“…This electrochemical model with the lectin immobilized in the MOF for the construction of a biosensor has also been verified by Carvalho et al [54] for evaluating the results of the electrochemical potentials related to the interaction of Cramoll immobilized in an MOF with different concentrations of glucose. The combination of lectins with semiconductors, such as metallic polymers, increases their recognition capacity in biosensors [56].…”

“…In order to build a biosensor to detect dye residues in samples after electrocoagulation with aluminum batteries, cMoL was used to aggregate MOF crystals on a platinum electrode surface, providing stability for the use of this device. This aggregate effect was also verified with Cramoll lectin on the surface of a gold electrode containing an MOF (54).…”

“…The efficiency of cMoL immobilization in the metal-organic structure [Cu 3 (BTC) 2 (H 2 O) 3 ] n contributed to the stability of the biosensor, thus facilitating the electrochemical potentials and showing that the use of an electrochemical system with a modified working electrode can be applied to study the interaction of cMoL with galactose. The biological performance of lectin correlating structural modifications and surface charge distribution was elucidated by potentiometry [54]. This redox electroactivity can reveal data characteristics of the equilibrium state through electrochemical methods; the application interface with electrical charges, adsorbed on the surface of the electrode, can be evaluated in a simplified way [32].…”

Triturated Moringa oleifera seeds have components that adsorb recalcitrant indigo carmine dye. Coagulating proteins known as lectins (carbohydrate-binding proteins) have already been purified from the powder of these seeds, in milligram amounts. The coagulant lectin from M. oleifera seeds (cMoL) was characterized by potentiometry and scanning electron microscopy (SEM) using MOFs, or metal–organic frameworks, of [Cu3(BTC)2(H2O)3]n to immobilize cMoL and construct biosensors. The potentiometric biosensor revealed an increase in the electrochemical potential resulting from the Pt/MOF/cMoL interaction with different concentrations of galactose in the electrolytic medium. The developed aluminum batteries constructed with recycled cans degraded an indigo carmine dye solution; the oxide reduction reactions of the batteries generated Al(OH)3, promoting dye electrocoagulation. Biosensors were used to investigate cMoL interactions with a specific galactose concentration and monitored residual dye. SEM revealed the components of the electrode assembly steps. Cyclic voltammetry showed differentiated redox peaks related to dye residue quantification by cMoL. Electrochemical systems were used to evaluate cMoL interactions with galactose ligands and efficiently degraded dye. Biosensors could be used for lectin characterization and monitoring dye residues in environmental effluents of the textile industry.

Coagulant lectin from Moringa oleifera seeds (cMoL) was characterized by potentiometry and scanning electron microscopy (SEM) using MOF, Metal-Organic Frameworks of [Cu3(BTC)2.H2O)3]n, to immobilize cMoL and construct biosensors. Developed aluminum-air batteries degraded indigo carmine dye formulated similar to a textile effluent; biosensors investigated cMoL interaction with specific galactose and monitored residual dye. SEM revealed components of electrode assembly steps. Oxide reduction reactions of batteries generated Al(OH)3 promoting dye electrocoagulation. Cyclic voltammetry showed differentiated redox peaks related to dye residue quantification by cMoL. Electrochemical systems evaluated cMoL interaction with ligand and efficiently degraded dye; biosensors could be used for lectin characterization and monitoring dye residues in environmental textile effluents.

MOF-Based Materials for Glucose Detection

et al. 2023

View full text Add to dashboard Cite

Metal–organic frameworks (MOFs), constructed by coordination between metal-containing nodes and organic linkers, are widely used in various fields due to the advantages of tunable pores, diverse functional sites, stable structure, and multi-functionality. It should be noted that MOF-based materials play a major role in glucose detection, serving as a signal transducer or functional substrate for embedding nanoparticles/enzymes. Diabetes is one of the most common and fast-growing diseases worldwide, whose main clinical manifestation is high blood sugar levels. Therefore, accurate, sensitive, and point-of-care glucose detection is necessary. This review orderly introduces general synthetic strategies of MOF-based materials (pristine MOF, nanoparticles, or enzymes-modified MOF and MOF-derived materials) and detection methods (electrochemical and optical methods) for glucose detection. Then, the review refers to the novel MOF-based glucose detection devices (flexible wearable devices and microfluidic chips), which enable non-invasive continuous glucose monitoring or low-cost microscale detection. On the basis of describing the development of glucose sensors based on MOF materials in the past five years, the review presents merits, demerits, and possible improvements of various detection methods.
