Researchers can now build an inexpensive and flexible micro-Raman system

Raman spectroscopy provides detailed chemical information, and when combined with a microscope, it can non-destructively analyze biological samples. While commercial research-grade Raman microscopes have been available for some time, they have tended to be both inflexible and very expensive. In a paper in the current issue of Biomedical Spectroscopy and Imaging, researchers from Germany and Serbia describe an inexpensive, versatile micro-Raman system that can be assembled from readily available
