Nanopore Integrated Nanogaps for DNA Detection

László Forró, Arnaud Magrez, Aleksandra Radenovic, Axel Fanget, Floriano Traversi, Sergey Khlybov

A high-throughput fabrication of sub-10 nm nanogap electrodes combined with solid-state nanopores is described. These devices should allow concomitant tunneling and ionic current detection of translocating DNA molecules. We report the optimal fabrication p ...

Detecting the translocation of DNA through a nanopore using graphene nanoribbons

Aleksandra Radenovic, Andras Kis, Ke Liu, Daria Krasnozhon, Camille Alice Raillon, Floriano Traversi, Mohamed Malik Benameur, Sergey Khlybov

Solid-state nanopores can act as single-molecule sensors and could potentially be used to rapidly sequence DNA molecules. However, nanopores are typically fabricated in insulating membranes that are as thick as 15 bases, which makes it difficult for the de ...

ssDNA Binding Reveals the Atomic Structure of Graphene

Aleksandra Radenovic, Andras Kis, Paolo Annibale, Floriano Traversi

We used AFM to investigate the interaction of polyelectrolytes such as ssDNA and dsDNA molecules with graphene as a substrate. Graphene is an appropriate substrate due to its planarity, relatively large surfaces that are detectable via an optical microscop ...

Vertical arrays of nanofluidic channels fabricated without nanolithography

Klaus Kern, Floriano Traversi, Kannan Balasubramanian

Vertical arrays of sealed nanofluidic channels, in which both cross-sectional dimensions are controllable down to 10 nm, were fabricated by selective side etching of a SiGe heterostructure comprised of layers of alternating Ge fractions. Capillary filling ...
