Abstract
Bacterial keratitis, a vision-threatening corneal infection, can rapidly progress without the proper treatment, currently consisting of high frequency antibiotic eyedrop application. We aim to develop a more efficient pulsed plasmonic laser photoablation (PPLP) based therapy utilizing the unique optical properties of gold nanoparticles and the active targeting of Pseudomonas aeruginosa, a common cause of keratitis. The resulting immunogold bioconjugate nanoparticles were characterized based on size and zeta potential analysis. The efficiency of attachment to bacterial cells was investigated by varying the nanoparticle-to-bacteria ratio and incubation temperature. Nanoparticle attachment to the surface of bacteria was quantified using spectroscopy and microscopy techniques.
