Join us for the QCB Seminar featuring Wei Min, Columbia.
Lighting up chemical bonds for biomedicine
Abstract: Innovations in imaging have revolutionized life science and medicine. Among various imaging modalities, vibrational imaging has emerged as a major technology, by visualizing the fundamental chemical bonds inside living cells and tissues with high sensitivity, speed, specificity and resolution. In this talk I will first introduce recent advances in theoretical understanding and technical innovations of vibrational imaging. In particular, I will discuss stimulated Raman scattering (SRS) microscopy, which can amplify the otherwise feeble Raman scattering signal by up to 100 million times. Then I will highlight new research areas and applications in biomedicine and environmental science, including (1) single-molecule chemical spectroscopy, (2) single-particle nanomedicine and nanoplastics, (3) super-resolution chemical nanoscopy, (4) super-multiplexed imaging for brain mapping, and (5) vibrational spatial omics.
