Stanford's iISM: Revolutionary Label-Free Imaging for Live Cells

3/5/2026

Summary

Story summary

Researchers at Stanford University have developed interferometric Image Scanning Microscopy (iISM), a label-free imaging technique for live cells.
The method avoids photobleaching and phototoxicity by using intrinsic optical signals from cells.
iISM achieves 120 nm lateral resolution without increasing light intensity, enabling faster imaging or reduced exposure.
It integrates with confocal fluorescence microscopy to enable simultaneous label-free and fluorescent imaging.
