    Abstract:
    We describe the development of an acousto-optic tunable filter (AOTF) -based hyperspectral surface-enhanced Raman imaging (HSERI) system equipped with an intensified charged coupled device and an avalanche photodiode. The AOTF device is a miniature rapid-scanning solid-state device that has no moving parts and can be rapidly tuned (microseconds) either sequentially or randomly, over a wide spectral range between 600 and 900 nm [corresponding to a large relative wave number range (~0-4500 cm-1)], with respect to a 632.8 nm excitation and can also acquire images at a fairly narrow band of ~7 cm-1. In this article we describe a confocal surface-enhanced Raman imaging (SERI) system developed in our laboratory that combines hyperspectral imaging capabilities with surface-enhanced Raman scattering (SERS) to identify cellular components with high spatial and temporal resolution. The HSERI system's application to cellular imaging is demonstrated using SERS-labeled nanoparticles in cellular systems. © 2005 American Institute of Physics.
