Nanotechnology has been hailed as the next big thing for decades, but it is only now that it is truly becoming a reality in the medical device space. The term nanotechnology itself dates back to the 1980s, when it was coined by U.S. engineer Eric Drexler. In the past few decades, nanotech has found a […]
Taiwan FDA conducted sample inspections of marketed cosmetics. 20 unregistered medicated cosmetics and 20 imported cosmetics without approval were discovered. Severe punishments were handed out. According to the “Statute for Control of Cosmetic Hygiene (2002)”, anyone who sells/distributes unregistered medicated cosmetics would be subject to 1 year term of detention and imprisonment and/or fined up […]
At one time you could wander through the labs of pharmaceutical companies and hardly ever see light being used to mediate chemical reactions. Now “photoredox catalysis” has become an essential way to synthesize novel organic compounds……. https://nano-magazine.com/news/2017/5/29/light-emitting-quantum-dots-could-ease-synthesis-of-novel-compounds
The shells of marine organisms take a beating from impacts due to storms and tides, rocky shores, and sharp-toothed predators. But as recent research has demonstrated, one type of shell stands out above all the others in its toughness: the conch….. https://nano-magazine.com/news/2017/5/27/conch-shells-spill-the-secret-to-their-toughness
Researchers working at CQT and Caltech have discovered that all entangled states of two particles have a classical fingerprint. This breakthrough could help engineers guard against errors and devices that don’t do what they promise in quantum computing and quantum cryptography……. https://nano-magazine.com/news/2017/5/30/quantum-states-reveal-themselves-with-measurable-fingerprint
Heterostructures based on 2D layered semiconductors such as gallium selenide (GaSe) and conventional 3D semiconductors such as gallium nitride (GaN) could be used to make novel, high-performance electronics and optoelectronics devices. However, such devices will require high-quality materials at the wafer scale with excellent crystalline order and sharp interfaces. A team of researchers at The […]
Researchers at the University of Virginia and Johns Hopkins University School of Medicine in Baltimore have developed a new, non-invasive and non-toxic genetic therapeutic technique to restore dopaminergic neuron function in rats suffering from Parkinson’s disease. The technique, which makes use of magnetic-resonance-image-guided ultrasound and brain-penetrating nanoparticles, reverses neurodegeneration thanks to expression of the neurotrophic […]
Radiation therapy is a highly effective treatment for localized cancers, but can be limited by the inherent resistance of some cancer cells to ionizing radiation. Attempts to improve outcomes have largely focused on increasing delivered dose, sensitizing resistant tumour cells or developing targeted therapies. Speaking at the recent ESTRO 36 in Vienna, Sunil Krishnan from […]
With our persistent march towards nuclear fusion, the need for technologies that can operate in high-energy environments is becoming ever more urgent. Now, researchers in the UK and Spain have discovered a material that can allow us to take pictures inside a nuclear reactor…. http://nanotechweb.org/cws/article/tech/68875
“Thermally activated delayed fluorescence” (TADF) materials are promising for a number of applications ranging from imaging and security, to solar cells and light-emitting diodes and the pixels used in flat panel displays. However, most of the TADF materials made so far are based on metal-organic complexes and organic molecules that have lifetimes of only several […]
Researchers at Columbia University in New York have observed a Bose-Einstein condensate of excitons in the quantum Hall regime in a double bilayer graphene heterostructure. Such a system is thought to host an excitonic analogue of the superconducting state at high temperature and zero magnetic field and so could be used to study strongly interacting […]
The sun is a good source of Vitamin D which is very important to the body. On the other hand, overexposure to the heat of the sun can lead to skin cancer. Thus, doctors advise people to put on some sunscreen for protection. Recently, nanotechnologists have developed a sunscreen that produces melanin…… https://nano-magazine.com/news/2017/5/24/scientists-created-a-sunscreen-that-produces-melanin
Nanolabs, a company specialised in nanotechnology, has been able to increase the production of melons by up to 40% on a farm in Almeria, thanks to the installation of ASAR systems in the irrigation system of the farm…….. https://nano-magazine.com/news/2017/5/18/up-to-40-more-melons-thanks-to-nanotechnology
A plant grower from the UK has helped grow what is believed to be the world’s hottest chilli pepper, after “introducing nanofeed into the plant”….. https://nano-magazine.com/news/2017/5/22/worlds-hottest-chilli-pepper-grown-using-nanofeed
The simplicity of “bottom up” self-assembly has long vied with the extreme control of more painstaking “top down” lithography techniques for nanofabrication. Now the self-assembly of reproducible arrays of flat spirals—where even the chirality of the structures can be controlled by design—has demonstrated not just the impressive level of control that can be achieved using […]
A team of researchers in Israel has made a bipedal motor from DNA that can be controlled using a computer-based microfluidics-based interface. The molecular machine, which can “walk” on a DNA origami track in response to DNA fuel and anti-fuel strand commands, might find use in nanotechnology applications such as next-generation nanomachines and “nanofactories” for […]
