Patent ID: 11827920

Abstract:
Disclosed are a nanostructure including a nanoparticle, and a first compound including a probe and bound to the surface of the nanoparticle, a second compound including a DNA sequence encoding the probe and bound to the surface of the nanoparticle, and optionally substituted or unsubstituted polyalkylene glycol bound to the surface of the nanoparticle, wherein when the nanostructure does not include substituted or unsubstituted polyalkylene glycol bound to the surface of the nanoparticle, a ratio ((n1+n2)/w) of the sum of the number of moles (n1) of the first compound and the number of moles (n2) of the second compound relative to the weight (w) of the nanostructure is about 1.2 nmol/g to about 85 μmol/g on average, a biosensor including the nanostructure, and a method of screening a biological material using the nanostructure or the biosensor.
