Photoacoustic Imaging of Metabolic Activities across Biological Length Scales.

Abstract

Imaging is ubiquitous with biomedical research and discovery. This article surveys the role of imaging in our understanding of metabolism and introduces photoacoustic imaging as a compelling candidate for providing high-resolution, label-free, and real-time insights into metabolic processes. As a rapidly evolving modality, photoacoustics holds promising preclinical and clinical potential in imaging of metabolism as well as metabolism-related changes.
