Anti‐Acanthamoeba Activities of Silica Nanoformulated Quercetin Compound Derived From Annona muricata L. Leaves

Scientifica, Volume 2026, Issue 1, 2026.
Acanthamoeba spp., free‐living amoebae (FLA), are the causative agents of Acanthamoeba keratitis (AK) and granulomatous amoebic encephalitis (GAE). These diseases have limited treatment options; therefore, drug discovery remains a critical priority. This study evaluated the leaf extract of Annona muricata L., which contains quercetin, formulated in ...

Determination of Polyhexamethylene Biguanide Utilizing a Glucose Oxidase Enzymatic Reaction

Analytical Sciences, 2019
Polyhexamethylene biguanide (PHMB) is a cationic disinfectant widely used for personal-care products and for sanitizers in swimming pools. This paper describes a promotion effect of PHMB on a glucose oxidase (GOx) enzymatic reaction with ferricyanide ion and its analytical application. The promotion effect arose from a polyion complex formation between
