The use of particles in biological assays and other applications dated back many decades. Assays and detection systems made by coupling affinity ligands to particles of nanometer or macrometer diameter have been used in diagnostic tests and numerous other research procedures. Latex microspheres and gold nanoparticles parhaps were the earliest example of solid phase spheres used for purposes. With recent explosion in nanotechnology, the relevant particle size has shrunk by 2-3 orders of magnitude adn the applications for particles have dramatically expanded. Nanoparticles and macroparticles are used in agglutination tests and assays, particle capture ELISA methods, lateral flow tests, solid phase assays, polymerase chain reaction (PCR) tests, Luminex bead-based assay, superparamagnetic-based assay and magnetic seperation system , biosensors, fluorescent labels or stains for detecting biological molecules.
