Abstract
Photoacoustic microscopy provides a new dimension of observation in microscopic life science. However, due to the high complexity of building a photoacoustic microscopy system, for many life science practitioners, it usually takes several years to build a stable photoacoustic microscopy system. For the above situation, in this paper, a productized strategy of photoacoustic (532 nm & 1064 nm) & ultrasonic co-scanning microscopy for in vivo imaging on small animals is presented. 532 nm laser is applied to image blood vessels and pigments in label-free manner. 1064 nm laser is applied to image pigments and some novel probes developed for NIR-II windows. Ultrasound is applied to assist photoacoustic imaging to accurately locate its imaging site in tissues. All three-dimensional results are obtained with one single scan. The strategy presented here will help life science practitioners to build a stable photoacoustic microscopy platform.
