Abstract

<p>An ultrahighly sensitive sensor for low-weight chemical substances, such as explosives, named electronic dog nose, was developed using a surface plasmon resonance (SPR) method with antigen-antibody interaction. The sensor surface was fabricated from a self-assembled monolayer made of poly(ethylene glycol), the end of which is composed of an antigen analogue or OH group, to be able to use it repeatedly over 100 times. A demonstration experiment conducted to detect a typical explosive, 2,4,6-trinitrotoluene (TNT), using a constructed portable SPR sensor was successful.</p>
