Abstract: We designed and synthesized phenylboronic acid as a molecular recognitionmodel system for saccharide detection. The phenylboronic acid derivatives that haveboronic acid moiety are well known to interact with saccharides in aqueous solution; thus,they can be applied to a functional interface of saccharide sensing through the formation ofself-assembled monolayer (SAM). In this study, self-assembled phenylboronic acidderivative monolayers were formed on Au surface and carefully characterized by atomicforce microscopy (AFM), Fourier transform infrared reflection absorption spectroscopy(FTIR-RAS), surface enhanced Raman spectroscopy (SERS), and surface electrochemicalmeasurements. The saccharide sensing application was investigated using surface plasmonresonance (SPR) spectroscopy. The phenylboronic acid monolayers showed goodsensitivity of monosaccharide sensing even at the low concentration range (1.0 × 10-12 M).The SPR angle shift derived from interaction between phenylboronic acid andmonosaccharide was increased with increasing the alkyl spacer length of synthesizedphenylboronic acid derivatives.
Keywords: phenylboronic acid; self-assembled monolayer; saccharide detection; surface plasmon resonance.
