Synthesis of
p
-nitrophenyl N-acetyllactosaminide with β-D-galactosidase, chemical reduction of the p-nitrophenyl group, and sialylation with sialyltransferase. The
p
-aminophenyl glycosides are then successfully biotin-labeled through the coupling with N-(+)-biotinyl-6- aminohexanoic acid to afford biotinylated oligosaccharides with an aminohexanosyl group and phenyl group as the spacers between the biotin and glycan.
The SERS (surface-enhanced Raman scattering) of cyclohexyl isocyanide that silver nanoparticles modified with N-(+)-biotinyl-6-aminocaproic acid and cyclohexyl isocyanide can be anchored on a separate biotinylated substrate via the avidin-biotin interaction.
