Chemical Imaging Microscopy for Optical Biothreat Detection

Cryoimaging-Microscopy Implementation for 3D Optical Imaging

Optical lock-in detection imaging microscopy for contrast-enhanced imaging in living cells.

One of the limitations on imaging fluorescent proteins within living cells is that they are usually present in small numbers and need to be detected over a large background. We have developed the means to isolate specific fluorescence signals from background by using lock-in detection of the modulated fluorescence of a class of optical probe termed "optical switches." This optical lock-in detec...

Imaging without fluorescence: nonlinear optical microscopy for quantitative cellular imaging.

Quantitative single-cell analysis enables the characterization of cellular systems with a level of detail that cannot be achieved with ensemble measurement. In this Feature we explore quantitative cellular imaging applications with nonlinear microscopy techniques. We first offer an introductory tutorial on nonlinear optical processes and then survey a range of techniques that have proven to be ...
