UrduEn el calor abrasador del verano, cualquier persona que pase tiempo afuera podría beneficiarse de un tejido refrigerante. Pero ahora, los investigadores han innovado con un revestimiento de microescala a base de tiza que enfría el aire debajo del tejido tratado hasta 13 grados Celsius. Presentarán sus resultados en la ACS Fall 2024.

Improving access to heart-failure screening with saliva
Heart failure is especially fatal for people without access to medical facilities. A research team aims to bring heart failure screening from the lab to the home with a biosensor that uses a drop of saliva to screen for biomarkers of the disease. They will present their results at ACS Fall 2024.
Novel Micro-OLED Technology with Over 20K ppi Resolution
Using the strategy of “surface patterning and patterned growth,” scientists have developed an ultrahigh-resolution organic semiconductor device fabrication technology.
Hitting this stretchy, electronic material makes it tougher
Dropping wearable electronics, or hitting them really hard, usually breaks the devices. Now, researchers report on a flexible and electrically conductive material with “adaptive durability,” getting stronger when it is hit. They will present their results at ACS Spring 2024.
Self-powered microbial fuel cell biosensor for monitoring organic freshwater pollution
Ritsumeikan University researchers designed a low-cost biosensor for assessing water quality at the input of lakes and rivers
Call for Papers and Participants: The 16th Eurasia Conference on Chemical Science 2023 (EuAsC2S–16) – Frontiers in Chemical Sciences for Sustainability
The Department of Chemistry, Faculty of Science, Chulalongkorn University, together with the Chemical Society of Thailand will co-organize “the 16th Eurasia Conference on Chemical Science 2023 (EuAsC2S–16)” under the theme “Frontiers in Chemical Sciences for Sustainability”, from December 13-15, 2023 at the Berkeley Hotel Pratunam, Bangkok.
Sweat it out: Novel wearable biosensor for monitoring sweat electrolytes for use in healthcare and sports
The remarkable level of miniaturization possible in modern electronics has paved the way for realizing healthcare devices previously confined to the realm of science fiction.
Wearable, Printable, Shapeable Sensors Detect Pathogens and Toxins in the Environment
Researchers at Tufts University have created a biopolymer sensor that can be printed on or embedded in wide range of materials, including gloves, masks, and everyday clothing. The sensor lights up when exposed to specific pathogens, toxins, proteins, or chemicals.
Innovative Self-Powered Ingestible Sensor Opens New Avenues for Gut Research
Engineers developed a battery-free, pill-shaped ingestible biosensing system that gives scientists the ability to monitor gut metabolites in real time, which wasn’t possible before. The work could lead to a new understanding of intestinal metabolite composition, which significantly impacts human health.
FAU Lands $1.2 Million NSF Grant to Transform Prosthetic Hand Control
Current prosthetic hands have five individually actuated digits, yet only one grasp function can be controlled at a time, which makes sophisticated tasks largely impossible.
New Low-cost Device Rapidly, Accurately Detects Hepatitis C Infection
The entire virus detection process is executed inside a uniquely designed, portable, inexpensive, disposable, and self-driven microfluidic chip. The fully automated sample-in–answer-out molecular diagnostic set-up rapidly detects Hepatitis C virus in about 45 minutes and uses relatively inexpensive and reusable equipment costing about $50 for sample processing and disease detection. The disposable microfluidic chip also offers shorter times for a reliable diagnosis and costs about $2.
Researchers recycle CDs into flexible biosensors
New research from Binghamton University, State University of New York offers a second life for CDs: Turn them into flexible biosensors that are inexpensive and easy to manufacture.
‘Smart necklace’ biosensor may track health status through sweat
Researchers have successfully tested a device that may one day use the chemical biomarkers in sweat to detect changes in a person’s health.
Fast, efficient COVID-19 biosensor under development
IUPUI researchers are developing a “biosensing platform” for COVID-19 that’s fast, efficient, accurate and highly sensitive, which could help scientists stay on top of shifting virus variants.
Wash-and-wear sensors
University of Utah chemical engineering assistant professor Huanan Zhang has developed a process that turns clothing fabric into biosensors which measure a muscle’s electrical activity as it is worn. This could become a much better solution in measuring muscle activity for physical rehabilitation or for other medical applications.
Making patient care easier: Self-powered diaper sensors that monitor urine sugar levels
Thanks to science and modern medicine, we know a lot more now about the early signs of certain diseases and which biomarkers to check.
Thin, stretchable biosensors could make surgery safer
A research team from Los Alamos National Laboratory and Purdue University have developed bio-inks for biosensors that could help localize critical regions in tissues and organs during surgical operations.
The Electrochemical Society Awards 2021 ECS Colin Garfield Fink Fellowship to Ali Othman
Ali Othman, PhD, Research Associate in Clarkson University’s Department of Chemical & Biomolecular Science, received The Electrochemical Society’s prestigious 2021 ECS Colin Garfield Fink Fellowship. The fellowship provides financial assistance for Othman’s research in the months of June through August. His work focuses nanomaterials and the interface chemistry of materials and their bio(sensing) and environmental applications.
Biosensors Require Robust Antifouling Protection
Some promising biosensors and medical devices work well within pristine laboratory environments but may stop working once exposed to real-world conditions. A thick layer of foulants will quickly cover biosensors, and there is no good way to revive them once they quit working. Essentially, a biosensor is only as good as its antifouling properties. In APL Materials, researchers review a variety of approaches developed to combat fouling.
Coping with Chaos
For our series, The ECS Community Adapts and Advances, Alice Suroviec describes pandemic-related challenges—and benefits—of being a mother, professor, scientist, researcher, administrator, homeschooler, and crisis manager. Alice is Professor of Bioanalytical Chemistry and Dean of the College of Medical and Natural Sciences at Berry College, Georgia, U.
