One-step synthesized silver micro-dendrites used as novel separation mediums and their applications in multi-DNA analysis.

A new kind of silver micro-dendrites have been synthesized for the separation and multiplex detection of DNA merely by earth gravity. Through this approach, the DNA strands of the sickle cell disease, human T-lymphotropic virus type I, the anthrax lethal factor can be detected down to 100 pM with the detection range from 100 pM to 100 nM at the same time.
