Complex 3D-nano patterns with indentation lithography and piezo technology

A collaboration between the Whitesides Group at Harvard University and CSM Instruments has culminated in an important advance in lithography of different materials at the nanoscale. The motivation for this development was the ability to produce unique lithographical patterns of different shapes and sizes for use in research applications (e.g. lab-on-a-chip) where conventional techniques such as electron-beam lithography (EBL) and photolithography cannot be used.

Researchers construct RNA nanoparticles to safely deliver long-lasting therapy to cells

Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, in which therapeutic agents can be delivered inside the body via nanoparticles. But the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress. Now, researchers detail successful methods of producing large RNA nanoparticles and testing their safety in the delivery of therapeutics to targeted cells.

Nanoscale vaults encapsulate nanodisks for drug delivery

The development of new methods that use engineered nanomaterials to transport drugs and release them directly into cells holds great potential in this area. And while several such drug-delivery systems have won approval for clinical use, they have been hampered by size limitations and ineffectiveness in accurately targeting tissues. Now, researchers at UCLA have developed a new and potentially far more effective means of targeted drug delivery using nanotechnology.

Successful workshop "Energy and Innovation"

The enormous changes with respect to how we handle and consume energy and the impact on the environment are of great concern not only to us as scientists, but also to all of us as responsible citizen. Therefore, the PhD students of the International Doctorate Program NanoBioTechnology had the wish to establish a discussion with experts from relevant fields to get a deep insight into the technical, economic and social preconditions necessary for the creation of a truly sustainable energy supply system.

New DNA nanoforms take shape (w/video)

Miniature architectural forms - some no larger than viruses - have been constructed through a revolutionary technique known as DNA origami. Now, Hao Yan, Yan Liu and their colleagues at ASU's Biodesign Institute have expanded the capability of this method to construct arbitrary, two- and three-dimensional shapes, mimicking those commonly found in nature.

Limit to top-down nanotechnology mass-production?

A leading nanotechnology scientist has raised questions over a billion dollar industry by boldly claiming that there is a limit to how small nanotechnology materials can be mass produced. He says that you cannot mass produce structures with a diameter of three nanometres or less using a top-down approach.
