Nano Discovery LLC is a bioassay company dedicated to the development of bioassays using nanotechnology tools. They develop and conduct immunoassays on a wide range of biomolecular targets for research and development needs. The core technology is a one-step homogeneous immunoassay method, nanoDLSAY that combines the use of gold nanoparticle optical probes with dynamic light scattering detection. This immunoassay is extremely easy to conduct, offers high sensitivity and requires small volumes of sample solutions for analysis.
