Taking materials into the third dimension

To create more efficient catalysts, scientists would like to start with porous materials with controlled atomic-scale structures as random defects can hamper performance. Now a team has created a one-pot method that produces the structures.

New class of materials could revolutionize biomedical, alternative energy industries

Polyhedral boranes, or clusters of boron atoms bound to hydrogen atoms, are transforming the biomedical industry. These humanmade materials have become the basis for the creation of cancer therapies, enhanced drug delivery and new contrast agents needed for radioimaging and diagnosis. Now, a researcher has discovered an entirely new class of materials based on boranes that might have widespread potential applications, including improved diagnostic tools for cancer and other diseases as well as low-cost solar energy cells.

New sensors can detect single protein molecules

For the first time, engineers have designed sensors that can detect single protein molecules as they are secreted by cells. These sensors, which consist of modified carbon nanotubes, could help scientists with any application that requires detecting very small amounts of protein, such as tracking viral infection, monitoring cell manufacture of useful proteins, or revealing food contamination.

Synthetic nanoparticles achieve the complexity of protein molecules

Chemists have demonstrated that synthetic nanoparticles can achieve the same level of structural complexity, hierarchy and accuracy as biomolecules. The study, published in Science, also reveals the atomic-level mechanisms behind nanoparticle self-assembly, providing an important window into how nanoparticles form. The findings could help guide the construction of nanoparticles, including those that can be used in the creation of computer chips, materials, drugs and drug delivery devices.

Toward a ‘smart’ patch that automatically delivers insulin when needed

Treatment for certain diabetes cases involves constant monitoring of blood-glucose levels and daily insulin shots. But scientists are now developing a painless “smart” patch that monitors blood glucose and releases insulin when levels climb too high.

A ‘strand’ of DNA as never before

(Nanowerk News) In a carefully designed polymer, researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences have imprinted a sequence of a single strand of DNA. The resulting negative remained chemically active and was capable of binding the appropriate nucleobases forming a genetic code. The polymer matrix – the first of its type in history – thus functioned exactly like a sequence of real DNA Source:…
