MoS₂/PDA@Cu composite as a peroxidase-mimicking enzyme with high-effect antibacterial and anticancer activity

Abstract

Since nanozymes were proposed, their applications have become more and more extensive. As a research hotspot in recent years, MoS2 also shows many enzyme-like properties. However, as a novel peroxidase,...

Unveiling the antibacterial strategies and mechanisms of MoS2: a comprehensive analysis and future directions

“…Based on the aforementioned content, we have designed a novel MoS 2 /PDA@Cu nanozyme, 162 as depicted in Fig. 12.…”

Recent advances in nanomaterial-mediated bacterial molecular action and their applications in wound therapy

“…At present, highly active antibacterial nanomaterials have attracted growing interest as antibacterial agents, including carbon-based nanomaterials, 35-44 noble metal nanomaterials, [45][46][47][48][49][50][51] metal oxide nanomaterials, [52][53][54][55][56][57] transition metal sulfides, [58][59][60] metal-organic frameworks (MOFs) 61,62 as well as composite nanomaterials (Table 1). [63][64][65][66][67][68] The currently studied antibacterial mechanisms mainly involve the following aspects: physical penetration, physical wrapping, photothermal ablation, and oxidative stress (Fig.…”

“…Liu et al indicated that the PDA molecule, metal Cu NPs, and Cu 2+ could promote the catalytic reaction of MoS 2 /PDA@Cu nanozyme, and exhibit good inhibition against S. aureus when the concentration was 25 μg mL −1 . 59 In addition, evidence has emerged that H 2 O 2 or O 2 could be adsorbed on the metal surface. It could accomplish the enzymatic activity by decomposition and producing ROS for antibacterial action.…”

Photodynamically Functionalized CoP/MoS2 Nanocomposites with Antibacterial Activity

“…5 Some semi-conductor photocatalysts, such as metal oxides, metal sulfides, carbon-based materials, etc., 6 exhibit high inherent peroxidaselike activity and can efficiently catalyze low-concentration H 2 O 2 to active • OH, which shows higher antibacterial activity than H 2 O 2 . 7 Taken together, the special antibacterial mechanism of semiconductor photocatalyst prevents the development of drug resistance and presents fewer side effects of the photocatalytic inactivation technique.…”
