What to know about Single-step 8-9x expansion reveals nanoscale centrioles without electron microscopy

Researchers from National Taiwan University have developed a new expansion microscopy strategy called hiHomoExM that allows for 8-9x isotropic expansion of biological samples. This method, especially when combined with dSTORM, enables the visualization of nanoscale centriole structures using optical microscopy instead of electron microscopy.

What happened

Single-step 8-9x expansion reveals nanoscale centrioles without electron microscopy Lisa Lock Scientific Editor Robert Egan Associate Editor In a study published in ACS Nano, researchers from National Taiwan University report a new expansion microscopy…

Why it matters

Expansion microscopy works by embedding biological samples within a swellable polymer hydrogel.

Common ground

Following chemical processing, the hydrogel expands uniformly in water, physically separating biomolecules and effectively increasing the spatial resolution achievable by conventional light microscopes.
