The bio-conjugation species produced through combining the gold and silver nanoparticles into the biomolecular surface, due to their size-dependence and dimension being similar to bio macromolecule, are very suitable for acting as a major cycle carrier of the magnetic resonance imaging and the drug release/transport, and a structure skeleton of the tissue culture project. They can also be used in biomolecular identify and label, DNA-sensor and biochip. From the point of biomedicine analysis and the clinical diagnosis, the present paper summarized the application and the development of gold and silver nanoparticles in DNA identify, biosensor, biochip and immunities analysis.
