Paragraf launches 12-channel graphene FET platform and real-time reader
Paragraf has introduced a 12-channel graphene-based FET platform, featuring a real-time reader for enhanced performance in graphene electronics applications.
Paragraf, a leader in graphene electronics, has introduced two new products aimed at researchers and diagnostic developers: the PMF2002, a 12-channel graphene field-effect transistor (GFET) platform, and the Enterprise Reader, a system for direct electronic readout and real-time analysis.
The PMF2002 represents Paragraf's most advanced multiplexing GFET platform. It features a 12-channel, common-gate sensing architecture with separate source and drain connections for each channel. This design allows for simultaneous measurements across multiple channels from a single sample, enhancing efficiency and insight.
A GFET utilizes a graphene sheet as its channel, which is a single atom thick. This unique structure allows charged molecules binding to the graphene to alter its carrier concentration and conductance. By functionalizing the surface with a receptor layer, the GFET can selectively detect targets without the need for optical instrumentation.
The PMF2002's 12-channel layout is a significant advancement over the earlier PMF2000, which had three channels. The additional channels enable parallel assays from a single sample, allowing for multiple target detection, statistical replicates, and on-chip reference channels. This is particularly useful in diagnostics where sample material is limited.
The Enterprise Reader complements the PMF2002 by providing real-time electronic readouts and analysis. This integration allows researchers to observe sensor responses as they occur, facilitating quicker adjustments to functionalization chemistry and detection thresholds.
Both products are manufactured at Paragraf's dedicated graphene foundry in Huntingdon, Cambridgeshire. Paragraf's proprietary process grows graphene directly on standard semiconductor substrates, maintaining compatibility with established manufacturing processes and avoiding contamination issues associated with transfer methods.
Paragraf, a spin-out from the University of Cambridge, has secured over $150 million in private investment and operates across multiple international sites. Its product line includes the GHS series of graphene Hall-effect sensors and the PV01 GFET platform, which preceded the PMF2000.
