摘要:This invention provides gold nanoparticles for bio-molecule detection in body fluid and systems therefor. In one embodiment, this invention provides a method for synthesis of gold nanoparticles dispersed in solution. In another embodiment, this invention provides a method for detecting a substance directly from a sample of body fluid with SERS using the gold nanoparticles dispersed in solution. In a further embodiment, this invention provides a system, having the gold nanoparticles dispersed in solution, for on-site detection of a substance directly from a sample of body fluid with SERS.
