THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 954:176697. [PMID: 39366577 DOI: 10.1016/j.scitotenv.2024.176697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2024] [Revised: 09/13/2024] [Accepted: 10/01/2024] [Indexed: 10/06/2024]
Abstract
This study investigates the integration of Ti3C2Tx (MX) and Ag/Ti3C2Tx (Ag/MX) nanocomposites into polylactic acid membranes to enhance hydrophilicity and impart antibacterial properties, targeting hospital wastewater treatment. MX and silver nanoparticles are known for their hydrophilicity and antimicrobial capabilities, were synthesized and incorporated into PLA; a green polymer. The impact of nanocomposite concentration on the membrane's chemical structure, morphology, and overall performance were characterized using various PLA membrane properties and to evaluate the nanocomposite's performance in enhancing pure water flux and antibacterial efficacy. The pure water permeability increased from 1512 L m-2 h-1 bar-1 to 3108 L m-2 h-1 bar-1 in PLA/AgMX4 compared to PLA. Furthermore, a total bacteria count (TBC) rejection of up to 97 % was obtained using the PLA/AgMX4 membrane. The results demonstrated significant improvements in PLA/AgMX membranes compared to pristine PLA, showing a large potential for hospital wastewater treatment.

Abstract
The integration of two-dimensional Ti3C2Tx nanosheets and other materials offers broader application options in the antibacterial field. Ti3C2Tx-based composites demonstrate synergistic physical, chemical, and photodynamic antibacterial activity. In this review, we aim to explore the potential of Ti3C2Tx-based composites in the fabrication of an antibiotic-free antibacterial agent with a focus on their systematic classification, manufacturing technology, and application potential. We investigate various components of Ti3C2Tx-based composites, such as metals, metal oxides, metal sulfides, organic frameworks, photosensitizers, etc. We also summarize the fabrication techniques used for preparing Ti3C2Tx-based composites, including solution mixing, chemical synthesis, layer-by-layer self-assembly, electrostatic assembly, and three-dimensional (3D) printing. The most recent developments in antibacterial application are also thoroughly discussed, with special attention to the medical, water treatment, food preservation, flexible textile, and industrial sectors. Ultimately, the future directions and opportunities are delineated, underscoring the focus of further research, such as elucidating microscopic mechanisms, achieving a balance between biocompatibility and antibacterial efficiency, and investigating effective, eco-friendly synthesis techniques combined with intelligent technology. A survey of the literature provides a comprehensive overview of the state-of-the-art developments in Ti3C2Tx-based composites and their potential applications in various fields. This comprehensive review covers the variety, preparation methods, and applications of Ti3C2Tx-based composites, drawing upon a total of 171 English-language references. Notably, 155 of these references are from the past five years, indicating significant recent progress and interest in this research area.

Fang Z, Zhou Q, Zhang W, Wang J, Liu Y, Yu M, Qiu Y, Ma Z, Liu S. A Synergistic Antibacterial Study of Copper-Doped Polydopamine on Ti 3C 2T x Nanosheets with Enhanced Photothermal and Fenton-like Activities. MATERIALS (BASEL, SWITZERLAND) 2023; 16:7583. [PMID: 38138725 PMCID: PMC10744557 DOI: 10.3390/ma16247583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 11/22/2023] [Accepted: 12/08/2023] [Indexed: 12/24/2023]
Abstract
In response to the trend of drug-resistant and super bacteria, the existing single antibacterial methods are not sufficient to kill bacteria, and the development of multifunctional antibacterial nanomaterials is urgent. Our study aims to construct copper-doped polydopamine-coated Ti3C2Tx (CuPDA@Ti3C2Tx) with an enhanced photothermal property and Fenton-like activity. The nanocomposite hydrogel consisting of CuPDA@Ti3C2Tx and alginate can improve the antioxidant activity of two-dimensional MXene nanosheets by coating them with a thin layer of PDA nanofilm. Meanwhile, Cu ions are adsorbed through the coordination of PDA-rich oxygen-containing functional groups and amino groups. Calcium ions were further used to crosslink sodium alginate to obtain antibacterial hydrogel materials with combined chemotherapy and photothermal therapy properties. The photothermal conversion efficiency of CuPDA@Ti3C2Tx is as high as 57.7% and the antibacterial rate of Escherichia coli reaches 96.12%. The photothermal effect leads to oxidative stress in bacteria, increases cell membrane permeability, and a high amount of ROS and copper ions enter the interior of the bacteria, causing protein denaturation and DNA damage, synergistically leading to bacterial death. Our study involves a multifunctional synergistic antibacterial nanodrug platform, which is conducive to the development of high-performance antibacterial agents and provides important research ideas for solving the problem of drug-resistant bacteria.
