Spatiotemporally precise control over complex biological processes in live cells is a long-sought-after goal for researchers. Currently, limited methodologies exist that have the chemical selectivity, spatial precision, or temporal response needed to image and manipulate dynamic biological processes simultaneously. We develop a novel technology, real-time precision opto-control (RPOC), that uses the optical signal generated during laser scanning imaging to activate lasers and control the chemical processes only at the desired pixel locations. We demonstrate the ability of RPOC to precisely manipulate cellular dynamics and as a versatile microsurgery platform for biological applications using a femtosecond laser source.
