Abstract

A new SPR sensor surface based onself-assembled-Calix [4] arene-derivative-monolayer was proposed for the detection of sodium in water. The immobisation of claixarene onto the gold surface was confirmed by impedance spectroscopy (EIS). Three alkaliions were used K+, Na+and Ca2+and the influence of pH on ions detection was studied and optimized. The Calix [4] arene-gold SPR sensor developed was characterized by low limit of detection (LOD) for about 10-10M, high sensitivity and wide linear detection range between 10-6M and 10-14M.
