Optical and Photoacoustic Imaging : Opportunities and Challenges.

Optical and photoacoustic imaging plays an important role in biomedical applications owing to its noninvasiveness and high resolution. Fluorescence imaging and photoacoustic imaging emerge as powerful tools to deconstruct molecular information and investigate biological processes . Despite great progress has been achieved in chemical probe synthesis, how to design probes with optimal fluorescence or photoacoustic imaging performance to dynamically visualize the biological process still faces challenges. From this perspective, we will focus on the advanced development of fluorescence and photoacoustic imaging . Furthermore, concerns and prospects for future imaging will be demonstrated.
