The cancer drug paclitaxel just got more effective. For the first time, researchers from the University of North Carolina at Chapel Hill have packaged it in containers derived from a patient’s own immune system, protecting the drug from being destroyed by the body’s own defenses and bringing the entire payload to the tumor.
New research directed by Dr Neil Kad, of the School of Biosciences, has led to the use of the nanoprobe to study how individual proteins interact with DNA. Invisible to the human eye, this tiny triangular probe can be captured using laser tweezers and then moved around inside a microscope chamber.
A team of researchers from the University of Illinois have created a novel material composite obtained from quantum dots.
Researchers from the University of California, Davis (UC Davis) and the University of Washington have shown the possibility of using DNA-based electromechanical switches for nanoscale computing.
A novel technique that uses optical fibre to track the motion of single, nanoscale viruses has been developed. It is hoped that this technique will allow researchers to understand the mechanisms by which viruses multiply and accumulate.
Physical chemists have devised a rolling DNA-based motor that’s 1,000 times faster than any other synthetic DNA motor, giving it potential for real-world applications, such as disease diagnostics. Nature Nanotechnology is publishing the finding.
Researchers have determined that the bright blue colour of tarantulas are the result of multilayer nanostructures present in their hair. The researchers hope to mimic the hairs properties to create new dyes, and to improve the performance of computer and TV screens.
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.
