Nanotechnology presents a range of options to lead to biology. Below I'll existing illustrations where by nanofabrication – a chance to make confined structures with Proportions at will – is utilized to examine the biophysics of single molecules and cells. I will present some examples from our lab:
Our team reports bacterial cell division and is also aiming to constitute a ‘base up biology’ in synthetic cells that may autonomously divide. Our main desire lies in cell division, chromatin construction, and spatial control.
The subsequent posts are merged in Scholar. Their mixed citations are counted only for the main article.
A rhythmically pulsing leaf-spring DNA-origami nanoengine that drives a passive follower Mathias Centola
This yielded a breakthrough. Within just only a few months, we were being capable to evaluate transport as a result of someone one-walled carbon nanotube. Based upon reduced-temperature experiments by a superb PhD student in my team, 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 ended up genuine quantum wires with quite long (micrometres) electronic 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
‘To start with we checked out biological programs with a physical look at and acted on The premise from the equipment we realized. It took a number of years ahead of we begun Operating a lot more on the large Organic challenges. I then started to get in touch with it nanobiology, a expression that didn't exist at some time.
2011, to start with in vitro measurements of transportation throughout an individual biomimetic nuclear pore sophisticated; advancement of multiplexed magnetic tweezers for kilo-molecule experiments; and settled the mechanism of homology recognition in DNA homologous recombination

1). The existing–voltage curves showed sizeable modulations with gate voltage, even at area temperature, which was consistent with band bending in the ~0.six eV bandgap semiconducting nanotube. These info also confirmed that the conductance may very well be modulated by six orders of magnitude by shifting the gate voltage. The results of this get the job done — a space-temperature transistor constructed from a single carbon nanotube molecule — have been posted in Nature in May well 1998.
Testing pseudotopological and nontopological types for SMC-pushed DNA loop extrusion against roadblock-traversal experiments
‘That issues the artificial mobile, as A part of the Dutch BaSyC initiative. Craig Venter appeared top-down in People times and identified about five hundred genes which have been minimally needed for your functioning mobile. We wish to look bottom-up: how can we shift from a number of molecules to an entire Organic technique?
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of just ceesdekker one wire bridging two electrodes
Finally, I will briefly sketch some of our Suggestions to investigate the constructing of synthetic cells, precisely our first actions to establish synthetic cell division.
