Stick a soda straw into a glass of water, and from the side, the straw will appear to bend at the interface between air and water. That effect is caused by the different refractive indexes of the air ...
In recent years, Total Internal Reflection Fluorescence (TIRF) microscopy has become an important method for studying molecular interactions near the cell surface. To accommodate the trend of the ...
TIRF microscopy uses the principle of total internal reflection to selectively activate fluorophores near the slide-sample interface while ignoring more deeply embedded ones. That makes the technique ...
