Novel Nanoparticle Therapy Promotes Wound Healing

An experimental therapy developed by researchers at Albert Einstein College of Medicine of Yeshiva University cut in half the time it takes to heal wounds compared to no treatment at all. Details of the therapy, which was successfully tested in mice, were published online in the Journal of Investigative Dermatology.

ORNL-Led Team Demonstrates Desalination with Nanoporous Graphene Membrane

NatureNanotechPores_img2_FalseColor.jpg

Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy’s Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene—a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

Nanorobotic Agents Open the Blood-Brain Barrier, Offering Hope for New Brain Treatments

Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. The research is important as currently 98% of therapeutic molecules are also unable to cross the blood-brain barrier.

UW Scientists Build a Nanolaser Using a Single Atomic Sheet

University of Washington scientists have built a new nanometer-sized laser using a semiconductor that's only three atoms thick. It could help open the door to next-generation computing that uses light, rather than electrons, to transfer information.

More Research Needed to Clarify Impact of Cellulose Nanocrystals on Health

Maren_1.jpg

Biocompatible and biodegradable, cellulose materials are being studied for use in high-performance composites and optical films, and to deliver medicine in pills. But before a material can be commercialized, its impact on human health must be determined.

Innovative Light Therapy Reaches Deep Tumors

Using a mouse model of cancer, researchers at Washington University School of Medicine in St. Louis have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer. And they accomplished this using materials already approved for use in cancer patients.
