Fluorescent Silica Nano-Particles and Magnetic Bead Based Immunoassay: an Optical Tool for Detection of Staphylococcal enterotoxin B in Milk for High-Throughput Screening

, , , , ,
This paper describes the use of fluorescent silica nanoparticles (FSNPs) as luminescent signal amplifiers in biological system based on digital counting of individual particles and measuring of average fluorescence intensity, because FSNPs emit intense yellow-green [...]
