Abstract: For the surface-optoelectronic study of Saxitoxin sensing, we fabricated self-assembled calixarene derivative monolayers as the recognition-functional interfaces ona gold surface. An interaction study between Saxitoxin and calixarene derivativemonolayers were performed using surface plasmon resonance (SPR) spectroscopy. Amongthree calixarene derivatives, calixarene crown ether SAM showed the highestsensitivity to Saxitoxin. The detection limit of this system is three orders of magnitudelower than that of the mouse bioassay which is the current benchmark for Saxitoxindetection.
