Electron Spin Resonance

Authors: George Rajna

Australian scientists have developed a new tool for imaging life at the nanoscale that will provide new insights into the role of transition metal ions such as copper in neuro-degenerative diseases. [22] Scientists have developed a camera that can see through the human body. [21] A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue—such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing. [20] Chemists at ITbM, Nagoya University have developed a super-photostable fluorescent dye called PhoxBright 430 (PB430) to visualize cellular ultra-structure by super-resolution microscopy. [19] Dipole orientation provides new dimension in super-resolution microscopy [18] Fluorescence is an incredibly useful tool for experimental biology and it just got easier to tap into, thanks to the work of a group of University of Chicago researchers. [17] Molecules that change colour can be used to follow in real-time how bacteria form a protective biofilm around themselves. This new method, which has been developed in collaboration between researchers at Linköping University and Karolinska Institutet in Sweden, may in the future become significant both in medical care and the food industry, where bacterial biofilms are a problem.
