Arginine plays an important role in cell division and the functioning of the immune system. We describe a novel method by which arginine can be identified using an artificial monolayer based on surface plasmon resonance (SPR). The affinity of arginine binding its recognition molecular was compared to that of lysine. In fabrication of an arginine sensing interface, a calixcrown ether monolayer was anchored onto a gold surface and then characterized by Fourier Transform infrared reflection absorption spectroscopy, atomic force microscopy, and cyclic voltammetry. The interaction between arginine and its host compound was investigated by SPR. The calixcrown ether was found to assemble as a monolayer on the gold surface. Recognition of calixcrown monolayer was assessed by the selective binding of arginine. Modification of the SPR chip with the calixcrown monolayer provides a reliable and simple experimental platform for investigation of arginine under aqueous conditions. © 2011 by the authors; licensee MDPI, Basel, Switzerland.
