Latest Janus particles Stories
In what they are calling a step towards building microscopic robots, researchers from the University of Michigan have demonstrated how chains of self-assembling particles could act like tiny, electrically-activated muscles.
Janus capsules, miniature hollow and fragmented structures composed of different micro- and nanoparticles, have long been theorized with scientists able to design models but finding themselves challenged on the actual production of them.
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.
Researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.
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.
The use of nanomaterials for water treatment, food packaging, pesticides, cosmetics and other industrial uses has increased over the last few years. In regards to use in food packaging, these nanoparticles may also be entering our bodies through food consumption.
In recent years, metal nanoparticles have showed great application prospect in the field of biological imaging, cancer diagnosis and treatment due to its unique optical scattering and optical absorption properties.
In a new study performed at the Center for Nanoscale Materials at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers have for the first time seen the self-assembly of nanoparticle chains in situ, that is, in place as it occurs in real-time.
By modifying the rate at which chemical reactions take place, nanoparticle catalysts fulfill myriad roles in industry, the biomedical arena and everyday life.
New drug delivery systems, solar cells, industrial catalysts and video displays are among the potential applications of special particles that possess two chemically distinct sides.
- An uxorious, effeminate, or spiritless man.
- A timorous, cowardly fellow.
