Ting Xu, a polymer researcher from the Materials Sciences Division of Lawrence Berkeley National Laboratory (Berkeley Lab), has developed a novel set of nanocarriers that are produced from the self-assembly of polymers and amphiphilic peptides. Amphiphiles are a type of chemical compounds that have both lipophilic and hydrophilic characteristics. Micelles are spherical amphiphile aggregates. These nanocarriers have a structure of coiled-coil 3-helix micelles and hence, referred to as 3HM.
A new high resolution method, that uses atomic force microscopy, has been developed that allows the exact shape of a receptor and it's affinity towards a particular ligand to be measured simultaneously. This has never been achieved before and will prove extremely useful in understanding the complex mechanisms behind cell communication.
New research has shown quantum dots can be used to map neural networks in the brain by allowing neural signals to be visualised in real time. This breakthrough will allow further insight into neural communication in both normal and abnormal brains.
A nanoparticle drug delivery system has been developed by the researchers from the California NanoSystems Institute at UCLA for the antibiotic moxifloxacin. This system improves the efficacy of the drug and also minimizes the side effects.
A team of engineers from the University of Wisconsin-Madison have developed miniature lenses with a wide range of vision inspired by the multi-faceted eyes of insects. For the first time ever, flexible, Fresnel zone plate microlenses featuring a large field of view have been developed based on this novel approach.
Researchers at The University of Texas at Austin have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or drug targeting.
MIT engineers have designed magnetic protein nanoparticles that can be used to track cells or to monitor interactions within cells. The particles, described today in Nature Communications, are an enhanced version of a naturally occurring, weakly magnetic protein called ferritin.
At the University of Cologne, biophysicists in the lab of Professor Berenike Maier were now able to show how differential mechanical forces can lead to cell sorting in biofilms, thereby determining their architecture.
An overview of the range of useful applications of halloysite clay tubes has been published. The naturally occuring, biocompatible, nanoscale tubes can be used for sustained drug delivery and alongside enzymes as biocatalytic nanoreactors.
Gold is one of the world’s best-known precious metals. For thousands of years, it’s been crafted into jewelry, medals and coins. When mixed with alloys, it can take on a white or rose-colored cast, but its natural hue is a deep, rich, unmistakable yellow.
