The unique design of the imaging head of the microscope makes it highly convenient for scalable high-resolution imaging by simply switching the optical objectives. The submicron resolution performance of the system is demonstrated via in vivo imaging of zebrafish, normal mouse ear, and a xenograft tumor model inoculated in the mouse ear. The imaging results confirm that the presented dual-modality microscopy imaging system could play a vital role in observing model organism, studying tumor angiogenesis and assessment of antineoplastic drugs %K 00-01 %K 99-00 Photoacoustic microscopy %K Confocal microscopy %K Multimodal imaging %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6423349/
