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..
Detection of COVID-19 in Exhaled Breath Now, researchers reporting in ACS Nano have developed a prototype device that non-invasively detected COVID-19 in the exhaled breath of infected patients. colleagues wanted to develop a nanomaterial-based sensor that could detect COVID-19 in exhaled breath, similar to a breathalyzer test for alcohol intoxication. Previous studies have shown that viruses and the cells they infect emit volatile or..
syringe injecting high concentrated drug Absract Needle에 lubricant를 넣어서 high concentration이어도 잘 나오게 해줬다는 논문이다. reference Vishnu Jayaprakash et al. Enhancing the Injectability of High Concentration Drug Formulations Using Core Annular Flows, Advanced Healthcare Materials (2020). DOI: 10.1002/adhm.202001022
ML로 blood quality test 하기 Each year, nearly 120 million units of donated blood flow from donor veins into storage bags at collection centers around the world. The fluid is packed, processed and reserved for later use. But once outside the body, stored red blood cells (RBCs) undergo continuous deterioration. By day 42 in most countries, the products are no longer usable. For years, labs have used expert microscopic examin..
oxygen therapy could affect lung microbiome One of the hallmarks of severe COVID-19 is shortness of breath and significantly reduced levels of oxygen in the blood, called hypoxemia. Upon hospitalization, these patients are administered oxygen in an attempt to bring their levels back up to normal. However, a new study hints that this universal therapy may have unintended consequences via an unexpected source—the microbiome. "It had been as..
pericytes들을 연결해주는 cell structure we have identified a communication structure between cells that is required to coordinate blood supply in the living retina, "We already knew that activated retinal areas receive more blood than non-activated ones," she said, "but until now no one understood how this essential blood delivery was finely regulated." Wrapped around the capillaries are pericytes, cells that have the ability to contr..
how to overcome coffee ring effect the coffee ring effect. This effect has hindered the industrial deployment of functional inks with graphene, 2-D materials, and nanoparticles because it makes printed electronic devices behave irregularly. Now, after studying this process for years, a team of researchers have created a new family of inks that overcomes this problem, enabling the fabrication of new electronics such as sensors, li..
improving Nano-particle delivery University of Toronto Engineering researchers have discovered a dose threshold that greatly increases the delivery of cancer-fighting drugs into a tumor. "It's a very simple solution, adjusting the dosage, but the results are very powerful," Nanotechnology carriers are used to deliver drugs to cancer sites, which in turn can help a patient's response to treatment and reduce adverse side effects,..
