Immobilization of catalase on membranes of poly(ethylene)‐g‐co‐acrylic acid and poly(tetrafluoroethylene)‐g‐co‐acrylic acid and their application in hydrogen peroxide electrochemical sensors

Abstract: The immobilization of catalase on grafted membranes of poly(ethylene)‐g‐co‐acrylic acid and poly(tetrafluoroethylene)‐g‐co‐acrylic acid and their application in hydrogen peroxide electrochemical sensors is described. The introduction of carboxylic acid groups onto a hydrophobic support provides a good environment for subsequent enzyme immobilization. This single membrane, hydrogen peroxide sensor showed significant improvement with respect to the double membrane versions. The response is very rapid, the linear… Show more

“…In these cases, the material jetting process and FFF technology are the most used in manufacturing these polymeric-based systems due to their affordability, availability, and ease of use. The conjugation of 3DP technology with wastewater and drug delivery systems allows the design of complex polymer-based structures in which the physical cues can induce functionality that in the last century could only achieved by chemical modification with hazardous reagents and radiation [11][12][13]. These finely tuned geometries and topographies make it possible to customize physical properties and prompt adjustable sorption/diffusion profiles due to differences in surface area, surface roughness, and volume.…”

“…Polymeric materials are easier to modify due to their properties and available processing techniques, which become advantageous for their use in several areas, including for biomedical applications [5]. Nevertheless, some polymers need long routes to be chemically modified in order to present the appropriate surface chemistry for interaction with biological compounds, an approach that has been used for a long time [6][7][8].…”

“…The development of functionalized materials, especially polymers, for use in biomedical applications started long ago, before the development of the designed biomedical application of materials. The goal could be, for example, to create the appropriate functional groups that allowed the immobilization of biological molecules for biosensors development [1,2,3]. Usually, the functionalization step was made after the conformation stage and involved chemical processing [4].…”
