‘Of course, that is about appropriate. I search for a Bodily idea of biological programs in a base-up way. I do think you may distinguish a few strains of analysis in my team in the meanwhile. The first considerations chromosome framework: how do you obtain a metre-prolonged DNA polymer folded and organised in this kind of microscopic mobile? We've designed visualisation procedures that allow us to study how, one example is, SMC proteins loop DNA (online video on Youtube) in order to Construct up chromosomes.
You often become involved in conversations about science and faith. You have also published numerous guides on the subject. Don’t you think that in some unspecified time in the future We are going to know everything Which God’s role might be more than?
, Groningen researchers present the results of their efforts to create labs a lot more sustainable and provide methods for other labs.
Considering that 2000, Dekker has shifted the main target of his get the job done towards biophysics the place he experiments the properties of solitary biomolecules and cells using the instruments of nanotechnology. This change of area was driven by his fascination for that remarkable functioning of biological molecular constructions, together with via the long-expression standpoint that many fascinating discoveries might be predicted With this industry.[five] Current lines of study in his biophysics group are inside the regions of:[6]
2012, discovery that nucleoid occlusion underlies the precision of bacterial cell division; and initially ever review in the dynamics DNA supercoils and the invention of supercoil hopping
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of an individual wire bridging two electrodes
What distinguishes biology from chemistry is these factors with each other make up a dwelling program. The trick of stated everyday living, I believe, lies during the interactions, the interplay of All those molecules. The big concern about the origin of lifetime is still unanswered. How did we at any time evolve from simple molecules to the exceptionally sophisticated devices we see these days? We don't know. I need to operate on these kinds of massive, open up concerns.’
Studying DNA loop extrusion by SMC proteins for chromosome architecture with solitary-molecule assays.
‘Indeed, I have an understanding of folks were being stunned at some time. At the end of the nineties, Once i was in my forties, I had been Professor of Molecular Electronics and I have to confess that it experienced become a bit bored, I didn’t master Significantly anymore. The sphere went a lot more into the applying facet, how you may combine nanotubes into Digital circuits.
Right now, we also recognized that it should be achievable to work with an individual semiconducting carbon nanotube to generate a transistor — and we set out to make it. We stretched individual semiconducting nanotubes throughout metallic electrodes and made use of the fundamental silicon substrate being a gate electrode, developing The fundamental three-terminal structure of the discipline-influence transistor (Fig.
Considering the fact that 2000 he moved to solitary-molecule biophysics and nanobiology, with study from experiments of DNA loop extrusion and supercoiling to cees dekker DNA translocation by way of nanopores. Much more recently his exploration has focused on finding out chromatin construction and mobile division with germs on chip, though he can be attempting to finally Create artificial cells from the bottom up.
Nature Physics many thanks the anonymous reviewers for his or her contribution on the peer assessment of the operate.

Solid-state nanopores have proven to become a remarkably flexible probe for single-molecule Evaluation of DNA. I will describe some of our recent conclusions – precisely DNA knots – as well as our endeavours to extend the abilities of stable-condition nanopores even even more, inside the path of single-protein detection, graphene nanopores, plasmonic nanopores, and DNA origami nanopores.
