Nanotechnology gives A selection of alternatives to add to biology. Listed here I will current illustrations where by nanofabrication – the ability to make confined structures with dimensions at will – is employed to look at the biophysics of solitary molecules and cells. I'll current some illustrations from our lab:
Reconstitution of ultrawide DNA origami pores in liposomes for transmembrane transportation of macromolecules
Round the identical time, the group of Paul McEuen, who was then dependent on the College of California, Berkeley, confirmed comparable success on ropes of bundled nanotubes. Dependant upon the wrapping angle, nanotubes can are available in metallic or semiconducting variants, a prediction that we and Charles Lieber’s team at Harvard University independently verified making use of scanning tunnelling spectroscopy experiments.
A rhythmically pulsing leaf-spring DNA-origami nanoengine that drives a passive follower Mathias Centola
2010, made a brand new way (‘wedging transfer’) to control nanostructures; to start with report of DNA translocation by means of graphene nanopores; and recognized hybrid nanopores by directed insertion of α-hemolysin into stable-point out nanopores
While in the decades next these discoveries, my investigate passions shifted to biophysics and nanobiology, and I became much less involved in the event of nanotube electronics. The main target of many researchers in the sphere also shifted to graphene (where by, funnily plenty of, the 1st graphene ribbons have been described as ‘nanotubes that are Slash open up along their duration’) immediately after the discovery of the two-dimensional material in 2004.
Duration Charge of specific carbon nanotubes by nanostructuring Together with the scanning tunneling microscope
2011, first in vitro measurements of transportation throughout one biomimetic nuclear pore intricate; growth of multiplexed magnetic tweezers for kilo-molecule experiments; and settled the mechanism of homology recognition in DNA homologous recombination

Dekker begun his exploration on solitary carbon nanotubes in 1993 when he setup a completely new line of investigation to study electrical transportation as a result of solitary natural and organic molecules in between nanoelectrodes. In 1996 a breakthrough was recognized with carbon nanotubes. This was realized within a collaboration With all the team of Nobel laureate Richard Smalley. STM and nanolithography techniques were accustomed to display that these nanotubes are quantum wires at The one-molecule degree, with outstanding Bodily properties.
[fourteen] In 2005 Dekker grew to become linked to Netherlands-vast conversations about Intelligent Layout, a motion that he has considering that Evidently distanced himself from. Dekker advocates that science and religion are certainly not in opposition but may be harmonized.
1999, first measurement on the wavefunction of single molecular cees dekker orbitals of carbon nanotubes; and discovery of kink heterojunctions of carbon nanotubes which gave decisive evidence for a new Luttinger description of interacting electrons in nanotubes
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of a single wire bridging two electrodes
Instance (two) of bending configurations in 3D simulations of DNA rods on nanopores. A part of the membrane is revealed in grey, the rim on the pore is highlighted in pink, as well as a 3D rendering of your motion with the DNA rod is shown.
