A key technological breakthrough led by the University of Edinburgh suggests that a futuristic world where people can move objects about ‘remotely’ with laser pointers could be closer than we think. Chemists working on the nanoscale (80,000 times smaller than a hair’s breadth) have managed to move a tiny droplet of liquid across a surface – and even up a slope – by transporting it along a layer of light-sensitive molecules.
Scientists at Edinburgh, Groningen and Bologna are the first to manipulate tiny nanoscale machines (two millionths of a millimetre high) so that they can move an object that is visible to the naked eye. The team has shifted microlitre drops of diiodomethane not just across a flat surface, but also up a one millimetre, 12 degree slope against the force of gravity. It may be the tiniest of movements, but, in the emerging discipline of nanotechnology, it represents a giant technological leap forward.
Although many scientists are working with so-called ‘molecular machines’ – a process which involves making the parts of molecules move in a controlled fashion – the Edinburgh-led team is the first to make these machines interact with ‘real world’ objects. Until now, molecular machines have operated in isolation within the laboratory, but this latest piece of research brings them into contact with the everyday world around us.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
