Bubble-pen lithography (BPL) is a novel optically controlled nanofabrication technique that can be widely applied to pattern colloidal and biological particles on substrates in order to build functional optic, electronic, and magnetic devices. In BPL, an optically controlled microbubble is generated to capture and immobilize colloidal particles on the plasmonic substrates. With this new lithographic technique, the researchers can generate bubbles down to 1 micron in diameter. The smaller bubbles provide an enhanced patterning resolution.
