A simple and versatile miniaturized surface plasmon resonance (SPR) immunosensor enabling parallel analysis of multiple analytes or multiple samples of an analyte has been investigated for detection of a low-molecular-weight (lmw) toxin, 2,4-dichlorophenoxyacetic acid (2,4-D). A specially designed multi-microchannel SPR sensor module, integrating an(More)
Detection of TNT is an important environmental and security concern all over the world. We herein report the performance and comparison of four immunoassays for rapid and label-free detection of 2,4,6-trinitrotoluene (TNT) based on surface plasmon resonance (SPR). The immunosensor surface was constructed by immobilization of a home-made(More)
In modern biomedical technology, development of high performance sensing methods for dopamine (DA) is a critical issue because of its vital role in human metabolism. We report here, a new kind of bioaffinity sensor for DA based on surface plasmon resonance (SPR) using a D(3) dopamine receptor (DA-RC) as a recognition element. A conjugate of DA was(More)
We have developed a new immunosensor based on self-assembly chemistry for highly sensitive and label-free detection of 2,4,6-trinitrotoluene (TNT) using surface plasmon resonance (SPR). A monolayer of amine terminated poly(ethylene glycol) hydrazinehydrochloride (PEG-NH(2)) thiolate was constructed on an activated gold surface and immobilized with(More)
