Reversible Switching of DNA-Gold Nanoparticle Aggregation

Reversible Switching of DNA-Gold Nanoparticle Aggregation

Switchable formation of materials: DNA‐modified gold nanoparticles can aggregate reversibly by the employment of “fueling” oligomers that hybridize with the linker oligomers within the aggregated nanoparticles (see scheme). This approach paves the way to the generation of programmable functional mat...
