Abstract
Using a water-immersion optical objective in conjunction with a miniature 40-MHz ultrasonic transducer, we developed reflection-mode photoacoustic microscopy with a transverse resolution as high as 320 nm. Here, we further integrated two-photon microscopy capability into the system to enable multimodality in vivo biomedical imaging at submicron resolution. As a result, the system is capable of tri-modality label-free imaging of microvasculature, collagen, and cell morphology, based on the contrast of optical absorption, second-harmonic generation, and autofluorescence, respectively. In addition, we demonstrated simultaneous microscopic imaging of neuron and microvasculature in the brain cortex of a living mouse, which may offer new opportunities for studying the mechanisms of neurovascular coupling.
