Alternatives to the lithium-ion battery (LIB) become increasingly necessary as the demand for portable electronics, electric vehicles and grid-level energy storage technologies continues to develop. Current Li-ion chemistries are toxic to the environment, highly flammable, and will grow in cost as material needs increase. …. http://nanotechweb.org/cws/article/tech/69562

A two-arm nanorobot that swims in a freestyle stroke when exposed to an oscillating magnetic field has been unveiled by a team of researchers in the US, China and Israel. The new nanoswimmer can propagate through viscous fluids, like those found in the human body, and so could find use in a host of biomedical […]

A new metamaterial nanostructure designed for infrared-based spectroscopy traps 27 times more light than similar devices. Developed by scientists in the US and China, the structure could be used to improve the detection of drugs, bomb-making materials and other chemicals….. http://nanotechweb.org/cws/article/tech/69597

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, […]
