UCNPS-SA

Gold nanoparticles modified by streptavidin (SA).Gold nanoparticles can be easily functionalized by antibody,oligonucleotide,biotin, protein A,lectin, enzyme and other key probe molecules by electrostatic modification or covalent coupling.This hybrid system of biomolecular nanoparticles is the basic building block of biosensor,targeted drug and gene delivery,photothermal therapy and biomaterial imaging.Streptavidin biotin system has the characteristics of high sensitivity,good specificity,high stability and wide application.
