Scanning electron microscope (left) being used by two scientists to study mites. Mites have traditionally been difficult to study because of their small size, which is sometimes only 80 micrometres across. This means it is difficult to study closely the mites' tiny structures using a light microscope. Low-temperature scanning electron microscopy (LT-SEM), which uses liquid nitrogen to freeze the mites before forming an image using electrons and a magnetic field, generates images of much higher magnification and accuracy.
