Fluorescence microscopy in a microwave cavity

Optical microscopy is a well-established technique that has wide ranging applications for imaging molecular dynamics of biological systems. Typically, these applications rely on external temperature controllers to maintain or change reactions rates of these biological systems. With increasing interest in applying low power microwaves to drive biological and chemical reactions, we have combined optical and microwave based technologies and developed a fluorescence microscope in a microwave cavity. With this instrument, we have found a means to optically image biological systems inside microwave cavities during the application of microwave pulses.
