    FIGURE 1. Schematic principle of waveguide-enhanced Raman spectroscopy (WERS). The excitation laser propagates in a waveguide; the evanescent field of the waveguide mode excites the analyte present at the surface of the chip. Some of the generated Raman signal is collected by the waveguide and guided to the spectrometer for detection.

    FIGURE 1. Cells can be characterized by several attributes, including size, nucleus shape, and presence and abundance of several hundred surface antigens identified so far. A solution of fluorophore-coupled antibodies matching a target antigen is mixed with the cell sample; the label-carrying antibodies only sticks to those cells presenting the antigens of interest. As those cells get exposed to a laser beam, the attached fluorophores emit fluorescence that identifies the cell in question.
