An Introduction to Fluorescence Imaging

Imaging microscopic biological specimens demands greater resolution than can typically be attained via conventional microscopy. Consider a cell, which is predominantly composed of water and is subsequently transparent. Visible light-based microscopy will fail to provide much detail about cellular structures, as most light on the range of 400–700 nanometers (nm) will simply transmit through. This … Continue reading

Brillouin Light Scattering Microscopy Used in Cytoskeletal Research

A recent article in “Nature,” entitled “Cytoskeletal disorganization underlies PABPN1-mediated myogenic disability” suggests that “poor cytoskeletal mechanical features are caused by altered expression levels of cytoskeletal proteins and contribute to muscle wasting and atrophy.” This research involved Brillouin light scattering microscopy using a home-built Brillouin confocal microscope. A single mode torus 532 nm laser from … Continue reading
