We report a novel technique for regiospecific hetero-assembly of DNA-modified precious metal nanoparticles (DNA-AuNPs) onto upconversion nanoparticles (UCNPs) into cross types lab-on-a-particle systems. stoichiometry and spatial company from the NPs at nanometer range represents a significant problem in this field.1 Recently, DNA has attracted great attention as an ideal programmable assembly agent for controllable self-assembly… Continue reading We report a novel technique for regiospecific hetero-assembly of DNA-modified precious
