WebWe present a graphene-based biosensor selective to recombinant cyanovirin-N (rCV-N), an antiviral protein that has proven to be an effective microbicide to inhibit HIV replication. We modified the graphene monolayer devices with 1-pyrenebutanoic acid succinimidyl ester, which interacts with both graphene and the primary and secondary amines of antibodies. WebJan 14, 2024 · In this work, we developed a new multi-functional graphene FET with a PLL-functionalized channel (PGFET) biosensor integrated with a microfluidic structure, in short a PGFET biosensor, for ultrasensitive, specific, rapid detection of breast cancer miRNAs and SARS-CoV-2 RNAs, as shown in Figure 1.
WebStarting from advanced NEGF physical simulation of a 100 nm gate length Graphene FET, we attempt to use these results as a starting point to evaluate this technology for microwave circuit benchmarking. Using an improved compact model carefully adjusted on NEGF simulation data, in both DC and AC regime, we use this model to design a mmW ... WebGraphene-FET (G-FET) realizes such high-sensitive elec. detection of the targets, owing to graphene's high carrier mobility. In the present study, G-FET was functionalized using sialoglycans and employed for the selective detection of lectins from Sambucus sieboldiana and Maackia amurensis as alternatives of the human and avian influenza viruses.
