Using one-molecule optical and AFM imaging and drive-spectroscopy tactics, we find to unravel the mechanistic facets of the structure and dynamics of chromosomes. Our investigate passions contain:

It absolutely was only while in the nineteen nineties even though, when nanotechnology experienced Superior to some amount exactly where one molecules might be manipulated, that the 1st experimental devices started to look.

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

Since 2000, Dekker has shifted the principle aim of his perform toward biophysics where he scientific studies the Houses of single biomolecules and cells using the equipment of nanotechnology. This alteration of field was driven by his fascination to the amazing operating of Organic molecular buildings, as well as through the very long-time period perspective that a lot of exciting discoveries is often envisioned in this area.[5] Existing traces of investigation in his biophysics team are from the parts of:[six]

2012, discovery that nucleoid occlusion underlies the precision of bacterial cell division; and initially ever analyze on the dynamics DNA supercoils and the discovery of supercoil hopping

Microbiology has only been around for the century, due to the fact we began to analyze micro-organisms more critically. I believed nanobiology was an acceptable expression, for the reason that all molecular Organic appropriate interactions happen on the nanoscale: a protein is a couple of nanometres in dimension, DNA is 2 nm thick.’

Many related developments adopted, exactly where our team set up different transistor variants for instance single-electron transistors at room temperature and intramolecular nanotube junctions that acted as rectifying diodes, and cees dekker coupled various transistors into smaller proof-of-principle Digital circuits.

Researching DNA loop extrusion by SMC proteins for chromosome architecture with single-molecule assays.

In 1993, being a young and eager affiliate professor at Delft College of Technological innovation, I had at first centered the exploration efforts of my team on measuring the electrical conductance of only one conducting-polymer molecule. Within two yrs, we had established a tool through which one wire of a phthalocyaninepolysiloxane polymer was linked amongst two intently spaced steel nanoelectrodes.

‘The fantastically subtle way in which features in mother nature operate in no way ceases to amaze me. If we resolve the puzzle of how life arrived into currently being, I hope that my amazement for the complexity of development may have increased and with it my awe for that greatness in the Creator.’

2001, discovery of solitary-electron transistors at area temperature determined by nanotubes; realization of initially logic circuits with carbon nanotube equipment; and discovery of your molecular composition of DNA maintenance enzymes with AFM

Developments in nanotechnology in the 1990s produced creating electronic gadgets from single molecules a likelihood. Cees Dekker recounts how his staff made a home-temperature transistor dependant on only one carbon nanotube.

2004, discovery of new physics in translocation of DNA as a result of nanopores; 1st experimental study of ions conduction in nanofluidic channels; to start with electrochemistry with specific single-wall carbon nanotubes; STM detection and Charge of phonons in carbon nanotubes; initial electrical docking of microtubules on kinesin-coated nanostructures; to start with biophysics characterization on the mechanical properties of double-stranded RNA; and initially single-molecule analyze of DNA translocation by a restriction-modification enzyme.
