Enzymes are attractive as catalysts due to their specificity and biocompatibility; however, use in industrial biomedical applications is limited by stability. Here, we present a facile approach for enzyme immobilization within "all-enzyme" hydrogels forming photochemical covalent cross-links between the glucose oxidase. We demonstrate that mechanical properties of hydrogel can be tuned with concentration data suggests dimeric nature oxidase results unusual gel formation behavior which degree forced induced dimer dissociation unfolding. confirm quantify activity using Trinder assay 1D modeling show 50% enzymatic retained experimental shows Michaelis constant KM upon formation. These observed effects may forces experienced individual nanoscale enzymes during mesoscale network have therefore demonstrated cross-linking readily employed produce functional all-enzyme easily tunable specific catalytic activity. This provides enormous potential producing biocatalytic materials properties, responsive biological functionality high volumetric productivity inform future design devices enhanced sensitivity

Pectin is a complex polysaccharide of great importance to food, pharmaceutical and cosmetic industries. It widely used in the food industry as thickener, gelling agent an emulsifier among others. also exhibits potential anti-inflammatory immunomodulatory effects. Its functional properties are determined by characteristics such neutral sugar side chains, molecular weight degree methyl-esterification. Human beings unable digest pectin therefore pectinases catalyze degradation pectic substances. This review focuses on pectin, its composition, application those enzymes involved degradation, different agro-industrial residues sources extraction methods future perspectives.

Enzymes are outstanding (bio)catalysts, not solely on account of their ability to increase reaction rates by up several orders magnitude but also for the high degree substrate specificity, regiospecificity and stereospecificity. The use development enzymes as robust biocatalysts is one main challenges in biotechnology. However, despite specificities turnover enzymes, there drawbacks. At industrial level, these drawbacks typically overcome resorting immobilized enhance stability. Immobilization allows reuse, increases stability, facilitates process control, eases product recovery, enhances yield quality. This especially important expensive those obtained low fermentation with relatively activity. review provides an integrated perspective (multi)enzyme immobilization that abridges a critical evaluation methods carriers, biocatalyst metrics, impact key carrier features performance, trends towards miniaturization detailed illustrative examples representative biocatalytic applications promoting sustainability.

Abstract Biocatalysis is an established chemical synthesis technology that has by no means been restricted to research laboratories. The use of enzymes for organic evolved greatly from early development proof‐of‐concept – small batch production industrial scale. Different enzyme immobilization strategies contributed this success story. Recently, the hydrogel materials attracting great interest. Within review, we pay special attention recent developments in key emerging field research. Firstly, will briefly introduce concepts both biocatalysis and worlds. Then, list interesting publications link concepts. Finally, provide outlook comment on future perspectives further exploration hydrogels.

Three-dimensional (3D) printed electrochemical devices are increasingly used in point-of-need and point-of-care testing. They show several advantages such as simple fabrication, low cost, fast response, excellent selectivity sensitivity small sample volumes. However, there only a few examples of analytical combining 3D-printed electrodes with electrochemiluminescence (ECL) detection, an detection principle widely employed clinical chemistry analysis. Herein, portable, miniaturized ECL biosensor for glucose has been developed, based on the luminol/H2O2 system employing two-electrode configuration carbon black-doped polylactic acid (PLA) electrodes. The emission is obtained by means 1.5V AA alkaline battery detected using smartphone camera, thus providing easy portability platform. was successfully applied sensing H2O2 and, upon coupling enzyme oxidase, detection. incorporation luminol oxidase agarose hydrogel matrix allowed to produce preloaded reagents required assay, so that analysis addition. showed ability detect up 5 mmol L−1, limit 60 μmol L−1. also analyse real samples (i.e., saline solutions artificial serum samples) satisfactory results, suggesting its suitability Coupling other oxidases could further extend applicability this
