Abstract

The present disclosure is directed to processes comprising irradiating an aggregate of chemically bonded or otherwise associated nanoparticles with a light source capable of providing multiphoton excitation, the light source directed at a focal point volume including the aggregate and having sufficient energy to disrupt or fuse the aggregate within the focal point volume to form nanoscale deposits of the nanoparticles.
