Activities of gallic acid and Fe doped, and glucose oxidase or gold modified ZIF-8 based drug delivery systems in triple negative breast cancer

Modulation of the enzyme-like activity of CuAsp nanozyme by gallic acid and the selective detection of bisphenol A in infant food packaging

“…The out-of-plane bending of the phenolic hydroxyl group to a characteristic peak at 760 cm −1 , and the non-C-H planar bending of the gallic acid benzene ring correspond to the 863 cm −1 characteristic peaks. 35 These results conrm the successful modication of CuAsp by GA.…”

“…33 GA-CuAsp nanozyme was synthesized with reference to previous literature and optimized accordingly. 34,35 CuAsp solution (12 mL) , which was not washed with ethanol : water (1 : 1, v/v), was mixed with GA solution (5 mmol L −1 , 12 mL), and the mixed solution was stirred at room temperature for 4 h. Then the solution was centrifuged (10 000 rpm, 3 min) to obtain a blue precipitate, which was washed three times with ethanol : water (1 : 1, v/v) solution. Finally, the obtained GA-CuAsp nanozyme was dissolved into deionized water and kept in a refrigerator at 4 °C.…”

The Application of Bilayer Heterogeneous MOFs in pH and Heat-Triggered Systems for Controllable Fragrance Release

“…In addition, ZIF-8 has excellent acid responsiveness and can be stabilized in physiological aqueous environments, while the zeolite imidazolium ester skeleton collapses when the pH is weakly acidic (pH 5–6), which facilitates the control of the release of the functional materials by adjusting the pH [ 15 ]. On the basis of the above characteristics, ZIF-8 is widely used in the biomedical field to encapsulate various functional materials, such as 5-fluorouracil [ 16 ], gentiopicroside [ 17 ], riboflavin-5-phosphate [ 18 ], 6-mercaptopurine [ 19 ], and metformin [ 20 ]. On the basis of these advantages of ZIFs and aiming to further increase fragrance loading and achieve controlled release, a series of ZIF-8 materials with single-layer and double-layer core–shell structures were synthesized as carriers for encapsulating vanillin using a simple room temperature solvent method.…”
