Monosaccharides Sensing Characteristics of Phenylboronic Acid Monolayers

To detect low concentrations of sugars, phenylboronic acid derivatives were synthesized and their self-assembled monolayers (SAM) were formed on a gold surface. Monosaccharides sensing with the constructed phenylboronic acid monolayers were evaluated through the surface plasmon resonance (SPR) technique. These phenylboronic acid monolayers showed good sensitivity and selectivity to detect fructose at low concentrations.
