Since winning the 2007 Foresight Institute Feynman Prize in Nanotechnology, Theory category, Professor David Leigh FRS FRSE FRSC MAE, and since 2012 at the University of Manchester, has continued to achieve major milestones on the road to complex systems of molecular machinery. Contributions we have recently cited here: First direct measurement of force generated by… Continue reading Molecular robot builds four types of molecules
Removing the necessity of providing several different chemical fuels in a series of distinct steps, a novel chemically-fueled molecular motor autonomously produces movement as long as the fuel supply lasts.
Scaffolded DNA origami is combined with hinges of single- or double-stranded DNA to built simple machines parts that have been combined to program simple to complex motions.
Combinations of different types of DNA nanorobots, implementing different logic gates, work together to tag a specific type of cell in a living cockroach depending on the presence or absence of two protein signals.
Among the smallest molecular robots reported so far, a walker based on phenylarsonous acid with two organic thiol ligands as feet walks through a one-nanometer-diameter protein nanopore channel by taking 0.6 nanometer steps, by thiol exchange, from one cysteine residue to the next.
Nanotech promises more commonplace access to advanced technology as material and fabrication costs fall and traditional barriers to innovation are removed. Examples are already being seen globally: more access to laptops and cell phones in developing countries, desktop 3D printers, a surge in establishment of shared-use research facilities, etc. A couple recent cases getting attention… Continue reading Recent cases of 'accessible' high-tech: Open source chips & Origami robots
With biotech fundamental to several paths to advanced nanotechnology, a way to do biotech experiments in the cloud offers small groups the chance to quickly test their ideas.
One research group working with rotaxanes and another group working with carbon nanotubes have provided two very different solutions to the problem of producing motion via artificial muscles at different scales from the nano to the macro.
A prototype humanoid robot being developed for the US military mimics a wide range of human movements while retaining its balance.
The Singularity University Executive Program recently took on the challenges of advanced nanotech: Nanotechnology: How should we evaluate the environmental impact of human-made machines that are too small to see? What limits should be placed on self-replicating nanodevices? What defenses should we institute against malevolent uses of such technology? These questions were asked by Marc… Continue reading Singularity University takes on advanced nanotech questions
