A surface modification method has been developed to fabricate surface plasmon resonance (SPR) chip for small molecule determination. A novel denaturalised bovine serum albumin (dBSA)-SPR-chip was fabricated by a self-assembling method, while a dextran-SPR-chip was prepared by using a traditional method. The surface morphologies of the two chips were investigated by atomic force microscopy technology...
This research introduces a homemade high throughput surface plasmon resonance imaging electrochemical system which can detect more than 50 spots simultaneously. The SPRI system was constructed in the Kretschmann configuration and the SPR sensor chip served as the working electrode in the EC module. K3Fe(CN)6 solution were tested by the cyclic voltammetry (CV) method and the SPRI method recording more...
In this paper, we propose a non-invasive detection method of lung cancer combined with a sort of virtual SAW gas sensors array and imaging recognition method. A patient's breath goes through an electronic nose with solid phase micro extraction (SPME) and capillary column for pre-concentration and separation of volatile organic compounds (VOCs) respectively, a pair of SAW sensors one coated with a...
