Photothermal control and in situ monitoring of a reversible biomolecular reaction on nanoparticle surfaces is demonstrated. DNA‐linked gold nanoparticle networks are disassembled through laser irradiation. The laser‐induced temperature increase is quantified using interferometry and network melting analyses.
