Bioanalysis has relied on tissue homogenization, separation, followed by various assays. These approaches tell the presence of molecules and their concentrations. Nevertheless, without spatial and temporal dynamics information, how molecules execute their functions in a living system remains unknown. Moreover, important target molecules with small quantities are often buried in the large background of dominant species in these in vitro assays. Professor Cheng and his research team have made seminar contributions in changing this conventional diagram of bioanalysis through leading the field of molecular spectroscopic imaging. (For details of this rising field, see Review Article in Science 2015, 350: 1054.) The Cheng research team has been constantly at the most forefront of the label-free spectroscopic imaging field in pushing the physical limits of label-free imaging, biological applications, and clinical translation, as summarized by the figure below.
