150 nm. Electrospun nanofibers showed an emission band at 568 nm and an absorbance peak at 426 nm. The produced nanofibrous membranes exhibited reversible emission without fatigue when exposed to ultraviolet light multiple times. The potential cytotoxic effects of PNSi@PLA nanofibers were investigated.
