Chitosan-graphene biosensors and methods for their use
TL;DR: In this article, a method for detecting mutations in polynucleotide sequences through the use of a glassy carbon electrode (GCE) coated with a chitosan-graphene nanosheet material (also referred to herein as a “CMG electrode”) is presented.
Journal ArticleDOI
Engineered Recombinant Proteins for Aqueous Ultrasonic Exfoliation and Dispersion of Biofunctionalized 2D Materials
TL;DR: The production of stable, low-defect, and biofunctionalized 2D flakes of graphene by using bifunctional chimeric polyproteins as dispersants is shown, demonstrating the versatility of this approach.

3D electron diffraction of mono- and few-layer MoS2.
TL;DR: In this article, 3D electron diffraction (3D ED) was used to distinguish unambiguously between 1-, 2-, 3- 4- and 5-layer MoS2 crystals.

Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.

Two-dimensional gas of massless Dirac fermions in graphene
Kostya S. Novoselov,A. K. Geim,Sergey V. Morozov,Da Jiang,Mikhail I. Katsnelson,Irina V. Grigorieva,S. V. Dubonos,A. A. Firsov +7 more
TL;DR: This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.

TL;DR: This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.
