Chemical Impact Parameter

Authors: George Rajna

Scientists at the University of Toronto have found a way to select the outcome of chemical reaction by employing an elusive and long-sought factor known as the 'impact parameter'. [31] Tailor-made protein drugs in the fight against cancer and other diseases are a step close, with the Centre for NanoScale Science and Technology at Flinders playing a part in one of the latest chemistry discoveries in effectively modifying therapeutic proteins. [30] New research published in Nature Methods will dramatically improve how scientists "see inside" molecular structures in solution, allowing for much more precise ways to image data in various fields, from astronomy to drug discovery. [29] Prof WANG Zhisong and his research team from the Department of Physics, NUS have developed two sets of conceptually new mechanisms that enable artificial nanowalkers to move in a self-guided direction using their internal mechanics. [28] Gene editing is one of the hottest topics in cancer research. A Chinese research team has now developed a gold-nanoparticle-based multifunctional vehicle to transport the "gene scissors" to the tumor cell genome. [27] Cells can be programmed like a computer to fight cancer, influenza, and other serious conditions – thanks to a breakthrough in synthetic biology by the University of Warwick. [26] This "robot," made of a single strand of DNA, can autonomously "walk" around a surface, pick up certain molecules and drop them off in designated locations. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.
