Development surface plasmon sensor with multi channel and measurement of residual antibiotics

An analytical method using surface plasmon resonance (SPR) is one of the most powerful methods for evaluating biomolecule interaction. Conventional SPR sensor, however, were not suitable for on-site analysis because of the size, weight and cost of the instruments. In this study, we attempted to develop a new portable-type SPR sensor with multi detection points for on-site analysis. The SPR sensor had the new optical system which consisted of a LD light, a multi-beam splitter, a sensor prism and a PD array. The sensor was able to detect residual antibiotics in milk.
