Researchers from which university has developed microscope for surgery without cutting skin ?

Group of researchers from the University of British Columbia (UBC) has developed the microscope for performing surgery without cutting skin. It was published in the journal "Science Advances" titled "Precise closure of single blood vessels via multiphoton absorption-based photothermolysis".The device is a specialized type of multiphoton excitation microscope that allows imaging of living tissue up to about one millimeter in depth using an ultrafast infrared laser beam, that can both scan skin and perform surgery by intensifying the heat its beam produces.
