To improve our understanding of biomolecular processes happening within cells, techniques for visualizing and recording them are of key importance. High-speed atomic-force microscopy (HS-AFM) has become an important technique for the real-time observation of biological processes on the sub-molecular spatial scale and with sub-second time resolution. Still, a higher video frame rate is required for recording many important processes, such as ion transport motion or signaling mechanisms within membranes. Now, Kenichi Umeda, Toshio Ando and Noriyuki Kodera from Kanazawa University and colleagues have designed an amplitude detector with ultrafast operation, the use of which in HS-AFM leads to a significantly improved temporal resolution.
