Reactive Green 5-Decorated Polyacrylamide/Chitosan Cryogel: An Affinity Matrix for Catalase.

Acrylamide/chitosan-based cryogel was fabricated, and a triazine dye, Reactive Green 5, was attached to the cryogel by nucleophilic substitution to build a dye affinity support for adsorption of catalase enzyme. Characterization of cryogel was performed using FTIR, SEM, EDX, BET, and swelling test. Synthesized cryogel beared pores with ~ 200 μm in size and the surface area of 11.

Covalent immobilization of papain onto poly(hydroxyethyl methacrylate)-chitosan cryogels for apple juice clarification.

Enzyme immobilization appears as a remarkable technique to safely attach enzymes for several applications and cryogels stand as promising support materials to be used in such investigations. In this work, papain enzyme was immobilized onto an interpenetrating network obtained by cryogelation of N,N'-methylenebisacrylamide cross-linked 2-hydroxyethyl methacrylate and glutaraldehyde cross-linked chitosan. Cryogels were modified with -NH functionality and glutaraldehyde in order to attach papain covalently.

Molecularly imprinted cryogels for carbonic anhydrase purification from bovine erythrocyte.

Molecularly imprinted PHEMAH cryogels were synthesized and used for purification of carbonic anhydrase from bovine erythrocyte. Cryogels were prepared with free radical cryopolymerization of 2-hydroxyethyl methacrylate and methacryloylamido histidine and characterized by swelling degree, macroporosity, FTIR, SEM, surface area and elemental analysis. Maximum carbonic anhydrase adsorption of molecularly imprinted PHEMAH cryogel was found to be 3.

5-amino-2-mercapto-1,3,4-thidiazole modified single-use sensors for electrochemical DNA analysis.

In this study, single-use graphite electrodes modified with 5-amino-2-mercapto-1,3,4-thidiazole (AMT) were fabricated for electrochemical monitoring of DNA. The surfaces of AMT modified pencil graphite electrodes (PGEs) were characterized by scanning electron microscopy (SEM). Electrochemical behaviors of these electrodes were investigated using differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS).
