Preparation of 2D Polyaniline/MoO3−x Superlattice Nanosheets via Intercalation‐Induced Morphological Transformation for Efficient Chemodynamic Therapy

Abstract: Organic intercalation of layered nanomaterials is an attractive strategy to fabricate organic/inorganic superlattices for a wide range of promising applications. However, the synthesis of 2D organic/inorganic superlattice nanosheets remains a big challenge. Herein, the preparation of 2D polyaniline/MoO3−x (PANI/MoO3−x) superlattice nanosheets via intercalation‐induced morphological transformation from MoO3 nanobelts, as efficient Fenton‐like reagents for chemodynamic therapy (CDT), is reported. Micrometer‐long… Show more

“…For example, modulating the TME states, such as lowing the pH of the tumor [22], designing Fenton reaction reagents that are less dependent on pH [23,24], increasing the level of H2O2 [17,25,26], or consuming GSH in the tumor [27,28], can improve the therapeutic outcome of CDT. Besides, optimizing the morphology and interface properties of the catalysts could enhance their catalytic ability, since the chemical composition, size, and aggregation of the nanocatalysts have a great impact on the catalytic rate and activity of the Fenton reaction [29]. Nowadays, a variety of nanocatalysts (transition metal nanomaterials, metal-organic nanomaterials, monoatomic nanomaterials, and electron-rich nanomaterials) are synthesized to improve CDT efficiency [30][31][32][33].…”

“…In order to illustrate the enhancement of gas-sensitive properties by doping MoO 3 nanowires and Cu nanoparticles, a sensitivity mechanism based on the synergistic enhancement effect of the p−n junction and Schottky junction is proposed. 25,27,30 Specifically, as shown in Figure 9b, during the sensing process, NH 3 combines with acid-doped PANI, resulting in the transformation of PANI from an emerald salt with high conductivity to an emerald base with low conductivity. In this case, the internal electronic balance of the composite material is broken, and in order to reach the new Fermi level equilibrium state, the p−n junction depletion layer formed by the PANI-MoO 3 interface is widened (PANI side), resulting in a narrowing of the conductive path.…”

“…Numerous cutting-edge substances, including nano-metal oxides ( Ning et al, 2017 ; Jin et al, 2019 ; He et al, 2022a ), two-dimensional (2D) materials ( Liu et al, 2016 ; Zhao et al, 2023 ), and other photosensitive substances ( Liu et al, 2019 ), can produce electron-hole pairs when exposed to certain wavelengths of light. The ejected electrons can then be captured by the oxygen in the environment to create reactive oxygen species (ROS), which can cause the death of pathogenic or diseased cells ( Chen et al, 2022a ; Zhou et al, 2022b ; Hu et al, 2023 ). In particular, versus traditional chemotherapy, photodynamic therapy (PDT) manages to avoid the progression of drug resistance by primarily acting its biocidal activity through the oxidative damage of biological macromolecules such as lecithin, enzymes, nutrients, and DNA in cell membranes ( Zhang et al, 2022b ; Xiu et al, 2022 ).…”
