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 develop holography technology that could change the way we view the world
Since the 1960s, theatergoers have shelled out for crude 3-D glasses, polarized glasses, and shutter glasses to enhance their viewing experience. These basic devices, used to trick the brain into perceiving an artificial ...
Graphene multiplies the power of light
Could graphene turn light to electricity? Scientists have shown that graphene can convert a single photon into multiple electrons, showing much promise for future photovoltaic devices.
