Fresh Meat: New Biosensor Accurately and Efficiently Determines Meat Freshness

sarah JonasResearch Results

Despite the technological advances keeping meat fresh for as long as possible, certain aging processes are unavoidable. Adenosine triphosphate is a molecule produced by breathing and responsible for providing energy to cells. When an animal stops breathing, ATP synthesis also stops, and the existing molecules decompose into acid, diminishing first flavor and then safety. Hypoxanthine and xanthine are intermediate steps in this transition. Assessing their prevalence in meat indicates its freshness. In AIP Advances, researchers developed a biosensor using graphene electrodes modified by zinc oxide nanoparticles to measure HXA. The team demonstrated the sensor’s efficacy on pork meat.

Point-of-Care Biosensor Rapidly Detects Oral Cancer

sarah JonasResearch Results

Since oral cancer occurs in one of the most accessible sites in the body, it can be easily treated if detected promptly. In Journal of Vacuum Science & Technology B, researchers report a breakthrough hand-held biosensor that enables quick and accurate detection of oral cancer. The group’s biosensor consists of a sensor strip, similar to a glucose strip, and a circuit board (a hand-held terminal like a glucometer) for detection.

Tracking Muscle Activity with Clothes on Your Back

sarah JonasResearch Results

In APL Materials, researchers have developed a bioelectrical sensor that is convenient and low-cost. The sensor measures electromyography signals that are generated in muscles when they contract and are useful for studying muscle fatigue and recovery, and they have the potential to inform diagnosis and treatment of neuromuscular diseases. The biosensor, made of silver paste with a layer of gold nanoparticles on top, is directly integrated onto a piece of clothing. The result was a detector that was both conductive and nonirritating to the skin.

Appropriate Technologies: The COVID-19-Era Heroes Yet to Come to “Center Stage”

sarah JonasFeature

The COVID-19 outbreaks in Thailand have seen an ever-increasing number of infections as new clusters are emerging. The faculty members of Sasin School of Management — Prof. Dr. Kua Wongboonsin, Asst. Prof. Dr. Piyachart Phiromswad, Assoc. Prof. Dr. Pattanaporn Chatjuthamard, Asst. Prof. Dr. Pattarake Sarajoti, and Asst. Prof. Dr. Sabin Srivannaboon, with financial support from the National Research Council of Thailand (NRCT), jointly present ways to reduce the spread of COVID-19 sustainably in a study to identify technologies that can instantly and appropriately help professionals who find social distancing difficult.

New dopamine sensors could help unlock the mysteries of brain chemistry

sarah JonasResearch Results

In 2018, Tian Lab at UC Davis Health developed dLight1, a single fluorescent protein-based biosensor. This sensor allows high resolution, real-time imaging of the spatial and temporal release of dopamine in live animals. Now, the team expanded the color spectrum of dLight1 to YdLight1 and RdLight1. The increased light penetration and imaging depth of these variants provide enhanced dopamine signal quality allowing researchers to optically dissect dopamine’s release and model its effects on neural circuits.
