The role of enzyme engineering in biotechnology, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of amylase and protease on to manganese ferrite (MnFe2O4). The metal ferrite was synthesized via a sol – gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnet...

Over the past decade, transition metal-based ferrite nanostructures, displaying MFe2O4 stoichiometry (M2+ cations, e.g., Mn, Co, Ni and Zn), have been devised examined primarily owing to their promising applications in cancer nanomedicine. Among these multi-functional spinel ferrites, manganese (MnFe2O4) deserves special attention because it unveils exciting magnetic properties, high chemical s...

Hitherto, a considerable amount of research has been carried out to investigate the equilibrium condition adsorption process; nevertheless, there is no comprehensive study evaluate surface properties MOFs. Therefore, mechanism and capacity MOFs have not fully understood. Furthermore, mass transfer still unknown so it possible predict process using In this work, new metal–organic framework (MOF)...

Smart drug delivery nanosystem is significant for tumor treatments due to its possibility of temporally, spatially, and dose-controlled release. However, the therapeutic efficacy often compromised in cancer treatment as enrichment agents reticuloendothelial system. Herein, doxorubicin (DOX) loaded biomimetic with macrophage cell membrane (MCM) camouflaged, MnFe2O4-DOX-MCM nanocube (NC), develop...

Manganese ferrite (MnFe2O4) has been successfully synthesized by using coprecipitation methods with a various particles size of 13.1, 13.8, 16.2, 18.1, and 18.4 nm. Analysis of crystal structure properties which has been carried out by using XRD (X-Ray Diffraction) method revealed that all samples belong to cubic spinel structure. The measurement used computerized impedance spectroscopy system ...
