Scientists have improved cancer treatments in recent years by combining radiation therapy with immunotherapy. Now, researchers in the US and China have engineered nanoparticles to improve outcomes further. The nanoparticles capture tumour-derived proteins at the treatment site, providing a kick to the immune system and enabling it to detect and respond to cancer cells elsewhere […]
Circulating foetal nucleated cells (CFNCs) in the blood of pregnant women is an ideal source of foetal genomic DNA that can be used for prenatal diagnostics. However, the problem is that there are only a very small number of CFNCs in maternal blood….. http://nanotechweb.org/cws/article/tech/69609
Quasi-random photonic nanostructured surfaces are ideal for optoelectronics applications such as photovoltaics because they can manipulate light over broad wavelengths and a wide range of angles. ….. http://nanotechweb.org/cws/article/tech/69610
The peculiar behaviours of structures at the nanoscale allow applications that would be impossible for devices fabricated at the macro- or even merely microscale. But engineering at this scale also brings its own set of problems….. http://nanotechweb.org/cws/article/tech/69644
Computers that fit in our pockets, television screens no thicker than a door, and cars only slightly bigger than their passengers, technology is constantly getting smaller. A major reason for this miniaturization is the development of nano-size resonators, which convert small levels of electrical power into mechanical oscillations at high frequencies….. https://nano-magazine.com/news/2017/7/31/metal-instability-achieves-energy-efficient-nanotechnology
Researchers at the Hebrew University of Jerusalem’s Center for Nanoscience and Nanotechnology have developed a new type of photoinitiator for three-dimensional (3D) printing in water. These novel nanoparticles could allow for the creation of bio-friendly 3D printed structures, further the development of biomedical accessories, and drive progress in traditional industries such as plastics….. https://nano-magazine.com/news/2017/8/1/3-d-printing-in-water-opens-door-to-advanced-biomedical-materials
More than 844 million people around the globe lack access to clean water. One of the challenges is that bacteria from rivers can flow into groundwater sources, polluting what may have been potable drinking water. Building new infrastructure to reroute clean water is expensive, especially for regions that already struggle with extreme poverty. Instead, communities […]
Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells. Researchers from MIT and other institutions are hoping to use nanotechnology to develop more targeted treatments for these drug-resistant bugs. […]
Researchers at the Australian National University have designed a new silicon-based dielectric nanomaterial whose refractive index can be changed with temperature so that it either reflects or transmits light. The metasurface could be used in a host of applications in the emerging field of “flat optics”….. http://nanotechweb.org/cws/article/tech/69472
Researchers at Harvard University have developed a new way to measure spin chemical potential (or spin voltage) in materials using a magnetometer made from atomic-sized defects in diamond. The technique could help in the development of spintronics devices, such as spin transistors and spin gates, which exploit the spin of electrons rather than their charge, […]
A team of scientists from the UK and China has for the first time observed Fermi arcs – a distinct signature of the presence of topological properties – in a microwave metamaterial. Recent experiments have revealed Fermi arcs in quantum matter, but this is the first time they have been seen in a classical 3D […]
In recent years researchers have succeeded in making ultrathin health-monitoring “patches” comprising electronics devices that can be directly applied to skin. However, such wearable electronics are often rigid and do not allow skin to breathe. A team of scientists in Japan has now overcome this problem with its new gas-permeable and stretchable on-skin sensor made […]
Thanks to a technique called hard X-ray magnetic tomography, researchers at the Paul Scherrer Institute (PSI) in Switzerland, the ETH Zurich and the University of Glasgow have succeeded in imaging the magnetization in 3D bulk-like magnets and observe features down to just 100 nm. In particular, they have observed structures known as Bloch points, which […]
Japanese scientists have developed a hypoallergenic electronic sensor that can be worn on the skin to monitor a person’s health continuously over a long period. The wearable device, that can be worn for a week without discomfort, has elastic electrodes, made up of breathable nanoscale meshes, that lets the skin breathe, preventing inflammation…….. https://nano-magazine.com/news/2017/7/17/new-wearable-e-skin-sensor-to-boost-health-monitoring
For more than 20 years, marine biologist Mary Hagedorn faced a seemingly intractable problem. She was looking for a way to freeze and defrost the embryos of zebrafish…… https://nano-magazine.com/news/2017/7/13/freezing-and-unfreezing-zebrafish-embryos-using-nanotechnology-and-lasers
Unlike most 11-year-olds, Gitanjali Rao likes to spend some of her free time reading MIT’s material science department website. That’s where Rao learned about a recently-developed type of nanotechnology–and realized that it could be used for a new purpose…… https://nano-magazine.com/news/2017/7/13/this-11-year-old-invented-a-cheap-test-kit-for-lead-in-drinking-water
Nature Communications has recently published a report on the development of an ultrafast tunable metamaterial, based on gallium arsenide nanoparticles, by an international team of Researchers from Moscow State University (Russia), Sandia National Laboratories in Albuquerque (USA) and Friedrich-Schiller University in Jena (Germany). ….. http://www.azom.com/news.aspx?newsID=47715
In an effort to combine graphene and nanoparticles, two of the most sought-after and popular technologies available today, a team of scientists from the Department of Chemical Engineering University of Illinois at Chicago have developed a revolutionary synthesis method that enhances the phenomenal properties of these materials without any need to compromise the unique properties […]
Surface-enhanced Raman scattering (SERS) nanoparticles are setting themselves to be an attractive alternative to fluorescent probes in biological labeling applications, due to their photostability and multiplexing capabilities. …. http://www.azonano.com/article.aspx?ArticleID=4557
The process of synthesizing nanoparticles is mostly trial and error, even though Scientists have been able to synthesize nanoparticles in the lab for decades, and it is still difficult to understand how the formation actually takes place. However, an explanation on how metal nanoparticles form has been presented by Chemical Engineers at the University of […]
An international team in which a UPM researcher is involved has shown that it is possible to mechanically destroy cancer cells by rotating magnetic nanoparticles attached to them in elongated aggregates…. http://www.azonano.com/news.aspx?newsID=35638
