제목 Surface modification of ZAIS [(ZnxAgyInz)S2] Fluorescence Nanoparticles using biopolymers (BSA) for stability in physiological aqueous solution
초록 Quantum dots (QDs), a semiconductor nanocrystal, exhibit intriguing electronic transitions that resemble single atom behavior. Due to their unique, compositional optical and electronic properties, QDs have been applied in biological applications. Herein, cadmium-free ZAIS nanoparticle was synthesized via the sonochemical approach and utilized as a new biological probe. We introduce a simple and easy method for the surface modification of ZAIS NPs with a stable and inert biopolymers. We used BSA (Bovine Serum Albumin) as a coating biomaterial for ZAIS-MPA. ZAIS-MPA was simply passivated with BSA, which tested for its stability. As a result, it was confirmed that BSA biopolymers coat and protect ZAIS NPs for a long period of time in a physiological aqueous solution.
