In a paper published in NANO, researchers from Hubei, China discuss the top-down and bottom-up strategies for the synthesis of Graphene quantum dots (GQDs). The respective advantages and disadvantages of these methods are summarized.
Viral respiratory diseases are easily transmissible and can spread rapidly across the globe, causing significant damage. The ongoing covid-19 pandemic is a testament to this. In the past too, other viruses have caused massive respiratory disease outbreaks: for example, a subtype of the influenza virus, the type A H1N1 virus, was responsible for the Spanish flu and the Swine flu outbreaks.
( Kanazawa University ) Researchers at Kanazawa University report in Communications Chemistry that a molecule known as pillar[6]arene can form a host-guest compound with a cancer-associated metabolite. The phenomenon can be used to efficiently detect the metabolite in crude biological samples, which is important for preventing and treating metabolic syndrome and associated pathologies.
Imagine typing on a computer without a keyboard, playing a video game without a controller or driving a car without a wheel.
For over ten years, Ali Yanik has been working to develop novel biosensor technology to provide rapid, low-cost testing for disease diagnostics and precision medicine.
Scientists have designed a novel living plant-based sensor that can detect and track arsenic levels in the soil in real time.
Scientists from Disruptive & Sustainable Technologies for Agricultural Precision (DiSTAP), an Interdisciplinary Research Group (IRG) at the Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, have engineered a novel type of plant nanobionic optical sensor that can detect and monitor, in real-time, levels of the highly toxic heavy metal arsenic in the belowground environment.
Associate Professor Kazuhiro Takahashi and Assistant Professor Yong-Joon Choi of the Department of Electrical and Electronic Information Engineering at Toyohashi University of Technology have developed a chip that can sense antigens at one part per quadrillion molar mass.
Researchers from Bochum, Göttingen, Duisburg and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods.
A material with the ability to mimic the human skin in terms of sensitivity, stretchability, and strength could help collect biological information in real time.
