nanoparticles, A first compound comprising a probe and bound to the surface of the nanoparticles, a second compound comprising a DNA sequence encoding the probe and bound to the surface of the nanoparticles, and optionally bound to the surface of the nanoparticles As a nanostructure comprising a substituted or unsubstituted polyalkylene glycol, when the nanostructure does not include a substituted or unsubstituted polyalkylene glycol bonded to the surface of the nanoparticle, The ratio ((n 1 +n 2 )/w) of the sum of the number of moles of the first compound (n 1 ) and the number of moles of the second compound (n 2 ) to the weight (w) of the nanostructure is 1.2 nmol/ Provided are a nanostructure of g to 85 μmol/g, a biosensor including the nanostructure, and a method for screening a biological material using the nanostructure or the biosensor. |
