Graphene-Based Field-Effect Transistor for Ultrasensitive Immunosensing of SARS-CoV-2 Spike S1 Antigen

ACS Applied Bio Materials, Год журнала: 2022, Номер 5(7), С. 3563 - 3572

Опубликована: Июль 1, 2022

Coronavirus disease (COVID-19) is an infectious that has posed a global health challenge caused by the SARS-CoV-2 virus. Early management and diagnosis of are crucial for timely treatment, traceability, reduction viral spread. We have developed rapid method using Graphene-based Field-Effect Transistor (Gr-FET) ultrasensitive detection Spike S1 antigen (S1-Ag). The in-house antispike antibody (S1-Ab) was covalently immobilized on surface carboxy functionalized graphene channel carbodiimide chemistry. Ultraviolet-visible spectroscopy, Fourier-Transform Infrared Spectroscopy, X-ray Photoelectron Spectroscopy (XPS), Atomic Force Microscopy (AFM), Optical Microscopy, Raman Scanning Electron (SEM), Enzyme-Linked Immunosorbent Assays (ELISA), device stability studies were conducted to characterize bioconjugation fabrication process Gr-FET. In addition, electrical response evaluated monitoring change in resistance Ag-Ab interaction real time. For S1-Ag, our Gr-FET devices tested range 1 fM μM with limit 10 standard buffer. fabricated highly sensitive, specific, capable detecting low levels S1-Ag.

All-Carbon Solution-Gated Transistor with Low Operating Voltages for Highly Selective and Stable Dopamine Sensing

ACS Sensors, Год журнала: 2023, Номер 8(3), С. 1211 - 1219

Опубликована: Фев. 10, 2023

The diversity of carbon materials makes it possible to prepare all-carbon electronic devices requiring components with different properties and functions. In this work, we fabricate an solution-gated transistor (AC-SGT) based dopamine (DA) sensor Nafion coated nitrogen oxygen co-doped yarn (Nafion/NOCY) as the gate electrode graphene channel. in AC-SGT render usage a variety strategies improve its electrochemical sensing capability including modification modulation operating voltage. With low gate–source voltage 0.02 V well drain–source 0.05 V, manifests outstanding DA performances terms sensitivity, selectivity, limit detection (3 nM, S/N > 3), linear range nM 300 μM), long-term stability (over 30 days), preconditioning time (60 s). Furthermore, smartphone controlled portable system integrated is fabricated herein, which shows excellent vitro urine, proving potential transistors smart wearable biosensors.
