A new technique in microscopy developed by Moore Foundation grantee, Mark Kasevich and his students at Stanford, enables light-sensitive samples to be seen more clearly through a microscope without damage. This is an important advance because currently researchers image proteins and living cells in low light to avoid damaging the fragile samples, which results in grainy pictures and makes it hard to distinguish the intricate proteins and internal structures they are trying to study.
The effect that causes grainy images of either your meal or a biological sample is called shot noise. Stanford researchers may have come up with an elegant solution to this problem, which they refer to as “multi-pass microscopy.” This technique, detailed in a paper published in the open-access journal Nature Communications, could make it possible to view proteins and living cells in greater clarity than ever before.
