“…Doping various elements is an effective method to adjust the electronic structure and surface chemical reactivity of CDs. 43,58 Studies have shown that nitrogen-doped CDs have good antibacterial activity. They produce ROS in bacterial cells by simulating the activities of POD-like enzymes and OXD-like enzymes, thus killing bacteria in a short time.…”

“…Li et al synthesized N,Fe-codoped carbon quantum dots (N,Fe-CQDs) using β-CD, ferric chloride, and ethylenediamine through a convenient one-step green hydrothermal route. 103 The N,Fe-CQDs revealed higher catalytic activity in comparison with horseradish peroxidase (HRP), which produced an apparent color change in the presence of H 2 O 2 for 3,3′,5,5′-tetramethylbenzidine. Therefore, efficient, sensitive, and selective colorimetric GM has been reported via the N,Fe-CQDs as simulated peroxidase to detect produced H 2 O 2 as a result of glucose oxidation with GOx.…”

Diabetes mellitus is a prevalent chronic health condition that has caused millions of deaths worldwide. Monitoring blood glucose levels is crucial in diabetes management, aiding in clinical decision making and reducing the incidence of hypoglycemic episodes, thereby decreasing morbidity and mortality rates. Despite advancements in glucose monitoring (GM), the development of noninvasive, rapid, accurate, sensitive, selective, and stable systems for continuous monitoring remains a challenge. Addressing these challenges is critical to improving the clinical utility of GM technologies in diabetes management. In this concept, cyclodextrins (CDs) can be instrumental in the development of GM systems due to their high supramolecular recognition capabilities based on the host–guest interaction. The introduction of CDs into GM systems not only impacts the sensitivity, selectivity, and detection limit of the monitoring process but also improves biocompatibility and stability. These findings motivated the current review to provide a comprehensive summary of CD-based blood glucose sensors and their chemistry of glucose detection, efficiency, and accuracy. We categorize CD-based sensors into four groups based on their modification strategies, including CD-modified boronic acid, CD-modified mediators, CD-modified nanoparticles, and CD-modified functionalized polymers. These findings shed light on the potential of CD-based sensors as a promising tool for continuous GM in diabetes mellitus management.

“…Nanozymes are composed of nanoparticles of inorganic materials possessing intrinsic enzymatic activities. Nanozymes have been developed with nanoparticle forms of Fe 3 O 4 , [ 16 ] platinum, [ 108 ] gold, [ 109,110 ] copper oxide, [ 111 ] CoFe 2 O 4 , [ 112 ] graphene oxide, [ 113 ] carbon, [ 114 ] among others. Besides classifying the nanozymes based on the type of enzymatic reactions they mimic, [ 115 ] they may also be categorized based on their atomic composition, which largely determine their catalytic activity and specificity in operation.…”

Wireless nano‐/micromotors powered by chemical reactions and/or external fields generate motive forces, perform tasks, and significantly extend short‐range dynamic responses of passive biomedical microcarriers. However, before micromotors can be translated into clinical use, several major problems, including the biocompatibility of materials, the toxicity of chemical fuels, and deep tissue imaging methods, must be solved. Nanomaterials with enzyme‐like characteristics (e.g., catalase, oxidase, peroxidase, superoxide dismutase), that is, nanozymes, can significantly expand the scope of micromotors’ chemical fuels. A convergence of nanozymes, micromotors, and microfluidics can lead to a paradigm shift in the fabrication of multifunctional micromotors in reasonable quantities, encapsulation of desired subsystems, and engineering of FDA‐approved core–shell structures with tuneable biological, physical, chemical, and mechanical properties. Microfluidic methods are used to prepare stable bubbles/microbubbles and capsules integrating ultrasound, optoacoustic, fluorescent, and magnetic resonance imaging modalities. The aim here is to discuss an interdisciplinary approach of three independent emerging topics: micromotors, nanozymes, and microfluidics to creatively: 1) embrace new ideas, 2) think across boundaries, and 3) solve problems whose solutions are beyond the scope of a single discipline toward the development of micro‐bio‐chemo‐mechanical‐systems for diverse bioapplications.
