Loeff, L. (author), Kerssemakers, J.W.J. (author), Joo, C. (author), Dekker, C. (author)Single-molecule techniques allow the visualization of the molecular dynamics of nucleic acids and proteins with high spatiotemporal resolution. Valuable kinetic information of biomolecules can be obtained when the discrete states within single-molecule time trajectories are determined. Here, we present a fast, automated, and bias-free step...journal article 2021

Resolving Chemical Modifications to a Single Amino Acid within a Peptide Using a Biological NanoporeRestrepo Perez, L. (author), Huang, Gang (author), Bohländer, Peggy R. (author), Worp, N.M. (author), Eelkema, R. (author), Maglia, Giovanni (author), Joo, C. (author), Dekker, C. (author)While DNA sequencing is now amply available, fast, and inexpensive, protein sequencing remains a tremendous challenge. Nanopores may allow for developing a protein sequencer with single-molecule capabilities. As identification of 20 different amino acids currently presents an unsurmountable challenge, fingerprinting schemes are pursued, in...journal article 2019

Shi, X. (author), Verschueren, D.V. (author), Dekker, C. (author)Plasmon resonance biosensors provide ultimate sensitivity at the single-molecule level. This sensitivity is, however, associated with a nanometer-sized confined hotspot, and molecular transport toward the sensor relies on inefficient diffusion. Here, we combine a plasmonic nanoantenna with a solid-state nanopore and demonstrate that single...journal article 2018

Heerema, S.J. (author), Vicarelli, L. (author), Pud, S. (author), Schouten, R.N. (author), Zandbergen, H.W. (author), Dekker, C. (author)Many theoretical studies predict that DNA sequencing should be feasible by monitoring the transverse current through a graphene nanoribbon while a DNA molecule translocates through a nanopore in that ribbon. Such a readout would benefit from the special transport properties of graphene, provide ultimate spatial resolution because of the single...journal article 2018
