It could replace the traditional refractive lenses that we have today A Northwestern University research team has developed tiny optical elements from metal nanoparticles and a polymer that one day could replace traditional refractive lenses to realize portable imaging systems and optoelectronic devices.

Implant to better track brain chemical gone rogue after neurotrauma

03.28.2019 09:23 AM

Your chances of getting a nasty migraine increase following a spinal cord injury, thanks to a chemical messenger in the brain that spikes to toxic levels, past studies have suggested.

Nanovaccine boosts immunity in sufferers of metabolic syndrome

03.28.2019 09:13 AM

A new class of biomaterial developed by Cornell researchers for an infectious disease nanovaccine effectively boosted immunity in mice with metabolic disorders linked to gut bacteria – a population that shows resistance to traditional flu and polio vaccines.

Should Technology Be Used to Extend the Human Lifespan?

03.28.2019 08:49 AM

Technology may be able to ‘hack’ human mortality. In light of rapid gains in gene editing, nanotechnology, and robotics, some futurists expect this generation's biohackers to double their life spans.

Metal nanoclusters can be used as semiconductors: Key properties observed for first time

03.27.2019 08:21 AM

Tiny nanoclusters of metal atoms—such as gold and silver—have properties which mean they can be used as semiconductors, a joint Swansea-Hamburg research team has discovered.

Layered liquids arrange nanoparticles into useful configurations

03.27.2019 07:45 AM

Researchers have created a new "oil and vinegar" approach to forming nanoparticle structures. In this conceptual model, green and blue elements repel one another. Not only does this create a boundary layer where particles tend to congregate, researchers can attach molecules to individual nanoparticles to make them more or less repulsed by an individual layer.

Computer scientists create reprogrammable molecular computing system

03.26.2019 08:32 AM

Researchers have designed self-assembling DNA molecules with unprecedented reprogrammability. Computer scientists at Caltech have designed DNA molecules that can carry out reprogrammable computations, for the first time creating so-called algorithmic self-assembly in which the same "hardware" can be configured to run different "software.

Nanoscale patterning could enable precise manipulation of objects on many scales

03.26.2019 08:31 AM

Specially designed materials enable objects of different sizes to be levitated and manipulated with light, thanks to new research.

New membrane class shown to regenerate tissue and bone

03.24.2019 11:44 AM

A multifunctional periodontal membrane is surgically inserted into the pocket between affected gums and tooth. This new membrane has shown to protect the site from further infection as well as to help regrow bone

Nanotechnology: Speeding Up the Healing Process

03.23.2019 12:48 PM

Nanotech-infused bandages could potentially heal you faster. Egyptian researchers have developed a bandage infused with nanoparticles for the treatment of wounds using the anti-epilepsy drug Phenytoin, known for its capacity to treat skin injuries.

Chemicals induce dipoles to damp plasmons

03.23.2019 11:16 AM

The light scattered by plasmonic nanoparticles is useful, but some of it gets lost at the surface and scientists are now starting to figure out why.

Making solar cells is like buttering bread

03.22.2019 15:10 PM

The 2D films based on 2-phenylethylammonium lead iodide produce 3D formamidinium lead iodide films via cation exchange

Researchers from NIST boost intensity of nanowire LEDs

03.21.2019 16:57 PM

Nanowire gurus at the National Institute of Standards and Technology (NIST) have made ultraviolet light-emitting diodes produce five times higher light intensity than do comparable LEDs

Neon tetra fish inspired material changes colors using nanocolumns

03.20.2019 13:08 PM

Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material.

Researchers created a sensor to detect brain disorders

03.19.2019 20:37 PM

Using nanotechnology, UCF researchers have developed the first rapid detector for dopamine, a chemical that is believed to play a role in various diseases such as Parkinson's, depression and some cancers.
