Employing single-molecule optical and AFM imaging and drive-spectroscopy procedures, we search for to unravel the mechanistic facets of the construction and dynamics of chromosomes. Our study pursuits include:

1996, to start with mesoscopic cost density waves products; and very first electrical measurements on only one steel nanocluster concerning nanoelectrodes

Dynamics of initiation, termination and reinitiation of DNA translocation because of the motor protein EcoR124I

Sculpting nano-electrodes with a transmission electron beam for electrical and geometrical characterization of nanoparticles.

This yielded a breakthrough. Within just only a few months, we ended up capable of evaluate transport as a result of a person one-walled carbon nanotube. Depending on low-temperature experiments by an excellent PhD university student in my group, Sander Tans (now a valued colleague and professor at Delft College of Engineering having an active exploration lab at AMOLF in Amsterdam), we showed that carbon nanotubes were being real quantum wires with incredibly lengthy (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic conduct.

Microbiology has only been around for any century, due to the fact we began to analyze micro-organisms more seriously. I thought nanobiology was an suitable phrase, since all molecular biological pertinent interactions happen with the nanoscale: a protein is a number of nanometres in dimensions, DNA is two nm thick.’

All parameters have been the identical for every panel in this video clip, apart from the First placement with the 6hb rod (revealed in blue) on the nanopore. Simulations that terminated early because of translocation on the rod from cees dekker the pore are marked by a gray qualifications.

2011, first in vitro measurements of transportation throughout one biomimetic nuclear pore advanced; progress of multiplexed magnetic tweezers for kilo-molecule experiments; and solved the mechanism of homology recognition in DNA homologous recombination

The rotors harness Electricity from a nanoscale h2o and ion stream that is certainly generated by a static chemical or electrochemical potential gradient during the nanopore, that happen to be set up through a salt gradient or used voltage, respectively. These artificial nanoengines self-organize and run autonomously in physiological situations, suggesting ways to setting up Power-transducing motors at nanoscale interfaces.

There was one issue even though — we did not observe any measurable electrical conduction from The only polymer molecules. We concluded that at The only-molecule degree, conducting polymers were being actually not this kind of excellent conductors, which was relatively disappointing. We Consequently broadened our perspective to test to search out extra promising molecules.

An integrated microfluidic System for quantifying drug permeation throughout biomimetic vesicle membranes

2001, discovery of one-electron transistors at home temperature based on nanotubes; realization of initial logic circuits with carbon nanotube gadgets; and discovery in the molecular construction of DNA mend enzymes with AFM

Developments in nanotechnology from the nineteen nineties designed setting up Digital equipment from one molecules a possibility. Cees Dekker recounts how his team produced a space-temperature transistor according to just one carbon nanotube.

Supercoiling-dependent DNA binding: quantitative modeling and programs to bulk and one-molecule experiments
