Cancer-killing nanoparticles sneak through defenses camouflaged in tumor cells

Michael Irving June 19, 2018

A new therapy designed at Penn State has turned one of cancer's tactics against it. The team camouflaged a cancer-killing drug using cells from the tumor itself, allowing them to sneak medicine past the tumor’s defenses like a nanoscale Trojan horse and deliver a killing blow from the inside.

Magnetic nanoparticles designed to stop internal bleeding

Ben Coxworth March 5, 2018

Major internal bleeding is a very serious condition that requires immediate attention, and it's difficult to treat non-surgically. Scientists from Russia's ITMO University are working on an effective means of doing so, however, in the form of injectable magnetic nanoparticles.

Clot-busting skin patch keeps the blood flowing with microneedles

Michael Franco November 28, 2016

According to the CDC, every year 60,000-100,000 people die in the US alone from blood clots formed from conditions known as deep vein thrombosis or pulmonary embolisms. Now, a new patch developed by researchers in North Carolina could help battle these life-threateners in a novel way.
