Biotin-D-Glucose is a versatile dye, essential in biological experiments for observing and analyzing cell structures, tracking biomolecules, assessing cell functions, distinguishing cell types, detecting biomolecules, studying tissue pathology, and monitoring microorganisms, with applications ranging from basic scientific research to clinical diagnostics. Dyes are also widely used in traditional areas such as textile dyeing and newer fields like functional textile treatment, food coloring, and dye-sensitized solar cells.
