The new water-resistant gas sensor can be worn under the nose to detect nitrogen dioxide in the breath, the concentration of which may indicate potential pulmonary diseases.

Researchers develop sensors based on graphene foam for better prosthetics and robotics

Researchers from Integrated Graphene and the University of the West of Scotland (UWS) have reported a project to develop graphene-enhanced pressure sensors that provide enhanced capabilities to robots, helping improve their motor skills and dexterity. The project was supported by the Scottish Research Partnership in Engineering (SRPe) and the National Manufacturing Institute for Scotland (NMIS) Industry Doctorate Program in Advanced Manufacturing.

Professor Des Gibson, Director of the Institute of Thin Films, Sensors and Imaging at UWS and project principal investigator, said: “Over recent years the advancements in the robotics industry have been remarkable, however, due to a lack of sensory capabilities, robotic systems often fail to execute certain tasks easily. For robots to reach their full potential, accurate pressure sensors, capable of providing greater tactile ability, are required. Our collaboration with Integrated Graphene Ltd, has led to the development of advanced pressure sensor technology, which could help transform robotic systems.”

Paragraf announces Innovate UK grant to develop graphene-based diagnostic tool

Paragraf has announced its plan to develop a new generation of graphene-based, in-vitro diagnostic products that will give results within a few minutes.

The Company is starting a two-year program to develop a proof-of-concept combined PCT (procalcitonin) and CRP (C-reactive protein) test, on a single panel. This collaboration utilizes a GBP £550,000 (around USD$658,000) Biomedical Catalyst grant award from Innovate UK, the UK’s innovation agency.

Researchers develop graphene-based same-time, same-position biomolecule isolation and sensing

Researchers from the University of Massachusetts Amherst have demonstrated an advance in using graphene for electrokinetic biosample processing and analysis, that could allow lab-on-a-chip devices to become smaller and achieve results faster.

The team developed devices that incorporate microelectrodes made of monolayer graphene. They found that the electrolysis stability over time for graphene microelectrodes is >103× improved compared to typical microfabricated inert-metal microelectrodes. Through transverse isoelectric focusing between graphene microelectrodes, within minutes, specific proteins can be separated and concentrated to scales of ∼100 μm.

Soft graphene-based probe monitors brain and gut chemistry

Scientists from Michigan State University and Stanford University have invented the “NeuroString” — a graphene-based implantable probe that enables researchers to study the chemistry of brain and gut health.

“The mainstream way people are trying to understand the brain is to read and record electric signals,” said Jinxing Li, the paper’s first author and an assistant professor in MSU’s College of Engineering. “But chemical signals play just as significant a role in brain communication, and they are also directly related to diseases. My lab at MSU focuses on developing cutting-edge neuroprobes and microrobotics.”
