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

利用表面等离子体共振(SPR)的分析方法是评价生物分子相互作用的最有力的方法之一。然而，由于仪器的尺寸、重量和成本，传统的SPR传感器不适合现场分析。在本研究中，我们试图开发一种新型的便携式多检测点SPR传感器，用于现场分析。SPR传感器具有由LD光源、多光束分束器、传感器棱镜和PD阵列组成的新型光学系统。该传感器能够检测到牛奶中残留的抗生素。

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.
