The latest graphene sensor news:
Archer Materials has announced a milestone in the development of its biochip, which is being created to detect various deadly communicable diseases.
The company achieved electronic transport in atom-thin graphene integrated with silicon electronics. Various voltage ranges were repeatedly recorded on the integrated devices when current-voltage traces were performed.
INBRAIN Neuroelectronics signs an agreement to develop neurotechnology patented by six public research institutions
INBRAIN Neuroelectronics has signed an agreement for the exploitation and development of three patents and a trade secret, mainly held by the Institute of Microelectronics of Barcelona (IMB-CNM) of the Spanish Council for Scientific Research (CSIC), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), the Institució Catalana de Recerca i Estudis Avançats (ICREA) and the Biomedical Research Centre Network CIBER BBN. The Universitat Autónoma de Barcelona (UAB) and the Institut de Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS) are also co-owners of the patents. This is a successful process of technology transfer in a public-private collaboration with multiple research institutions.
The company will carry out the development and manufacturing of these technologies within the Institut Català de Nanociència i Nanotecnologia (ICN2) and the Micro and Nanofabrication Clean Room of the Institute of Microelectronics of Barcelona (IMB-CNM) of the CSIC.
U.S-based graphene flakes producer Avadain has announced that it will upscale its environmentally friendly process to mass production as part of a two-year project funded by a $3.77 million grant from the U.S. Department of Commerce’s National Institute for Standards and Technology (NIST).
“We are excited to unleash the Graphene Revolution by making large, thin and nearly defect free graphene flakes available in industrial volumes and acceptable cost,” says Bradley Larschan, CEO of Avadain.
Graphenea has released a new product intended to make sensing with graphene easier: The Cartridge S2X, a package that interfaces the graphene microdevice and the electrical equipment used for its readout.
The cartridge has a small cleft onto which to place the GFET die, just below the electronics module with gentle pogo contacts to the graphene chip. The contacts are placed for seamless integration with Graphenea's S20, S21, S20P and S21P graphene chips that are especially designed for biosensing. The design makes use of 8 connections to the chip, including six source electrodes, one drain, and one gate. The pins are routed to a standard 8-pin BNC connector, for an easy and robust link to external measurement equipment.
Researchers from Boston College, Boston University, and Giner Labs have designed a small graphene-based multiplexed bio-sensor that detects opioid byproducts in wastewater.
The novel device uses graphene-based field effect transistors to detect four different synthetic and natural opioids at once, while shielding them from wastewater’s harsh elements. When a specific opioid metabolite attaches to a molecular probe on the graphene, it changes the electrical charge on the graphene. These signals are easily read electronically for each probe attached to the device.
