‘Indeed, that may be about proper. I try to find a Bodily understanding of biological devices inside of a bottom-up way. I feel you could distinguish three traces of investigate in my group at this time. The initial problems chromosome composition: How can you have a metre-long DNA polymer folded and organised in this type of microscopic mobile? Now we have created visualisation tactics that allow for us to study how, as an example, SMC proteins loop DNA (movie on Youtube) so that you can Develop up chromosomes.
Our group research bacterial cell division and is aiming to represent a ‘base up biology’ in artificial cells that may autonomously divide. Our principal fascination lies in mobile division, chromatin composition, and spatial Management.
, Groningen researchers present the outcomes of their attempts to generate labs additional sustainable and supply guidelines for other labs.
Our work was quickly followed up by Other folks, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 printed their conclusions on transistors constructed from single- and multi-walled carbon nanotubes in Utilized Physics Letters.
2012, discovery that nucleoid occlusion underlies the precision of bacterial mobile division; and initial at any time research of your dynamics DNA supercoils and the discovery of supercoil hopping
Experimental period diagram of negatively supercoiled DNA measured by magnetic tweezers and fluorescence,
What distinguishes biology from chemistry is the fact that these factors collectively make up a dwelling process. The trick of stated lifetime, I believe, lies from the interactions, the interplay of All those molecules. The big concern concerning the origin of daily life is still unanswered. How did we ever evolve from very simple molecules in to the exceptionally complicated units we see nowadays? We do not know. I want to work on These types of big, open inquiries.’
Nanopores depict a chic and adaptable Resource to evaluate solitary molecules. We analysis novel detection modes with sound-state nanopores along with different approaches to evaluate proteins with nanopores. Jobs encompass the next:
2003, shown the primary biosensors created from a carbon nanotube; resolved the composition and system of DNA fix proteins; and discovery of a fresh method for fabricating solid-point out nanopores for DNA translocation
Really neat, but that wasn’t truly the place my interest lay. I desired to ceesdekker.net pioneer And that i experienced the feeling that was no more possible, because the most exciting essential insights had already been uncovered. But my discipline experienced made numerous interesting new applications to evaluate person molecules. I decided that I planned to utilize this to biology, to have a look at it from a physical perspective.’
Tests pseudotopological and nontopological versions for SMC-driven DNA loop extrusion versus roadblock-traversal experiments
Numerous new phenomena were found out, and he and his investigation team recognized a leading situation On this industry of investigation. Dekker and his study team found new physics of nanotubes together with explored the feasibility of molecular electronics. In 1998, they had been the main to create a transistor dependant on an individual nanotube molecule.
2005, discovery of your mechanism of DNA uncoiling by topoisomerase enzymes; discovery of very long-variety conformational improvements in Mre11/DNA restore complexes; and initially force measurements on the DNA molecule inside of a nanopore
Stable-condition nanopores have demonstrated being a shockingly multipurpose probe for one-molecule Assessment of DNA. I'll explain a number of our latest findings – particularly DNA knots – in addition to our attempts to broaden the capabilities of good-point out nanopores even even further, from the route of solitary-protein detection, graphene nanopores, plasmonic nanopores, and DNA origami nanopores.
