The graphene-based Field Effect Transistors (GFETs), due to their multi-parameter characteristics, are growing rapidly as an important detection component for the apt of disease biomarkers, such DNA, in clinical diagnostics and biomedical research laboratories. In this paper, non-equilibrium Green function (NEGF) is used create a compact model GFET ballistic regime building block DNA sensors. p...

Smart sensors based on graphene field effect transistor and biologically receptors are regarded as a promising nanomaterial that could be the basis for future generations of selective real-time monitoring of target analytes and smaller electronics. So the purpose of this paper is to provide details a real-time and selective explosive sensor based on GFETs and PDA-based lipid membranes coupled w...

One of the most significant issues that occurs when applying chemical-vapor deposited (CVD) graphene (Gr) to various high-performance device applications is the result of polymeric residues. Polymeric residues remain on the Gr surface during Gr polymer support transfer to an arbitrary substrate, and these residues degrade CVD Gr electrical properties. In this paper, we propose that a thin layer...

Graphene has unique electrical and mechanical properties which can pave the way for new types of devices microwave applications. However, emerging technologies often have problems with yield still considerable variation in device parameters cause great challenges circuit design. In this paper, we present design development an integrated graphene FET amplifier addressing challenge. A representat...

This technical report describes the development of an aptamer for sensing azole antifungal drugs during therapeutic drug monitoring. Modified synthetic evolution of ligands through exponential enrichment (SELEX) was used to discover a DNA aptamer recognizing azole class antifungal drugs. This aptamer undergoes a secondary structural change upon binding to its target molecule, as shown through f...

Transistors operating at high frequencies are the basic building blocks of millimeter-wave communication and sensor systems. The charge-carrier mobility saturation velocity in graphene can open way for ultra-fast field-effect transistors with a performance even better than what be achieved III-V-based semiconductors. However, progress high-speed has been hampered by fabrication issues, influenc...

The most affected disease in recent years is Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) that notable as COVID-19. It has been started a one place and arisen pandemic throughout the world. A serious health problem developed lungs due to effect of this coronavirus. Sometimes it may result death consequence extensive alveolar damage progressive respiratory failure. Hence, early d...

Ultraviolet (UV) photodetectors often suffer from the lack of spectral selectivity due to strong interference visible light. In this study, exceptional electrical properties graphene and unique optical carbon nitride thin films (CNTFs) are used design visible-blind UV photodetectors. First, polycrystalline CNTFs with different thicknesses (12–94 nm) produced by thermal vapor condensation. Compa...

Graphene’s distinctive band structure gives rise to exciting new transport properties and promising applications for carbon-based electronics.1–3 When measuring the conductance or current noise in a nanotube or a sheet of graphene, the properties of the contacts can matter as much as the electronic structure of the nanotube or graphene itself. In semiconducting nanotubes or graphene nanoribbons...
