Ultra-Sensitive Photoacoustic Microscopy Enables New Biomedical Applications

Optical-resolution photoacoustic microscopy is an up-and-coming biomedical imaging technique for studying a broad range of diseases, such as cancer, diabetes, and stroke. But its insufficient sensitivity has been a longstanding obstacle for its wider application. Recently, a research team from City University of Hong Kong (CityU) developed a multi-spectral, super-low-dose photoacoustic microscopy system with a significant improvement in the system sensitivity limit, enabling new biomedical applications and clinical translation in the future.
