A Conceptual illustration of a large-scale rapid scanning laser-emission microscopy (LEM) for detecting pre-polyp nuclear abnormality by analyzing FFPE colonic tissues from mice with colon cancer risk. Here, a 10 µM thick FFPE tissue section is sandwiched within a high-Q Fabry-Pérot (FP) cavity. Adapted with permission from ⁷⁵, Copyright 2019 OPTICAL SOCIETY OF AMERICA. B and C Schematic illustration of the Indocyanine green (ICG) laser using a high Q-factor optofluidic ring resonator (OFRR), in human serum and whole blood. ICG lasing can only be achieved when ICG binds to serological components such as albumin and lipoprotein. Adapted with permission from ⁸⁵. Copyright 2016 OPTICAL SOCIETY OF AMERICA.
