Nanomaterials with component particle sizes in the rangeof a few to hundreds of nanometers can exhibit intriguing and extraordinaryproperties compared to their bulk counterparts. In addition to the well-knownexample of nano-gold appearing ruby red instead of the familiar yellow of bulkgold, the striking properties of nanomaterials provide tremendous opportunitiesfor many new applications. The precise control and manipulation ofnanomaterials at the single-particle level are an area of active interest. Twomethods can be used for this purpose:

A “laser-induced nano-bullet” for additivenanofabrication: This method enables selective release of a single nanoparticlein the air and additive transfer of it from one substrate to another substrate.In-plane and out-of-plane nano-dimers with sub-5nm gaps have been fabricatedwith this method.

A “laser-induced surface bubble” for particlemanipulation and sensing: A laser-induced surface bubble is used to rapidfabricate SERS substrate for ultrasensitive sensing.
