Effect of humidity on graphene sensors demistified

Graphene produced with chemical vapor deposition (CVD) will form the cornerstone of future graphene-based chemical, biological, and other types of sensors. Graphene, however, is extremely sensitive to air, in particular to humidity. To avoid unwanted background coming from humidity and to calibrate future sensors, it is highly important to investigate...

Graphene aids optical study of dye molecules

Dyes have long been used as colorants, stains, and markers. Their potential use as optical materials has been widely investigated, especially in recent years in the context of dye-sensitized solar cells, where dyes play the role of sunlight absorber. In order to study and understand the optical properties of dye...

Hybrid graphene – quantum dot infrared photodetectors for food safety

Infrared (IR) thermometry has proven to be an ideal tool for food control inspectors and regulators. A means of measuring food temperature from afar and under versatile conditions, IR thermometers are used to detect food that has started to go bad, improving food quality and increasing productivity. Now, Graphenea and the...

Graphene oxide and rGO microparticles not toxic to mouse lung cells

Recent research showed that graphene (reduced graphene oxide, rGO) and graphene oxide (GO) particles larger than 1 micron in size are not cytotoxic or genotoxic to mouse lung cells. The study, performed using Graphenea graphene and involving the company's scientists, tested GO and rGO toxicity epithelial FE1 cells in vitro....
