Collaboration among Case Western Reserve University, the University of Fribourg and the Army Research Laboratory uses light to trigger repair Your 6-year-old found a nail in the garage and drew pictures across the side of your new car. Gnash your teeth now, but researchers at Case Western Reserve University, U.S., say the fix-up may be cheap and easy to do yourself in the not-too-distant future. Together with partners in the USA and Switzerland, they have developed a polymer-based material...

New insights from the nano world The mechanism for binding oxygen to metalloporphyrins is a vital process for oxygen-breathing organisms. Understanding how small gas molecules are chemically bound to the metal complex is also important in catalysis or the implementation of chemical sensors. When investigating these binding mechanisms, scientists use porphyrin rings with a central cobalt or iron atom. They coat a copper or silver support surface with these substances. An important...

A myriad of methods for watching water molecules in motion advances critical understanding of biology, chemistry and climate science Water (H2O) is a unique molecule that holds amazing properties. Scientists have a good grasp of the structure and chemistry of individual molecules of water. But understanding how large numbers of these molecules move and interact--within bulk liquid water, or at the interface between water and air--is much more complicated. Theoretical chemist James Skinner, at...

UC Riverside chemists study quadrupedal molecular machines to provide an answerMolecular machines can be found everywhere in nature, for example, transporting proteins through cells and aiding metabolism. To develop artificial molecular machines, scientists need to understand the rules that govern mechanics at the molecular or nanometer scale (a nanometer is a billionth of a meter).To address this challenge, a research team at the University of California, Riverside studied a class of...

An octopus-like polymer can "walk" along the wall of a narrow channel as it is pushed through by a solvent. Now research in The Journal of Chemical Physics, which is published by the American Institute of Physics, provides a theoretical model that compares the transport characteristics of straight- and branched-chain polymers in smooth channels as well as in channels whose walls interact with the polymer -- work that could aid in the development of carrier molecules for delivering drugs at a...

An international collaboration led by chemists and engineers from the University of Pennsylvania has prepared a library of synthetic biomaterials that mimic cellular membranes and that show promise in targeted delivery of cancer drugs, gene therapy, proteins, imaging and diagnostic agents and cosmetics safely to the body in the emerging field called nanomedicine. The study appears in the current issue of the journal Science. The research provides the first description of the preparation,...

Small, smaller, "nano" data storage! Interest is growing in the use of metallofullerenes "“ carbon "cages" with embedded metallic compounds "“ as materials for miniature data storage devices. Researchers at Empa have discovered that metallofullerenes are capable of forming ordered supramolecular structures with different orientations. By specifically manipulating these orientations it might be possible to  store and subsequently read out information. Carbon exists in the form...

An international team of researchers from the Netherlands, Russia and Austria discovered that monolayer coverage and channel length set the mobility in self-assembled monolayer field-effect transistors (SAMFETs). This opens the door to extremely sensitive chemical sensors that can be produced in a cost-effective way. The research was done at Philips Research Eindhoven and Eindhoven University of Technology. The findings were published as an Advanced Online Publication in Nature...

Our cells are controlled by billions of molecular "switches" and chemists at UC Santa Barbara have developed a theory that explains how these molecules work. Their findings may significantly help efforts to build biologically based sensors for the detection of chemicals ranging from drugs to explosives to disease markers.Their research is described in an article published this week in the Proceedings of the National Academy of Sciences (PNAS).Biosensors are artificial molecular switches that...
