Reflection mode polarimetry guides laser mass spectrometry to diagnostically important regions of human breast cancer tissue

Scientific Reports
To enhance the clinical utility of mass spectrometry (MS), lengthy dwell times on less informative regions of patient specimens (e.g., adipose tissue in breast) must be minimized. Additionally, a promising variant of MS known as picosecond infrared laser
