Is there a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome ...

Free radicals are unstable atoms or molecules with free outer electrons. This makes them highly reactive because free electrons always strive to form a stable bond. This stabilization involves gaining ...

For the first time, researchers have been able to show how a cell closes the door to free radicals – small oxygen molecules that are sometimes needed, but that can also damage our cells. The study is ...
