Chemical imaging plays an increasingly important role in studying heterogeneous biological systems. It combines molecular spectroscopy with high-resolution spatial information to create quantitative images of molecular distributions. Here I summarize recent progress in technical developments and biological applications of a specific chemical imaging technique-stimulated Raman scattering (SRS) microscopy. SRS microscopy allows for a wide range of molecules - both endogenous and exogenous - to be imaged at high spatial and temporal resolution in living cells, tissues, and organisms. I will focus on developments in SRS imaging that enable detection of non-fluorescent molecules and drive new biological applications.

UI	MeSH Term	Description	Entries
D008853	Microscopy	The use of instrumentation and techniques for visualizing material and details that cannot be seen by the unaided eye. It is usually done by enlarging images, transmitted by light or electron beams, with optical or magnetic lenses that magnify the entire image field. With scanning microscopy, images are generated by collecting output from the specimen in a point-by-point fashion, on a magnified scale, as it is scanned by a narrow beam of light or electrons, a laser, a conductive probe, or a topographical probe.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
