Real time imaging of femtosecond laser induced nano-neurosurgery dynamics in C. elegans

In this study we present for the first time the use of confocal microscopy and laser scanning brightfield microscopy (LSBF) for real time imaging of femtosecond laser nanosurgery and its dynamics in C. elegans. A single multimodal optical workstation that provides the ability to perform femtosecond laser nanosurgery and simultaneous confocal and LSBF imaging was used for the purpose. With this tool several dynamic phenomena concomitant with laser nanosurgery in C. elegans were observed and imaged. Some of these dynamic phenomena, like muscular contraction and single muscle cell stimulation, have been imaged for the first time during nano-neurosurgery of C. elegans.
