Fabrication of protein-conjugated silver sulfide nanorods in the bovine serum albumin solution.
Highly ordered silver sulfide nanorods conjugated with the Bovine Serum Albumin (BSA) protein have been successfully achieved at ambient temperature. Such a process is very simple and controllable, directly using silver nitrate and thioacetamide (TAA) as the reactants in the aqueous solution of BSA. The products have been characterized by XRD, HRTEM-SAED, SEM-EDS, TG-DTA, FT-IR, and CD spectroscopy. The results of the research show that the as-prepared Ag2S nanorods are monodispersed with sizes about 40 nm in diameter and 220 nm in length, and exhibit a high degree of crystallinity and good photoluminescence. Furthermore, an interesting mechanism is discussed for the formation of the Ag2S nanorods.
