They performed a catalase assay to determine the cells’ response to oxidative stress. E. coli produce the catalase enzyme to protect themselves against oxidative stress.

We all get gray hair at some point. While some people wear it with pride, others would like to delay its appearance as long ...

Enzymes, the core catalysts in life, drive critical biological processes ranging from metabolic regulation to energy conversion. Evolved over billions of years, these versatile molecular machines not ...

Researchers attached catalase enzymes - biological catalyst that speed up the rate of chemical reactions in cells - to the bots.

Tiny, enzyme-powered "snot bots" can push through the sticky defensive mucus layer, helping to deliver drugs more efficiently.

And now, researchers have demonstrated in mice that their tiny, enzyme-powered 'snot bots' can push through the defensive, sticky layer and potentially deliver drugs more efficiently.

Researchers reporting in ACS Nano have designed tiny, enzyme-powered, mucus-busting “snot bots” that can help deliver drugs to some sticky parts of the body.

To build the nano-sized robots (10 of them lined up would span a red blood cell), researchers attached catalase enzymes to porous silica nanoparticles.
