Abstract

Gold nanoparticles absorb light efficiently at their resonant frequency and convert it to heat within several picoseconds. Strong laser irradiation onto those gold nanoparticles enables us to heat the surrounding materials locally and rapidly, which has been reported to be useful for cancer therapy, ultrasonic generation, microfluidic control, and so on. Because the gold nanoparticles can also act as sensing platforms for such as Raman spectroscopy under laser irradiation, development of the microfluidic control method with laser heating of gold nanoparticles is desirable to meet the requirements in lab-on-a-chip devices. Here, we present microfluidic manipulation techniques based on Marangoni effect controlled by laser heating of gold nanoisland films and our most recent outcomes.
