You frequently get involved in conversations about science and faith. You have got also prepared a number of textbooks on the subject. Don’t you believe at some time we will know anything and that God’s purpose will probably be around?

Back in 1991, Sumio Iijima of the NEC Corporation experienced claimed the synthesis of carbon nanotubes. Band composition calculations suggested that these nanotubes could exhibit metallic band conduction. This could be a substantial benefit above the conducting polymers we had explored, which had been, actually, disordered semiconductors providing simply variable-variety hopping conductivity.

Sculpting nano-electrodes using a transmission electron beam for electrical and geometrical characterization of nanoparticles.

This yielded a breakthrough. In only a few months, we ended up in a position to evaluate transport by an individual one-walled carbon nanotube. According to small-temperature experiments by an excellent PhD university student in my group, Sander Tans (now a valued colleague and professor at Delft College of Technologies by having an active investigation lab at AMOLF in Amsterdam), we confirmed that carbon nanotubes have been legitimate quantum wires with extremely very long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic conduct.

Microbiology has only existed for just a century, given that we started to examine micro-organisms additional very seriously. I assumed nanobiology was an correct time period, because all molecular biological relevant interactions take place in the nanoscale: a protein is a couple of nanometres in dimension, DNA is 2 nm thick.’

We form microorganisms into varieties that deviate from their all-natural phenotype. Exclusively, I'll clearly show our capability to condition Dwell E. coli micro organism into novel designs for example rectangles, squares, triangles and circles.

Atomic drive microscopy shows that vaccinia topoisomerase IB generates filaments on DNA inside of a cooperative trend

The rotors harness Strength from the nanoscale h2o and ion flow that is produced by a static chemical or electrochemical likely gradient from the nanopore, that are proven via a salt gradient or used voltage, respectively. These synthetic nanoengines self-Arrange ceesdekker.net and run autonomously in physiological situations, suggesting ways to constructing Power-transducing motors at nanoscale interfaces.

Dekker began his exploration on single carbon nanotubes in 1993 when he put in place a completely new line of study to review electrical transport by one organic and natural molecules involving nanoelectrodes. In 1996 a breakthrough was recognized with carbon nanotubes. This was achieved within a collaboration Together with the group of Nobel laureate Richard Smalley. STM and nanolithography strategies had been used to show that these nanotubes are quantum wires at the single-molecule degree, with fantastic Actual physical properties.

Since 2000 he moved to one-molecule biophysics and nanobiology, with investigation from scientific studies of DNA loop extrusion and supercoiling to DNA translocation by means of nanopores. Much more recently his exploration has focused on learning chromatin structure and mobile division with microorganisms on chip, while he is usually aiming to in the end Establish synthetic cells from The underside up.

2006, initially demonstration of molecular sorting inside a lab on the chip applying biomotors; discovery of nanobubbles in strong-condition nanopores; and initially estimate of electrokinetic energy conversion within a nanofluidic channel

One example is, we think about the nucleopore sophisticated, a gateway amongst the mobile nucleus and the cytoplasm. This is a very complicated method and for that reason tricky to study in a cell, so we use biomimetics. We reconstruct holes and then insert person factors in the nucleopore advanced to study transport through it at the single-molecule degree.’

It was an incredibly attention-grabbing time, all through which I been given loads of support from Delft College of Engineering, exactly where I had been a professor at some time, and I started out numerous collaborations with molecular biologists. That aided me discover a lot.’
