A team of Penn State researchers has developed a biomimetic nanosystem to deliver therapeutic proteins to selectively target cancerous tumors. Using a protein toxin from a plant found in the Himalayan mountains, called gelonin, the researchers caged the proteins in self-assembled metal-organic framework (MOF) nanoparticles to protect them from the body’s immune system. To enhance…

The “clean-energy economy” always seems a few steps away but never quite here. Fossil fuels still power transportation, heating and cooling, and manufacturing, but a team of scientists from Penn State and Florida State University has come one step closer to inexpensive, clean hydrogen fuel with a lower cost and industrially scalable catalyst that produces…

Some researchers are working to discover new, safer ways to deliver cancer-fighting drugs to tumors without damaging healthy cells. Others are finding ways to boost the body’s own immune system to attack cancer cells. Researchers at Penn State have combined the two approaches by taking biodegradable polymer nanoparticles encapsulated with cancer-fighting drugs and incorporating them…

Researchers at Penn State, the Department of Energy’s Oak Ridge National Laboratory, and Lockheed Martin Space Systems Company have developed methods to control defects in two-dimensional materials, such as graphene, that may lead to improved membranes for water desalination, energy storage, sensing, or advanced protective coatings. For a two-dimensional, one-atom-thick material like graphene, defects such…

A newly discovered method for making two-dimensional materials could lead to new and extraordinary properties, particularly in a class of materials called nitrides, say the Penn State materials scientists who discovered the process. This first-ever growth of two-dimensional gallium nitride using graphene encapsulation could lead to applications in deep ultraviolet lasers, next-generation electronics, and sensors.…
