The therapeutic protein superoxide dismutase (SOD) was encapsulated into PCADK-based microparticles using a double emulsion procedure, and these microparticles dramatically enhanced the efficacy of SOD in cell culture experiments with macrophages. The widely studied enzyme-based sensors were fabricated by immobilizing copper–zinc superoxide dismutase (Cu–Zn SOD) onto the electrode surface (Kim et al., 2012). However, the electron transfer between SOD and electrode is very difficult because of the deeply buried redox centers of SOD and its unfavorable orientations (Wang et al., 2012).

The objective of this study is to improve the blood compatibility of polysulfone (PSF) based hemodialysis membranes through generating antioxidative surfaces with superoxide dismutase (SOD)/catalase (CAT) enzyme couple immobilization.

10-5-2011 · Although the field of islet transplantation has progressed dramatically, the necessity of life-long immunosuppressive drugs greatly limits the wide availability of this promising therapy as an alternative to exogenous insulin. The benefits obtained from islet transplantation must clearly outweigh the immunosuppressive and surgical related risks.

A new polymer composition was developed based on hybrid sol-gel material for the immobilization of enzymes on the surface of screen-printed carbon electrodes modified with Prussian blue. The existing... In this study, superoxide dismutase (SOD)–catalase (CAT) enzyme mixture was immobilized onto the polysulfone membranes by modifying and activating the surface with PEI deposition or plasma treatment. To compare kinetic parameters, both enzymes were also immobilized individually thus a total of 6 membranes were prepared .
