Smiths Detection, a global leader in threat detection and security screening technologies, today reports that its BioFlash® Biological Identifier is capable of detecting SARS-CoV-2 in the air following tests conducted by the United States Army Medical Research Institute of Infectious Diseases (USAMRIID).
Researchers at Linköping University, Sweden, have developed biosensors that make it possible to monitor sugar levels in real time deep in the plant tissues - something that has previously been impossible. The information from the sensors may help agriculture to adapt production as the world faces climate change. The results have been published in the scientific journal iScience.
Photoplethysmography (PPG) is an easy optical method for detecting volumetric variations in peripheral blood circulation.
Some promising biosensors and medical devices work well within pristine laboratory environments. However, they tend to stop working to deliver medical therapeutics or monitor chronic health issues once exposed to the real-world conditions of complex biological fluids.
A new method has been developed by researchers to detect the proteins that constitute the pandemic coronavirus, along with its antibodies. They created protein-based biosensors that glow on combining with components of the virus or particular COVID-19 antibodies.
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.
