Abstract :
This work investigates the use of continuous-wave and femtosecond-pulsed modes of a laser to obtain different functionalities when interacting with living cells using a single, simple, optical setup. This study demonstrates that careful control of the laser source in both spatial and/or temporal aspects of the output beam can offer major advantages in enhanced functionality and ease of use of fs-optical transfection systems. The results of this study are applicable in systems where fs-lasers are being utilized in applications that rely on nonlinear effects.
