Abstract: Surface enhanced Raman spectroscopy is employed to obtain chemical data with respect to cells while electrophysiological data relating to cell membranes is obtained using the patch clamp technique. A SERS-facilitating assembly is coupled to a micropipette and is used in conjunction with a monochromatic light source for generating scattered light. Surface enhanced Raman spectroscopy is employed to obtain the chemical data. Electrophysiological data is obtained using the same micropipette to perform the patch clamp technique.

Abstract: Systems and methods for hyperspectral imaging are described. In one implementation, a hyperspectral imaging system includes a sample holder configured to hold a sample, an illumination system, and a detection system. The illumination system includes a light source configured to emit excitation light having one or more wavelengths, and a first set of optical elements that include a first spatial light modulator (SLM), at least one lens, and at least one dispersive element. The illumination system is configured to structure the excitation light into a predetermined two-dimensional pattern at a conjugate plane of a focal plane in the sample, spectrally disperse the structured excitation light in a first lateral direction, and illuminate the sample in an excitation pattern with the one or more wavelengths dispersed in the first lateral direction.
