Better RNA interference, inspired by nature: New nanoparticles offer best-ever gene silencing
Inspired by tiny particles that carry cholesterol through the body, MIT chemical engineers have designed nanoparticles that can deliver snippets of genetic material that turn off disease-causing genes.
Cells prefer nanodiscs over nanorods
For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into ...
Biomolecular tweezers facilitate study of mechanical force effects on cells and proteins
A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices – too small to see without a microscope – use ...
Surface characteristics influence cellular growth on semiconductor material
(Phys.org) —Changing the texture and surface characteristics of a semiconductor material at the nanoscale can influence the way that neural cells grow on the material.
Nanoparticles target anti-inflammatory drugs where needed
Researchers at the University of Illinois at Chicago have developed a system for precisely delivering anti-inflammatory drugs to immune cells gone out of control, while sparing their well-behaved counterparts. ...
New technique allows "nanobiopsies" of living cells
(Phys.org) —Researchers at UC Santa Cruz have developed a robotic "nanobiopsy" system that can extract tiny samples from inside a living cell without killing it. The single-cell nanobiopsy technique is ...
Nanodiamond-embedded contact lenses may improve glaucoma treatment
(Phys.org) —By 2020, nearly 80 million people are expected to have glaucoma, a disorder of the eye that, if left untreated, can damage the optic nerve and eventually lead to blindness.
Toxic nanoparticles might be entering human food supply, study finds
Over the last few years, the use of nanomaterials for water treatment, food packaging, pesticides, cosmetics and other industries has increased. For example, farmers have used silver nanoparticles as a pesticide ...
Researchers figure out why gold nanoparticles can penetrate cell walls
Cells are very good at protecting their precious contents—and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective ...
Researchers generate electricity from viruses
Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy's Lawrence ...
'Zombie' replica cells may outperform live ones as catalysts and conductors
(Phys.org)— "Zombie" mammalian cells that may function better after they die have been created by researchers at Sandia National Laboratories and the University of New Mexico (UNM).
Biomimetic nanosponges absorb toxins released by bacterial infections and venom
Engineers at the University of California, San Diego have invented a "nanosponge" capable of safely removing a broad class of dangerous toxins from the bloodstream – including toxins produced by MRSA, E. co ...
