DNA does design: 3D plasmonic photonic crystals are the first devices prepared by DNA-guided colloidal crystallization
New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking ...
Researchers develop technique for making light-bending 'raspberry-like metamolecules'
The field of metamaterials is all about making structures that have physical properties that aren't found in nature. Predicting what kinds of structures would have those traits is one challenge; physically ...
'Trojan horse' gold nanoparticles treatment could beat brain tumors
A "Trojan horse" treatment for an aggressive form of brain cancer, which involves using tiny nanoparticles of gold to kill tumour cells, has been successfully tested by scientists.
Researchers find easy way to deposit metal nanoparticles on a surface using tape
Experts create intelligent 'plaster' to monitor patients
Medical engineers said Sunday they had created a device the size of a plaster which can monitor patients by tracking their muscle activity before administering their medication.
Gold nanorods provide whole new way of harvesting energy from the sun
A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert ...
'Mix and match': Mixing nanoparticles to make multifunctional materials
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a general approach for combining different types of nanoparticles to produce large-scale composite materials. The ...
Gold's unexpected oxidation activity: Decoding the role of water in gold nanocatalysis
Researchers from the University of Houston and Trinity University have for the first time provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide.
Engineering team designs 'living materials'
Inspired by natural materials such as bone—a matrix of minerals and other substances, including living cells—MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving ...
Researchers create nanoparticle thin films that self-assemble in one minute
The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...
Nano-scale gold particles are good candidates for drug delivery
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
Mice study enables view of nanoparticle accumulation
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 ...
