Researchers at Purdue University have developed a scanning-laser-based technology for real-time precision control of molecular activities and chemical processes in live cells. Current technologies do not allow for automated and selective control of laser-target interactions based on chemical compositions. The Purdue technology automatically detects optical signals from biological molecules to trigger the control laser beam in real-time; the control laser beam is only activated at the pixels when the chemical-selective optical signals are sensed. This technology functions in real-time and effectively controls molecular targets in highly-dynamic living samples. It can be integrated with fluorescence or other types of laser scanning microscopes.

Technology Validation: The technology has diffraction-limited image resolution and opto-control precision (200-500 nm). Chemical-selective signals from fluorescence or Raman can be used to trigger the opto-control laser beam. The response time of the feedback loop is ~20-30 ns.
