A research group at Umeå University has developed new advanced light-controlled tools that enable precise control of proteins in real time in living cells. This groundbreaking research opens doors to new methods for studying complex processes in cells and could pave the way for significant advances in medicine and synthetic biology.

“Cellular processes are complex and constantly change depending on when and where in the cell they occur. Our new chemical tool with light switches will make it easier to control processes in the cell and study how cells function in real time. We can also determine where we make such regulation with a resolution of micrometres within a cell or tissue”, says Yaowen Wu, professor at the Department of Chemistry and SciLifeLab Group leader at Umeå University.
