摘要：

We report on the design and construction of a laser scanning photothermal microscope and present images of gold nanoparticles of size as small as 5nm. Laser scanning method allows fast image acquisition at 80s pixel dwell time so that a 500x500 pixel image is acquired in 20s. Photothermal imaging at fast time scales can have potential applications in variety of fields including tracking of biomolecular transport processes.
