“…The absorption peaks in the wavelength ranging from 500–3000 correspond to the characteristic peaks of Co‐MOF (756, 1140, 1300, 1420, 1780, 2160, 2926, and 2955). [ 52 ] The characteristic peaks of CoPi are 977 and 1035 cm −1 . [ 53 ] These data strongly confirm the successful preparation of PtNFs/CoPi composites on the CC surface.…”

Malignant tumors pose a serious risk to human health. Ascorbic acid (AA) has potential for tumor therapy; however, the mechanism underlying the ability of AA to selectively kill tumor cells remains unclear. AA can cause redox disequilibrium in tumor cells, resulting in the release of abundant reactive oxygen species, represented by hydrogen peroxide (H2O2). Therefore, the detection of H2O2 changes can provide insight into the selective killing mechanism of AA against tumor cells. In this work, inspired by the ion‐exchange mechanism in coral formation, a flexible H2O2 sensor (PtNFs/CoPi@CC) is constructed to monitor the dynamics of H2O2 in the cell microenvironment, which exhibits excellent sensitivity and spatiotemporal resolution. Moreover, the findings suggest that dehydroascorbic acid (DHA), the oxidation product of AA, is highly possible the substance that actually acts on tumor cells in AA therapy. Additionally, the intracellular redox disequilibrium and H2O2 release caused by DHA are positively correlated with the abundance and activity of glucose transporter 1 (GLUT1). In conclusion, this work has revealed the potential mechanism underlying the ability of AA to selectively kill tumor cells through the construction and use of PtNFs/CoPi@CC. The findings provide new insights into the clinical application of AA.

Aristolochic acid I is a toxic compound found in the genus of Aristolochia plants, which are commonly used as herbal cough treatment medicines. To remove the aristolochic acid I in extract efficiently and selectively, a molecularly imprinted polymer composed of ethylimidazole ionic liquid‐based zeolitic imidazolate framework‐67 was synthesized and used as the adsorbent. Under the conditions optimized by the software design expert, the sorbent showed highest adsorption amount of 34.25 mg/g in methanol/water (95:5, v/v) at 39°C for 138 min. The sorbent was then applied to solid phase extraction to isolate aristolochic acid I from the extract of the herbal plant Fibraurea Recisa Pierre. 0.043 mg/g of aristolochic acid I was obtained after the loading, washing, and elution processes. The limit of detection of 2.41 × 10−5 mg/mL and good recoveries provided evidence for the accuracy of this method.

“…Magnetic CNT@MOF nanocomposites have also been used for pollutant removal from aqueous solutions. [71][72][73][74][75] These composites can be easily separated from aqueous media after the pollutant removal process by using an external magnetic field.

Metal–organic frameworks (MOFs) materials constructed by the coordination chemistry of metal ions and organic ligands are important members of the crystalline materials family. Owing to their exceptional properties, for example, high porosity, tunable pore size, and large surface area, MOFs have been applied in several fields such as gas or liquid adsorbents, sensors, batteries, and supercapacitors. However, poor conductivity and low stability hamper their potential applications in several attractive fields such as energy and gas storage. The integration of MOFs with carbon nanotubes (CNTs), a well‐established carbon allotrope that exhibits high conductivity and stability, has been proposed as an efficient strategy to overcome such limitations. By combining the advantages of MOFs and CNTs, a wide variety of composites can be prepared with properties superior to their parent materials. This review provides a comprehensive summary of the preparation of CNT@MOF composites and focuses on their recent applications in several important fields, such as water purification, gas storage and separation, sensing, electrocatalysis, and energy storage (supercapacitors and batteries). Future challenges and prospects for CNT@MOF composites are also discussed.
