GLCs enable the liquid-phase TEM imaging of biological molecules. The imaging of organic molecules poses an everlasting challenge to transmission electron microscopists, most importantly because of their low electron contrast and sensitivity to the harmful effects of the electron beam. Typical GLCs have a thickness ranging from a few to tens of nanometers, making them ideally transparent to the electron beam. In such pockets, the single molecular resolution imaging of dissolved biopolymers such as DNA and protein chains becomes possible. Highly conductive and a demonstrated radical scavenger, graphene protects your sample against electron beam damage caused by radiolysis, charging or heating. Moreover, as a one atomic layer of carbon, graphene offers minimal obstruction to the electron beam, allowing you to gather maximal information from your sample.
