The starting point is a glass plate coated with cell-repellent material. The desired circuit pattern is scratched into this coating and then coated with a cell-friendly adhesive. Unable to gain purchase on most of the plate, the cells are forced to grow in the scratched areas.
The scratched paths are thin enough to force the neurons to grow along them in one direction only, forming straight wire-like connections around the circuit.
Using this method the researchers built a device that acts like an AND logic gate, producing an output only when it receives two inputs.
"In a paper in Nature Mr. Tay and colleagues describe their thin-film polymer that can have images "written" to it in minutes and can be wiped as quickly to take and display another image.
The material has been shown to stay stable throughout hundreds of write and erase cycles.
The ability to quickly refresh images in holographs could mean that surgeons use them as a guide during operations or as a better way for pharmaceutical researchers to study molecular interactions for new drugs during simulations.
"The Patent and Trademark Office is starting a pilot project that will not only post patent applications on the Web and invite comments but also use a community rating system designed to push the most respected comments to the top of the file, for serious consideration by the agency's examiners. A first for the federal government, the system resembles the one used by Wikipedia, the popular user-created online encyclopedia.
