  Originally published by Kanazawa Universit at www.phys.org, on September 5, 2023 Overview of the method for observing actin fibers in living cells using nanoendoscopy-AFM. Credit: STAR Protocols (2023). DOI: 10.1016/j.xpro.2023.102468 Images of nanoscale structures inside living cells are in increasing demand for the insights into cellular structure and function that they can reveal. So far, the tools for capturing such images have been limited, but researchers led by Takeshi Fukuma and Takehiko Ichikawa at Kanazawa University have now devised and reported a full protocol for using atomic force microscopy (AFM) to image inside living cells . The research is published in the journal STAR Protocols . AFM was first developed in the 1980s and uses the changes in the forces between a sample surface and a nanoscale tip attached to a cantilever to identify surfaces and produce images of the topography with nanoscale resolution. The technique has grown increasingly sophisticated
