3D Printed Polylactic Acid Well-Plate for Multi-enzyme Immobilization

Methods Mol Biol. 2022:2487:163-175. doi: 10.1007/978-1-0716-2269-8_10.

Abstract

3D printing is lately utilized in biological sciences under the scope to develop customized scaffolds that will host biomolecules, either whole cells or parts of them, like enzymes. In the present work, we present a protocol to modify the surface of 3D printed polylactic acid (PLA) well-plates with the aim to co-immobilize multiple enzymes that will perform cascade reactions. Detailed steps to design and print the final models are described. The developed protocol for surface modification is based on coating with chitosan biopolymer and covalent immobilization of the enzymes β-glucosidase, glucose oxidase, and peroxidase via glutaraldehyde cross-linking. Enzymatic activity measurements indicative of the catalytic performance of the system are also presented.
