Highly sensitive and integrated optical multi-band CO2 sensors are significant at the shortwave infrared (SWIR) region still lack research. A compact sensor composed of a Au-disk/TiO2-cylinder/Au-film metasurface coated by polyhexamethylene biguanide (PHMB) film, functioning resonances as well having high sensitivity to gas concentrations, is presented. It can be employed dual-band narrowband a...

PURPOSE To establish polyhexamethylene biguanide (PHMB) as an effective treatment for Aspergillus keratitis in a novel murine model. To determine the ability of the calcineurin inhibitors tacrolimus (FK506) and cyclosporine A (CSA) to enhance the activity of PHMB, amphotericin B (AMB), and voriconazole (VCZ) against Aspergillus keratitis. METHODS IN VITRO STUDIES Broth antifungal susceptib...

IMPORTANCE Acanthamoeba keratitis is a debilitating eye disease that requires effective topical drug therapy. Currently, there is no standard in vitro test to evaluate anti-Acanthamoeba drugs. OBJECTIVE To develop a practical in vitro complete-kill assay to assess anti-Acanthamoeba drugs. DESIGN AND SETTING Isolates of Acanthamoeba strains (n = 15) evaluated in a clinical laboratory. An in ...
