Making use of single-molecule optical and AFM imaging and force-spectroscopy approaches, we search for to unravel the mechanistic areas of the framework and dynamics of chromosomes. Our analysis interests consist of:

Human Rad51 filaments on double- and one-stranded DNA: correlating normal and irregular kinds with recombination function.

Throughout the identical time, the team of Paul McEuen, who was then dependent on the University of California, Berkeley, confirmed equivalent effects on ropes of bundled nanotubes. With regards to the wrapping angle, nanotubes can are available metallic or semiconducting variants, a prediction that we and Charles Lieber’s team at Harvard College independently confirmed working with scanning tunnelling spectroscopy experiments.

Sad to say, For many years soon after Iijima’s report, the production of clear nanotubes was cumbersome. In 1996, nevertheless, the team of Richard Smalley at Rice College managed to supply one-walled carbon nanotubes at large generate. Shortly immediately after, I contacted Smalley, and we decided to be part of forces to evaluate the transport by way of a one carbon nanotube.

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

Experimental stage diagram of negatively supercoiled DNA calculated by magnetic tweezers and fluorescence,

All parameters ended up a similar for every panel During this movie, apart from the initial placement on the 6hb rod ceesdekker (revealed in blue) over the nanopore. Simulations that terminated early because of translocation in the rod through the pore are marked by a grey background.

2011, very first in vitro measurements of transport across a single biomimetic nuclear pore complex; development of multiplexed magnetic tweezers for kilo-molecule experiments; and fixed the mechanism of homology recognition in DNA homologous recombination

2003, demonstrated the main biosensors built outside of a carbon nanotube; solved the construction and mechanism of DNA repair proteins; and discovery of a completely new system for fabricating stable-condition nanopores for DNA translocation

Extremely interesting, but that wasn’t really in which my desire lay. I wanted to pioneer and I experienced the sensation which was no longer attainable, as the most fascinating elementary insights experienced previously been uncovered. But my industry had created quite a few exciting new resources to measure particular person molecules. I made a decision that I desired to use this to biology, to take a look at it from the Actual physical point of view.’

An built-in microfluidic System for quantifying drug permeation across biomimetic vesicle membranes

‘That issues the artificial mobile, as Portion of the Dutch BaSyC initiative. Craig Venter appeared leading-down in All those times and recognized about 5 hundred genes which are minimally expected for a operating cell. We want to seem bottom-up: how can we move from a few molecules to a whole Organic procedure?

Developments in nanotechnology from the nineteen nineties designed setting up Digital equipment from one molecules a risk. Cees Dekker recounts how his team created a room-temperature transistor based on a single carbon nanotube.

Instance (two) of bending configurations in 3D simulations of DNA rods on nanopores. A portion of the membrane is revealed in grey, the rim with the pore is highlighted in crimson, in addition to a 3D rendering with the motion on the DNA rod is displayed.
