Abstract Scope Laparoscopes are prone to fogging, which can lead to a limited field of view during surgical procedures. Previous studies of diamond-like carbon (DLC) coatings found doping the films with SiO improved hydrophilic qualities, suggesting their possible use as antifogging coatings for laparoscopes. For this study, a group of DLC films doped with SiO were produced by pulsed laser deposition to test their biocompatibility and stability. The films’ hydrophilicity, transparency, and biocompatibility properties were characterized. The films were transparent and demonstrated hydrophilic qualities. Samples subjected to argon etching had contact angles under 5 degrees. Biocompatibility of the films was assessed through cellular assays and results were statistically similar to the control. Simulated body fluid soaks were performed to test film stability and no delamination was observed. The results of this research show promise for DLC as an antifogging coating for laparoscopes.
