A team of researchers at the University of Pittsburgh has developed a skin patch that can detect antibodies associated with COVID and flu infections. It's orders of magnitude more sensitive than existing tests, uses just a half volt of electricity, and can return results in 10 minutes. https://medicalxpress.com/news/2025-11-needle-flucovid-vaccines-effective.html Mon, 10 Nov 2025 14:14:02 EST news682006441 In the COVID-19 pandemic era, at-home, portable tests were crucial for knowing when to wear a mask or isolate at home. Now, Penn State engineering researchers have developed a portable and wireless device to simultaneously detect SARS-CoV-2, the virus that causes COVID-19, and vitamin C, a critical nutrient that helps bolster infection resistance, by integrating commercial transistors with printed laser-induced graphene. https://medicalxpress.com/news/2025-01-biosensing-platform-simultaneously-vitamin-sars.html Tue, 21 Jan 2025 17:12:04 EST news656701921 An international 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 to a laptop or smartphone. https://medicalxpress.com/news/2023-11-wireless-handheld-non-invasive-device-alzheimer.html Mon, 13 Nov 2023 15:00:02 EST news619090330 Gastric cancer is one of the most common cancers worldwide. A new invention by researchers from the National University of Singapore (NUS) could help improve the treatment of this cancer by enhancing the precision of radiotherapy, which is commonly used in combination with treatment options such as surgery, chemotherapy or immunotherapy. https://medicalxpress.com/news/2023-04-ingestible-capsule-x-ray-dosimeter-real-time.html Fri, 14 Apr 2023 09:32:17 EDT news600683529 Anyone familiar with antidepressants like Prozac or Wellbutrin knows that these drugs boost levels of neurotransmitters in the brain like serotonin and dopamine, which are known to play an important role in mood and behavior. https://medicalxpress.com/news/2022-12-soft-brain-probe-boon-depression.html Mon, 19 Dec 2022 13:31:04 EST news590679062 Having biopsies taken and endless tests run is nobody's idea of a good time, even if it's necessary for monitoring your health. Now, researchers from Japan report the development of a new technique that could make testing for cancer a lot less invasive. https://medicalxpress.com/news/2022-10-transistors-cancer-cell-markers.html Mon, 31 Oct 2022 11:13:03 EDT news586433581 With any highly infectious disease, time can be a killer. https://medicalxpress.com/news/2022-04-highly-accurate-second-coronavirus.html Thu, 07 Apr 2022 14:04:34 EDT news568559070 Scientists have successfully tested in the lab a tiny biosensor they developed that can detect biomarkers tied to traumatic brain injuries. https://medicalxpress.com/news/2022-02-scientists-biosensor-aimed-brain.html Thu, 03 Feb 2022 09:21:32 EST news563102488 In the past 20 years, humans have suffered several serious epidemics from emerging viruses, such as SARS, swine flu, Ebola, MERS and (most recently) SARS-CoV-2. During each epidemic, an accurate, rapid, and accessible molecular diagnostic test is highly essential for the control and prevention of viral diseases. In particular, coronavirus disease 2019 (COVID-19) is spreading rapidly in most countries, resulting in a severe global pandemic, which has a profound impact on the world economy and people's normal life. Accurate and rapid diagnosis of COVID-19 has been the most crucial measure for controlling the ongoing pandemic. In general, reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) is the primary method for detection of nucleic acid-based genetic sequences. Because of the labor-intensive sample preparation, which must be conducted in a biological laboratory by professionals using specialized instruments, the typical turnaround time of the RT-qPCR method is longer than 24 hours. In addition, the complex RT-qPCR process might also reduce clinical sensitivity, resulting in false negative results. https://medicalxpress.com/news/2021-01-fast-sars-cov-.html Mon, 25 Jan 2021 16:21:38 EST news530814086 Electromagnetic radiation (EMR) exposure from the sun and artificial lighting systems represent a health risk, therefore personalized methods for EMR dosimetry can guide people toward lifestyle behaviors that ensure healthy levels of exposure. In a recent report on Science Advances, Kyeongha Kwon and a research team in the departments of Biomedical Engineering, Statistics, Electronics Convergence Engineering and the Center for Advanced Regenerative Engineering in the U.S. and Korea developed a millimeter-scale, ultra-low-power digital dosimeter platform. https://medicalxpress.com/news/2020-01-miniaturized-light-adaptive-wireless-dosimeters-autonomously.html Fri, 03 Jan 2020 08:00:01 EST news497253939 Researchers have developed a three-dimensional 'organ on a chip' which enables real-time continuous monitoring of cells, and could be used to develop new treatments for disease while reducing the number of animals used in research. https://medicalxpress.com/news/2018-10-3d-chip-disease-treatments.html Fri, 26 Oct 2018 14:00:02 EDT news459768436
