“…These kind of sensors have the conspicuous advantages of ingenious sensitivity, superior reproducibility, and low price. , Although traditional nonenzymatic glucose sensors based on noble metals and their alloys have displayed outstanding glucose electrooxidation capability, the relatively high price and low yield of these electrode catalysts still limit their significant progress. Therefore, many TM-based materials as electrode materials for nonenzymatic electrochemical glucose sensing have been widely developed in recent years. , …”

We exploited a tactic to obtain a low-cost, highefficiency, pollution-free, and stable nonenzymatic polyoxometalatebased heterogeneous electrode material for electrochemical sensing of glucose. It is first followed by the countercation exchange of K 2 Na 8 [Cu 4 (H 2 O) 2 (PW 9 O 34 ) 2 ] (CuPOM) using cesium chloride to prepare an insoluble CuPOM (Cs-CuPOM), which exhibits a uniform and perfect claviform shape with smooth surface. Further, it was mixed with graphite powder to prepare Cs-CuPOM-modified carbon paste electrode (Cs-CuPOM/CPE) with the Cs-CuPOM content between 15% and 50% in weight. This obtained electrode material Cs-CuPOM shows a better electrochemical sensor activity than Cs-MnPOM, Cs-FePOM, and other reported POM-based electrode materials for glucose oxidation on account of their quicker electron transfer kinetics, which also exhibits conspicuous characteristics with a wide linear range of 5−1500 μM. It also possesses a high sensitivity of 16.3 A M −1 cm −2 and a low limit of detection (LOD) of 0.99 × 10 −6 M at the signal-to-noise ratio of 3. The conspicuous sensing feature, low cost, and liable synthetic method can make Cs-CuPOM a promising candidate for the exploitation of a preeminent glucose sensor.

Comprehensive SummaryAs one of the famous traditional Chinese herbal medicines, Fritillariae Cirrhosae Bulbus (FCB) is widely used in the prevention and treatment of respiratory diseases and has the best curative effect among the known fritillarias medicines. Due to the variety, complex sources, similar appearance and shape, it is difficult to distinguish FCB with high curative effect (h‐FCB) from other common fritillarias (c‐FCB) in the market. In this paper, a very simple chemiresistor is used to identify FCB from three commonly used fritillarias drugs. The sensors are fabricated by anisotropic electrically conductive metal‐organic framework (cMOF) thin film Cu3(HHTP)2 (Cu‐HHTP[001] and Cu‐HHTP[100]) as active materials owing to their ability to detect specific groups of volatile organic compounds (volatolomics) as the functional motifs of chemiresistor. As a result, the sensors show orientation‐dependence identification ability to FCB. Cu‐HHTP[001]‐ based sensor shows the highest response (344.17%) to 0.5 g h‐FCB powder volatiles among its three other c‐FCB which is much higher than Cu‐HHTP[100] (135.50%). Ultimately, Cu‐HHTP[001] can realize the identification of FCB with an accuracy of 97.2% in a simple and real‐time manner.
