Various nanoparticles have been prepared,characterized and used as labels for highly sensitive bioassay of DNA and protein biomarkers.The use of functional quantum dots,carbon nanotubes,silica nanoparticles,and protein-case as labels for signal amplification will be discussed.This method is simple,selective,and reproducible for biomarker detection.The new nanomaterials-based labels have been used for highly sensitive electrochemical detection of DNA and protein biomarkers.The high sensitivity and selectivity make these labels a useful addition to the armory of nanoparticle-based bioassays.The new nanoparticles based labels hold great promise for multiplex protein and DNA detection and for enhancing the sensitivity of other bioassays.
