Live cell imaging technique with increased contrast and penetration depth
Non-invasive, live cell imaging is critical to modern biological and medical research. Two-photon fluorescence microscopy is an important method used to visualize tissue in depth. However, it suffers from constraints on image contrast because of out-of-focus fluorescence that overwhelms the detected signal. This technology proposes a method to extend the depth limit and increase contrast by performing stimulated emission reduced fluorescence microscopy (SERF). The subsequent reconstructed image using this method has a significantly improved signal-to-background contrast. This allows for improved depth and resolution of two-photon fluorescence microscopy for live cell imaging of biological specimens including brain slices, embryos, whole organs, and even live animals.
