Gold Nanoparticle-based Near-infrared Fluorescent Detection of Biological Thiols in Human Plasma

摘要

Spectrofluorimetry in the near-infrared (NIR) region is an area of increasing interest because NIR possesses many advantages over visible fluorescence, primarily due to photoprocesses of absorption and emission occurring above 650 nm [1, 2]. In the NIR, background interference from impurity molecules can be minimized because few molecules demonstrate intrinsic fluorescence in this region.
