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.

An amperometric biosensor for the galactose measurement was developed by immobilizing galactose oxidase (GAO) on a Nafionmodified thin film platinum electrode. The working electrode with a disk shape and the surrounding ring shaped counter electrode were both fabricated by the thin film technology. They were integrated onto the same microchip. The effects of pH, buffer compositions, and temperature on the biosensor response were investigated. The optimum pH range for the sensor was located between 7.2 to 7.8, and the linear response range was from 0.10 mM to 8.0 mM. The apparent Michaelis-Menten constant ðK app M Þ value was 29.1 mM. It was observed that some possible interferences from the ascorbic acid, uric acid, sucrose, and glucose were reduced due to the permselectivity of Nafion film. A stable performance of more than one month has been demonstrated on this biosensor.

An amperometric multianalyte biosensor for the simultaneous determination of glucose and galactose was developed based on chamber-type electrodes, which were fabricated by micromachining technology. The dual chamber-type enzyme electrode with glucose and galactose sensor elements was integrated onto one microchip. The experimental parameters of this biosensor were optimized. The biosensor exhibited a linearity of up to 4.0 mom for glucose and 4.5 mom for galactose, and the response time was about 30 s for glucose and 40 s for galactose. No cross-talking behavior was investigated in the c o m e of simultaneous measurement of the two analytes. Interference from elecbmactive species, such as ascorbic acid .and uric acid, was minimized due to the permselectivity of Nafion film. In addition, the biosensor displayed a storage stability of longer than one month.
