“…Considering that glucose in the human body is mainly derived from food products and beverages, the evaluation of the glucose concentration in food products and beverages is significant to effectively control the intake of glucose and guarantee transparency regarding dietary risks. So far, a variety of analytical techniques for glucose detection have been established, such as colorimetric [ 7 , 8 ], electrochemical [ 9 , 10 ], chemiluminescence [ 11 , 12 ], mass spectrometry [ 13 , 14 ], fluorescence [ 15 , 16 ] and surface-enhanced Raman scattering [ 17 , 18 ] methods. Among these methods, as a rapid, specific and intuitive method, commercial glucose detection kits have been widely used, involving two consecutive enzyme reactions.…”

A one-step cobaltous chloride (CoCl2) molten salt method was employed to prepare multilayer MXene-Ti3C2/Co materials with further ultrasonic treatment to acquire single-layer MXene-Ti3C2/Co nanosheets (NSs). MXene-Ti3C2/Co NSs were characterized, and their enzyme-like activities were investigated. Under the catalysis of MXene-Ti3C2/Co NSs, 3,3′,5,5′-tetramethylbenzidine (TMB) could be oxidized by H2O2, with the color changing from colorless to blue. The affinity of MXene-Ti3C2/Co NSs to H2O2 and TMB was better than that of nanozymes reported in previous studies. The MXene-Ti3C2/Co NSs were used for the colorimetric determination of H2O2/glucose, with limits of detection (LODs) of 0.033 mM and 1.7 μM, respectively. MXene-Ti3C2/Co NSs embedded in sodium alginate (SA) hydrogel were used to construct a sensor platform. The digital pictures combined with a smartphone-installed app (color recognizer) could be used to analyze RGB values for colorimetric detection of glucose in beverages. This point-of-care testing platform has the advantages of cost-effectiveness and good transferability, with the potential to realize quick, intelligent and on-site detection.
