“…As an example, isocyanide functional groups were introduced on the surface of poly(ethylene terephthalate), Dacron 99, through Passerini-3CR, and then the trypsin or urease enzymes were covalently attached to the surface of Passerini-functionalized polyesters containing isocyanide scaffolds by the utilization of Ugi-4CR method in an aqueous buffer at neutral pH in the presence of acetaldehyde 100 and excess acetate 101, as described by Goldstein et al (Scheme 32). 125 Polyacrylamide. To check the reactivity of the functionalized polyacrylamides as a missing part of MCR, Axen and coworker reported an efficient procedure for the synthesis of Ugifunctionalized polyacrylamide structures.…”

The emergence of neoteric synthetic routes for materials functionalization is an interesting phenomenon in materials chemistry. In particular, the union of materials chemistry with multicomponent reactions (MCRs) opens a new avenue leading to the realm of highly innovative functionalized architectures with unique features. MCRs have recently been recognized as considerable part of the synthetic chemist's toolbox due to their great efficiency, inherent molecular diversity, atom and pot economy along with operational simplicity. Also, MCRs can improve E-factor and mass intensity as important green chemistry metrics. By rational tuning of the materials, as well as the MCRs, wide ranges of functionalized materials can be produced with tailorable properties that can play important roles in the plethora of applications. To date, there has not reported any exclusive review of a materials functionalization with MCRs. This critical review highlights the state-of-the-art on the one-pot functionalization of carbonaceous and siliceous materials, polysaccharides, proteins, enzymes, synthetic polymers, etc., via diverse kind of MCRs like Ugi, Passerini, Petasis, Khabachnik-Fields, Biginelli, and MALI reactions through covalent or noncovalent manners. Besides the complementary discussion of synthetic routes, superior properties and detailed applicability of each functionalized material in modern technologies are discussed. Our outlook also emphasizes future strategies for this unprecedented area and their use as materials for industrial implementation. With no doubt, MCRs-functionalization of materials bridges the gap between materials science domain and applied chemistry.

“…Stacks of such filters exhibited no significant compaction or pressure drop effects. Aminoaryl functional groups were introduced on the filter fabric by procedures described in earlier communications from our laboratory, [16][17][18][19] and urease bound to the modified filter fabric by the azo method. Multilayer filter reactors constructed by packing varying numbers of urease-nylon filters in a column could be operated in a wide range of substrate concentrations and flow rates under conditions where the kinetics of the reaction dominate the catalytic process.…”

Urease was bound to commercially available nonwoven nylon fabric filters. Multilayer immobilized-enzyme filter reactors were constructed by packing varying numbers of urease-nylon filters in a column. Owing to the relatively open structure and high mechanical strength of the filter fabric, compaction and pressure drop effects were minimal. The reactors could be operated in a wide range of substrate concentrations and flow rates under conditions where mass-transfer limitations could be neglected. The kinetic behavior of the immobilized-enzyme filter reactors could be described by a linear form of the integrated Michaelis-Menten equation using a model based on the sequential action of the enzyme filters.
