Metal–Organic-Framework- and MXene-Based Taste Sensors and Glucose Detection

Abstract

Taste sensors can identify various tastes, including saltiness, bitterness, sweetness, sourness, and umami, and have been useful in the food and beverage industry. Metal–organic frameworks (MOFs) and MXenes have recently received considerable attention for the fabrication of high-performance biosensors owing to their large surface area, high ion transfer ability, adjustable chemical structure. Notably, MOFs with large surface areas, tunable chemical structures, and high stability have been explored in various applications, whereas MXenes with good conductivity, excellent ion-transport characteristics, and ease of modification have exhibited great potential in biochemical sensing. This review first outlines the importance of taste sensors, their operation mechanism, and measuring methods in sensing utilization. Then, recent studies focusing on MOFs and MXenes for the detection of different tastes are discussed. Finally, future directions for biomimetic tongues based on MOFs and MXenes are discussed.

Metal-Organic Frameworks Based Multifunctional Materials for Solar Cells: A Review

“…For instance, HKUST-1 was constructed by symmetry units, including a copper paddle wheel (-Cu2(COO)4) along with benzene-1,3,5tricarboxylic acid (H3BTC). MOFs have a crystal, porous framework structure, making them promising candidates in various applications such as gas adsorption, catalysis, and sensors [38][39][40][41][42][43]. In particular, MOFs containing unsaturated metal sites and Lewis basis sites were evaluated as promising materials for gas storage, such as CH4, CO2, and H2 [44].…”

MOF-Based Materials for Glucose Detection

“…Nowadays, the self-monitoring of blood glucose levels is the most efficient way for the management of diabetes and other related disease [5]. Except for the above-mentioned applications, glucose detection is also applied in artificial taste sensors and quality control of food and drinks [6].…”
