Adsorption behavior and activity of horseradish peroxidase onto polysaccharide-decorated particles

Carbon paste electrode modified with pine kernel peroxidase immobilized on pegylated polyurethane nanoparticles

“…Furthermore, the electrode (b) containing only peroxidase showed a lower response than electrode (d). These results were expected since the enzyme immobilization on a polymeric support improves its activity and stability [22,24].…”

“…In this work, the enzyme immobilization was performed at pH 6.5, which is the optimum pH of peroxidase [22]. Under such condition, the pegylated polyurethane nanoparticles are negatively charged, as evidenced by zeta potential value described on a previous work [21].…”

Studies on the activity and stability of immobilized horseradish peroxidase on poly(ethylene terephthalate) grafted acrylamide fiber

“…This allows the biocatalyst to survive longer during process conditions and allows one to operate the process at higher temperature [3]. There are many immobilization techniques available such as adsorption [4], covalent attachment [5] and entrapment [6]. Non-covalent binding processes are simple but have the disadvantage of weak binding of enzyme.…”

Lectins and/or xyloglucans/alginate layers as supports for immobilization of dengue virus particles

“…These derivatives are potential supports for biomedical applications due to their biocompatibility and their role in many recognition processes. Complex and variable structures, molecular recognition and specific binding between polysaccharides and proteins open a large field for biosensors and bioassays design [4][5][6][7][8][9][10][11][12][13][14].…”
