| Abstract Scope |
Healthcare-associated infections remain a significant source of patient morbidity and mortality. This presentation considers four approaches to create thin films for antimicrobial applications. Pulsed laser deposition (PLD) involves the use of high-energy laser pulses to ablate a target, enabling the deposition of antimicrobial thin films with controlled thickness on medically relevant substrates. Matrix-assisted pulsed laser evaporation involves the adaptation of PLD for heat-sensitive pharmaceutical agents; this approach involves laser evaporation of a frozen solvent-based target at fluences of 0.05–0.25 J/cm². Atomic layer deposition (ALD), which involves a series of self-limiting precursor exposures, was used to deposit antimicrobial thin films on surfaces with complex geometries. Plasma-enhanced chemical vapor deposition (PECVD) was used to deposit silicon-doped diamond-like carbon (Si-DLC) thin films at ambient substrate temperature; argon and oxygen plasma post-treatments were used to modify the surface chemistry and wettability. Chemical and biological characterization of these thin films will be considered. |
