- "This Platform Grant (PG) will apply our internationally-leading expertise in structured illumination and hybrid inorganic/organic semiconductor optoelectronic devices to create new opportunities in the rapidly developing field of light-controlled manufacturing. Structured illumination fields can in principle be obtained from both inorganic (GaN) and organic LEDs, implemented on a macroscale via relay optics, or demagnified to a microscale. Novel manufacturing with photopolymerisable materials can firstly involve use of structured illumination as a novel means to control motorised stages. This technique can be combined with pattern-programmable UV excitation for mask-free photolithographic patterning, continuous photo-curing over larger fields, localised photochemical deposition, or other forms of photo-labile assembly. Process variants can also be envisaged in which arbitrarily positioned fluorescent objects or markers are 'hunted', and then subject to beam excitation for photocuring or targeted photoexcitation. This method could be used, for example, to immobilise individual colloidal quantum dots for use as emitters in quantum technology applications. Multifunctional devices with sensing ability, such as organic lasers for explosives detection, represent another excellent example of automated devices operating under remote conditions. Further examples of the envisaged uses of this technology include:
 LED microdisplay asset tags for management of high-value objects (artworks, nuclear fuel containers).
 Passive asset tags containing unique micro-patterns of fluorescent objects (eg. colloidal quantum dots, organic macromolecules) for higher-volume, anti-counterfeiting applications.
 Customisable continuous-flow micro-reactors for fine chemical manufacturing.
 Energy harvesting micro-modules to power other autonomous microsystems, where we will focus on organic PV and ambient-radiation (RF) approaches."

- "The smallest scale on which it is possible to design functional devices, including electronics, is the molecule scale (about 100,000 times smaller than the width of a human hair). This is the ultimate limit for miniaturisation and motivates research to manipulate and study the properties of individual molecules for applications in, e.g., information technologies and sensors. It is also the scale at which quantum phenomena dominate properties, so single-molecule structures offer a domain for investigations ranging from fundamental tests of quantum theory to developing components for future quantum technologies.
To realise such experiments and technologies, it is necessary to incorporate individual molecules into electrical circuits. This is challenging because the typical size of a useful functional molecule is much smaller than the smallest wires that it is possible to fabricate, even with the most sophisticated lithography systems available today. Most researchers use one of two approaches.
The first uses an electrical current or mechanical strain to make a tiny gap, a few nanometres across, in a thin wire, and then deposit the molecules of interest randomly, hoping that one and only one bridges the gap. This method relies on chance, and so it very rarely yields a working device: typically, only a very small proportion of devices fabricated show behaviour consistent with a single molecule in the gap and, because the shape of the gap and the orientation of the molecule are uncontrolled, it is rare for even such working devices to exhibit reproducible properties.
The second method uses a scanning tunnelling microscope to locate and investigate molecules that are deposited on a conducting surface. This process is much more reliable and reproducible than the break junction method but it involves bulky experimental apparatus and it tightly limits the experimental geometry, ruling out the development of more complicated experiments or practical devices.
These limitations in the existing methods have hamstrung the development of molecule-scale devices and technologies. Further progress in this field now requires the development of controlled and reliable methods that can be scaled to high volume production. This project will provide this methodology and demonstrate a range of prototype molecular devices.
Our approach is based on DNA nanotechnology, which has, over the last decade, proved itself to be a powerful tool for controlled self-assembly of structures at the molecular scale. We will use these methods to direct the assembly of packages about 100 nanometres across. Constructed mainly from DNA with a precisely programmed structure, these packages will position gold nanoparticle contacts and the target molecular components, whose electrical transport properties we would like to exploit, with sub-nanometre accuracy.
Our method produces trillions of packages at a time in a test-tube and ensures that each one has exactly the correct molecules incorporated in the correct positions and orientations between contacts. These gold nanoparticle contacts are large enough that we can connect them to laboratory equipment using standard nanolithography techniques. The technology has the potential for future development to connect multiple molecules in three-dimensional device architectures, and for the assembly of large-scale integrated molecular circuits.
We propose to create several families of devices, designed to develop and prove this radically new molecular device fabrication methodology. These devices will give us an unprecedented experimental tool for probing electrical and magnetic properties of molecules, but they will also establish the potential for the industrial deployment of our technology. Central to the project are close interactions with industrial partners and knowledge transfer activities designed to accelerate commercial applications."
