The latest graphene sensor news:
Sussex team granted £1 million funding to develop graphene-based applications like camouflage technology, smart tires and more
A University of Sussex research team, led by Professor Alan Dalton, has received new funding of £1 million from private company Advanced Material Development, to pursue their research into graphene and other nanomaterials.
The team will conduct research into various avenues, including camouflage technology to stop soldiers from being spotted by thermal imaging cameras or night vision goggles. The team will also develop their research into anti-counterfeiting graphene inks which can be printed onto clothes and medicine containers; incorporated into smart tires which monitor for problems; used on banknotes; included on metal-free radio-frequency identification tags (RFID) tags for supermarkets to track products; and wearable technology, including monitors for babies’ heartbeats or diabetic patients’ glucose levels.
Researchers at the University of Illinois at Urbana-Champaign have found that crumpling graphene makes it more than ten thousand times more sensitive to DNA by creating electrical "hot spots". This discovery could assist in addressing a known issue of graphene-based biosensors - the face that they require a lot of DNA in order to function properly.
"This sensor can detect ultra-low concentrations of molecules that are markers of disease, which is important for early diagnosis," said study leader Rashid Bashir, a professor of bioengineering and the dean of the Grainger College of Engineering at Illinois. "It's very sensitive, it's low-cost, it's easy to use, and it's using graphene in a new way."
As researchers and companies all over the world set out to battle the Coronavirus pandemic, many are revisiting graphene as a material with potential for helping to win this fight. The reasons for such potential could be found in graphene's known antibacterial/antiviral properties, its beneficial traits for medical sensors and devices and more.
Graphene has been shown in the past as extremely useful for creating various sensors. Earlier this month, a team led by Boston College researchers used a sheet of graphene to track the electronic signals inherent in biological structures, in order to develop a platform to selectively identify deadly strains of bacteria. In October 2019, Rice University team under chemist James Tour transformed their laser-induced graphene (LIG) into self-sterilizing filters that grab pathogens out of the air and kill them with small pulses of electricity. Commercially sold graphene-based sensors exist, like the graphene oxide (GO) sensor developed by the ICN2 Nanobioelectronics and Biosensors group that was added in 2016 to the list products offered by Biolin Scientific, a prestigious instrumentation company devoted to the production of analytical devices. The Q-Sense GO sensor enables interaction studies of GO with various analytes (measured substances) of interest and may open the door to various applications with interest for diagnostics, safety/security and environmental monitoring.
A team led by Boston College researchers has used a sheet of graphene to track the electronic signals inherent in biological structures, in order to develop a platform to selectively identify deadly strains of bacteria. This effort could lead to more accurate targeting of infections with appropriate antibiotics, according to the team.
The prototype demonstrates the first selective, rapid, and inexpensive electrical detection of the pathogenic bacterial species Staphylococcus aureus and antibiotic resistant Acinetobacter baumannii on a single platform, said Boston College Professor of Physics Kenneth Burch, a lead co-author of the paper.
Following a Global Business innovation Programme initiated in 2019, and a collaborative visit to the US, the UK established a new Graphene Innovation Group (UK-GIG) that puts together 15 specialists from UK companies that together share many years of experience in graphene and expertise across the entire value chain.
Scott Storey, a Business Innovation Advisor at Inventya and the lead coordinator at the UK-GIG, explains more about the group - "We can take an everyday industrial challenge, apply our combined graphene knowledge, engineer and manufacture an effective solution, and take that solution to national and international markets. UK-GIG is now an established cohort of 15 UK-based graphene companies, ranging from early stage through to established businesses. The UK-GIG companies are fully aware of the huge potential for graphene technology to improve materials or be used in novel ways across multiple sectors. They are seeking collaboration opportunities where they can combine their expertise to do what they do best - solve problems, design graphene applications, and help commercialize an increasingly exciting field. They aim to make the UK the best place on earth to be grafting in graphene!"
We have reached out to some of the GIG members, to find out how has graphene effected their business and products, and the effects of graphene on their materials or devices.
