Malaria is a dangerous tropical disease, with high morbidity in developing countries. The responsible parasite has developed resistance to the existing drugs; therefore, new drug delivery systems are being studied increase efficacy by targeting hemozoin, paramagnetic metabolite. Herein, magnetic mesoporous silica (magMCM) was synthesized using iron oxide particles dispersed structure for magnetically driven behavior. X-ray diffractogram (XRD) and Mössbauer spectra show patterns corresponding...
A mesoporous, magnetic, and hydrophobic material was designed step by to act as a support for lipase immobilization. Its pore size (8.0 nm) is compatible with the of from Thermomyces lanuginosus (TLL), its surface (contact angle water drop = 125°) planned interact on interfacially activated form (open conformation). The presence magnetite particles provides magnetic retrieval enables recyclability biocatalysts. Regarding immobilization parameters, tested in comparison unmodified hydrophilic...
Abstract Silica hollow spheres are obtained as micro‐sized containers with magnetic‐field‐induced mobility. The completely empty proved accessible features of confined environment, where an unexpected structured fluorescence emission large Stokes' shift is observed. This multifunctional system achieved through a controllable etching magnetite from magnetite@silica core–shell hydrochloric acid solution, resulting in silica coupled remaining magnetite@silica. increase the time leads to...
