Scientists develop proteins that self-assemble into supramolecular complexes

Thu, 07/19/2018 - 17:44
Scientists have designed new proteins that can self-assemble into the complex structures underlying biological organisms, laying the groundwork for leading-edge applications in biotechnology. The researchers created and developed the proteins with a specific function and their method reveals a possibility that certain protein functions can be created on demand. It is expected to contribute to the development of nanobiomaterials, which could be used as a drug delivery system or an artificial vaccine.

A safe and effective way to whiten teeth

Wed, 07/18/2018 - 18:47
In the age of Instagram and Snapchat, everyone wants to have perfect pearly whites. To get a brighter smile, consumers can opt for over the counter teeth-whitening treatments or a trip to the dentist to have their teeth bleached professionally. But both types of treatments can harm teeth. Researchers have now developed a new, less destructive method.

Splitting water: Nanoscale imaging yields key insights

Wed, 07/18/2018 - 17:25
In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel -- just as plants do -- researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. Now scientists have pioneered a technique that uses nanoscale imaging to understand how local, nanoscale properties can affect a material's macroscopic performance.

Transmission of specific colors of light over long distances

Tue, 07/17/2018 - 19:24
Researchers have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. They explored a new way to select and send light of a specific color using long silicon wires that are several hundred nanometers in diameter and their work enabled a new type of nanoscale ''light switch'' that can turn on and off the transmission of one color of light over very long distances.

Single-celled architects inspire new nanotechnology

Mon, 07/16/2018 - 23:16
Scientists have designed a range of nanostructures resembling marine diatoms -- tiny unicellular creatures. To achieve this, they borrow techniques used by naturally-occurring diatoms to deposit layers of silica -- the primary constituent in glass -- in order to grow their intricate shells. Using a technique known as DNA origami, the group designed nanoscale platforms of various shapes to which particles of silica, drawn by electrical charge, could stick.

Scientists create nano-size packets of genetic code aimed at brain cancer 'seed' cells

Thu, 07/12/2018 - 18:05
In a 'proof of concept' study, scientists say they have successfully delivered nano-size packets of genetic code called microRNAs to treat human brain tumors implanted in mice. The contents of the super-small containers were designed to target cancer stem cells, a kind of cellular 'seed' that produces countless progeny and is a relentless barrier to ridding the brain of malignant cells.

Brain function partly replicated by nanomaterials

Thu, 07/12/2018 - 18:05
Researchers have created extremely dense, random SWNT/POM network molecular neuromorphic devices, generating spontaneous spikes similar to nerve impulses of neurons. They conducted simulation calculations of the random molecular network model complexed with POM molecules, which are able to store electric charges, replicating spikes generated from the random molecular network. They also demonstrated that this molecular model would very likely become a component of reservoir computing devices. Reservoir computing is anticipated as next-generation artificial intelligence.
