Nanotechnology delivers A selection of opportunities to contribute to biology. Right here I will present examples in which nanofabrication – the opportunity to make confined buildings with Proportions at will – is made use of to examine the biophysics of single molecules and cells. I will present some illustrations from our lab:

Back in 1991, Sumio Iijima from the NEC Company had documented the synthesis of carbon nanotubes. Band framework calculations proposed that these nanotubes could show metallic band conduction. This may be a big edge about the conducting polymers we experienced explored, which ended up, in truth, disordered semiconductors presenting just variable-selection hopping conductivity.
A rhythmically pulsing leaf-spring DNA-origami nanoengine that drives a passive follower Mathias Centola
This yielded a breakthrough. In only a few months, we ended up capable of evaluate transport as a result of a person one-walled carbon nanotube. Depending on low-temperature experiments by an excellent PhD student in my group, Sander Tans (now a valued colleague and professor at Delft College of Engineering having an Energetic investigate lab at AMOLF in Amsterdam), we showed that carbon nanotubes were being real quantum wires with incredibly lengthy (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic conduct.
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of an individual wire bridging two electrodes
‘In the beginning we checked out Organic systems using a Actual physical perspective and acted on the basis with the tools we knew. It took a several years right before we began Functioning additional on the massive biological problems. I then started to simply call it nanobiology, a time period that didn't exist at the time.
2011, initial in vitro measurements of transportation throughout one biomimetic nuclear pore advanced; progress of multiplexed magnetic tweezers for kilo-molecule experiments; and solved the mechanism of homology recognition in DNA homologous recombination
Imagine if, as opposed to using regular leading-down silicon electronics, transistors can be created from the bottom up employing single organic and natural molecules because the switching things? This idea, which grew to become the basis of currently’s area of molecular electronics, initially emerged inside the 1970s.
It absolutely was throughout this period that Dekker completed investigation on magnetic spin devices and on sounds in superconductors and semiconductors.
An built-in microfluidic platform for quantifying drug permeation across biomimetic vesicle membranes
2006, first demonstration of molecular sorting within a lab over a chip using biomotors; discovery of nanobubbles in sound-condition nanopores; and to start with estimate of electrokinetic Vitality conversion inside of a nanofluidic channel
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of only one wire bridging two electrodes
The biophysicist from Delft – who has long been One of the more cited experts while in the Netherlands For a long time – will take his duty to add to your clarification and popularisation of his perform in the ceesdekker.net border of physics and biology extremely very seriously and on a regular basis appears within the media; Otherwise to mention his perform, then about the connection involving science and his Christian faith.
