Facile and Ultraclean Graphene-on-Glass Nanopores by Controlled Electrochemical Etching
Xiaoyan Zhang, Pauline M. G. van Deursen, Wangyang Fu +1
A wide range of approaches have been explored to meet the challenges of graphene nanostructure fabrication, all requiring complex and high-end nanofabrication platform and sufferin…
Ultrasensitive Field-Effect Biosensors Enabled by the Unique Electronic Properties of Graphene
Xiaoyan Zhang, Qiushi Jing, Shen Ao +4
This review provides a critical overview of current developments on nanoelectronic biochemical sensors based on graphene. Composed of a single layer of conjugated carbon atoms, gra…
Electrical probing of COVID-19 spike protein receptor binding domain via a graphene field-effect transistor
Xiaoyan Zhang, Qige Qi, Qiushi Jing +9
Here, in an effort towards facile and fast screening/diagnosis of novel coronavirus disease 2019 (COVID-19), we combined the unprecedently sensitive graphene field-effect transisto…
Large-scale BN tunnel barriers for graphene spintronics
Wangyang Fu, Péter Makk, Romain Maurand +2
We have fabricated graphene spin-valve devices utilizing scalable materials made from chemical vapor deposition (CVD). Both the spin-transporting graphene and the tunnel barrier ma…
Rendering graphene supports hydrophilic with non-covalent aromatic functionalization for transmission electron microscopy
Radosav S. Pantelic, Wangyang Fu, Christian Schoenenberger +1
Amorphous carbon films have been routinely used to enhance the preparation of frozen-hydrated transmission electron microscopy (TEM) samples, either in retaining protein concentrat…
Electrolyte gate dependent high-frequency measurement of graphene field-effect transistor for sensing applications
W. Fu, M. El Abbassi, T. Hasler +8
We performed radiofrequency (RF) reflectometry measurements at 2.4 GHz on electrolyte-gated graphene field-effect transistors (GFETs) utilizing a tunable stub-matching circuit for…
