New technology will use graphene biosensors to rapidly test for malaria

Researchers at the International Iberian Nanotechnology Laboratory (INL) and Research Institute for Life and Health Sciences (ICVS) at the University of Minho in Portugal will develop a graphene-based device that allows the early diagnosis of malaria, in a fast and reliable way, and at an accessible cost.

Over the course of a year, both institutions will work to utilize the technology of graphene-based sensors, developed at INL.

Ultraviolet light on a graphene surface could eliminate toxic mercury in UV light devices

A research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology (NTNU) has succeeded in creating ultraviolet light on a graphene surface. This could be beneficial for eliminating the toxic mercury element common in ultraviolet light devices that are used to kill bacteria and viruses.

“We’ve created a new electronic component that has the potential to become a commercial product. It’s non-toxic and could turn out to be cheaper, and more stable and durable than today’s fluorescent lamps. If we succeed in making the diodes efficient and much cheaper, it’s easy to imagine this equipment becoming commonplace in people’s homes. That would increase the market potential considerably,” says PhD candidate Ida Marie Høiaas.

Researchers develop a graphene-based biosensor that detects bacterial presence

Researchers from Myongji University, Sungkyunkwan University, Gachon University and Korea Institute of Science and Technology in South Korea, along with U.S-based Villanova University, have developed a new device concept for bacterial sensing by Raman spectroscopy and voltage-gated monolayer graphene.

Synthesis of the monolayer graphene was done by chemical vapor deposition (CVD) on a Cu foil, which was eventually channelized onto a SiO2 /Si substrate. Modification of Raman spectra is examined in the study in order to develop ultra-sensitive biosensing techniques for the detection, identification, differentiation and classification of bacteria associated with infectious diseases.

Grafoid launches a new company to focus on graphene 3D Printing

Canadian graphene developer Grafoid announced that it launched a new company, called Grafprint3D, to develop and produce 3D printing materials based on Grafoid's MesoGraf graphene - although Grafprint3D's current materials are actually graphene inks for screen printing and inkjet printing and not 3D printed ones.

Grafoid says that initially the new company will focus on wearable device fabrication with biocompatible polymers, biomaterial substrates for cell therapy engineering research, and rapid product prototyping with printable advanced nanomaterials.

Researchers develop washable, wearable graphene capacitors that can be woven directly into clothes

Researchers at the University of Cambridge and Jiangnan University in China have developed graphene-enhanced wearable electronic components incorporated directly into fabrics. The devices could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications.

The researchers have shown how graphene and other related materials can be directly incorporated into fabrics to produce charge storage elements such as capacitors, paving the way to textile-based power supplies which are washable, flexible and comfortable to wear.
