Image Credit: Freie Universität Berlin/the Ewers Group A research team led by biochemist Professor Helge Ewers from Freie Universität Berlin has developed a new technique for the light-mediated release and investigation of proteins in live cells. The technique makes use of a laser pulse to control the release of tagged protein molecules within a cell, allowing for the molecules' function to be more clearly observed. The team believes that this method has a wide variety of potential applications in future scientific research. The study, titled "An Optogenetic Method for the Controlled Release of Single Molecules" has been published in the scientific journal Nature Methods ( '024 -02204-x ). At the simplest level, proteins can be understood as tiny machines - a mere millionth of a millimeter in size - that are responsible for carrying out the majority of functions in our cells.
