A team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer’s and Parkinson’s Diseases. The biosensor can also transmit the results wirelessly.
A new device could monitor and treat heart disease and dysfunction in the days, weeks or months following traumatic heart-related events — and harmlessly dissolve afterwards.
Researchers at the University of Campinas and the Federal University of São Carlos in Brazil have developed an electrochemical sensor that detects Parkinson's disease at different stages.
US scientists report using a single-atom-thick nanomaterial to simultaneously detect Covid-19 and flu viruses — at much lower levels and much more quickly than conventional tests for either.
Blood pressure is one of the most basic parameters in any healthcare status assessment and holds considerable diagnostic significance. However, clinicians should never underestimate the complexity behind the assessment, cautions Dr Rhian M. Touyz.
A project to develop advanced sensors for use in robotic systems could transform prosthetics and robotic limbs. It aims to develop sensors which provide enhanced capabilities to robot.
Of all the methods used in identity and access management (IAM), biometrics is arguably the oldest: it has been around long before IAM was a “thing”. Humans are naturally optimized for recognizing fellow humans’ faces, voices and other biometric features. However, even biometric recognition between humans is less than perfect, as countless cases of successful impersonators and impostors…
Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers consist of 90 percent water, are elastic and particularly biocompatible. Hydrogels that are also electrically conductive allow additional fields of application, for example in the transmission of electrical signals…
Stevens Institute of Technology has signed an exclusive licensing agreement with Bonbouton, giving the company the right to use and further develop a graphene sensing system that detects early signs of foot ulcers before they form, so diabetic patients can access preventative healthcare and manage their health.
Researchers have created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders.
Stretchable electronics is emerging as a promising new technology for next-generation wearable devices, according to a review published in Science and Technology of Advanced Materials. The technology has many possible applications for healthcare, energy and the military. But there are several challenges involved in finding suitable materials and manufacturing methods. The biggest challenge for…
A team led by the University of California San Diego has developed a chip that can detect a type of genetic mutation known as a single nucleotide polymorphism (SNP) and send the results in real time to a smartphone, computer, or other electronic device. The chip is at least 1,000 times more sensitive at detecting an SNP than current technology. The advance could lead to cheaper, faster and…
Cell-based biosensors can simulate the effect of various substances, such as drugs, on the human body in the laboratory. Depending on the measuring principle, though, producing them can be expensive. As a result, they are often not used. Cost factors for sensors that perform measurements electrically are the expensive electrode material and complex production. Fraunhofer scientists are now…
Cancer thrives when mutated cells undergo frequent division. Most anti-cancer drugs work by inserting themselves in between the DNA base pairs that encode our genetic information. This process is known as intercalation, and it can result in subtle changes to the DNA molecule’s geometric shape or tertiary structure. These structural changes interfere with the DNA’s transcription and a cell’s…
The Universities of Exeter and Bath (UK) have revealed their plans for a new world-leading research centre to explore and exploit the properties of the thinnest material in nature. The two universities have won a £5 million Science and Innovation Award from the Engineering and Physical Sciences Research Council (EPSRC) to create the Centre of Graphene Science.
