Raman Imaging of Biomedical Samples
, 2018 Fluorescence microscopy, a gold standard in the tissue or cell imaging, has several drawbacks, with a severe one being its disability to elucidate the chemical characteristics of the sample. Confocal Raman microscopy is a tempting label free alternative to fluorescence and a prospective future method of medical diagnostics.

Deuterium Raman imaging for lipid analysis
Current Opinion in Chemical Biology, 2022 Raman microscopy has been used to deduce information about the distributions of endogenous biomolecules without exogenous labeling. Several functional groups, such as alkynes (CC), nitriles (CN), and carbon-deuterium (C-D) bonds, have been employed in recent years as Raman tags to detect target molecules in cells. In this article, we review some recent

Highly Stable, Graphene-Wrapped, Petal-like, Gap-Enhanced Raman Tags
Nanomaterials, 2022 Gap-enhanced Raman tags (GERTs) were widely used in cell or biological tissue imaging due to their narrow spectral linewidth, weak photobleaching effect, and low biological matrix interference. Here, we reported a new kind of graphene-wrapped, petal-like,
