Figure Lengend Snippet: UV–Vis spectroscopy and color change observation during the extracellular biosynthesis of SeNPs using L. fermentum . The color changed from pale yellow ( A) to red color ( B) after the incubation time indicating the successful formation of SeNPs
Article Snippet: Optimized SeNPs and Se/CS NC were characterized spectrophotometrically using a double beam spectrum UV–Vis spectrophotometer (V-760, JASCO, UK), Fourier transform infrared spectroscopy (FT-IR, JASCO, UK), and X-ray diffraction (XRD) analysis which was performed using an X-ray diffractometer (LabX XRD-6000, Shimadzu, Japan).
Techniques: UV-Vis Spectroscopy, Incubation
