Paper Abstract

Bacterial related infections are a burden on the healthcare industry. A system was built to test the efficacy of laser generated shockwaves on S. epidermidis biofilms (RP62A) grown on polystyrene surfaces. The system is based on a Qswitched, ND:YAG pulsed laser with an output wavelength of 1.064 μm that ablates titanium-coated soda-lime glass. Results show that the system is capable of generating stress profiles that can effectively delaminate biofilm structures from polymer surfaces.
