medical engineering (36) 썸네일형 리스트형 stress sensing epidermal sensor -Rogers Group developed a multifunctional skin-mounted microfluidic device that is able to measure stress in people in multiple ways. prior teams have developed skin-adhesive devices that that collect sweat samples. The tiny samples contain small amounts of cortisol, a hormone that can be used as a marker of stress levels. In this new effort, the researchers have improved on these devices by developing one th.. antigen detection on LFA by using glycan The new diagnostic tool uses glycans (sugars) to detect the virus, using a tool very similar to a home pregnancy test. "The rapid detection of the virus, for both healthcare and to enable society to return to normal is crucial. Our technology, developed through joint Ph.D. student work with our industry partners, makes use of glyco-nanomaterials to detect a specific portion of the coronavirus. T.. CRISPR-based diagnostic for COVID-19 have been working on a CRISPR-based diagnostic for COVID-19 that can produce results in 30 minutes to an hour, with similar accuracy as the standard PCR diagnostics now used. The new test, known as STOPCovid, is still in the research stage but, in principle, could be made cheaply enough that people could test themselves every day. https://youtu.be/ZGZYhX4-xH4 In the new version of STOPCovid repo.. Acoustic tweezers - 논문 읽고 리뷰하자 Acoustic tweezers are a powerful, versatile set of tools that use sound waves to manipulate bioparticles ranging from nanometer-sized extracellular vesicles to millimeter-sized multicellular organisms. Over the past several decades, the capabilities of acoustic tweezers have expanded from simplistic particle trapping to the precise rotation and translation of cells and organisms in three dimensi.. COVID-19 detection using wavelength shift when binding The device, described in a proof-of-concept study published this week in Biosensors and Bioelectronics, uses portable lab-on-a-chip technology to accurately measure the concentration of antibodies present in diluted blood plasma. The researchers avoided this trade-off between accuracy and accessibility by developing an alternative antibody testing platform that combines a powerful light-sensing .. serum에서 paper based sensor로 lithium 측정하기 Lithium carbonate is used for treating bipolar disorder, a mental health condition that causes extreme mood swings. But using this drug requires caution because the therapeutic concentration range of lithium ions in blood is narrow and close to the toxic range. existing examination methods require a large amount of blood, special operations, and large, expensive devices. The researchers succeede.. Raman activated droplet sorting The mining of useful enzymes and microbial cells that produce them has dated back nearly a century. However, such endeavors can be very slow and difficult due to the tiny size of microbes—1000 times smaller than a human cell. Moreover, most of the microbial cells cannot be readily cultured—for this reason, microbiologists call them "biological dark matter." "This is a flow-mode Raman-activated C.. pressure sensitive nano particel *** When nanocellulose is combined with various types of metal nanoparticles, materials are formed with many new and exciting properties. They may be antibacterial, change color under pressure, or convert light to heat. The research group, led by Daniel Aili, has used a biosynthetic nanocellulose produced by bacteria and originally developed for wound care. The scientists have subsequently decorated.. 이전 1 2 3 4 5 다음
