“…In fact, Puvvada et al. proposed that ZnO coating at low ALD treatment has little antibacterial activity, [ 29 ] but the antibacterial effect of ALD modification on cotton fabric pretreated with PDA was significantly improved. In addition, ZnO coated cotton fabrics @ PDA treated with 10 ALD cycles have inhibitory effects on both E. coli and S. aureus , but there are differences in the mechanism of action.…”

“…[ 22 ] Due to its strong binding force, almost no waste of raw materials and environmental pollution, ALD has potential application value in textile modification, such as conductive treating, [ 23 ] hydrophobic finishing, [ 24 ] heat insulating, [ 25,26 ] and UV protecting. [ 27 ] Previous studies have applied ALD in antibacterial modification of textiles, [ 28–30 ] but all of those reports pointed out that the antibacterial textiles were obtained after more than 100 ALD cycles and 120 °C reaction temperature. Herein, taking advantage of the good adhesion between the polymer produced by dopamine in aqueous solution and the substrate, [ 31 ] the cotton fabric was treated with dopamine, and then the strategy based on the controllability and stability of ALD was introduced to form a layer of ZnO film on the surface of cotton fabric, the fast deposition process of 1 min per cycle was realized by the precisely regulated ALD equipment, and it has proven that PDA can achieve high antibacterial properties on cotton textiles by coupling with just 10 ALD cycles ZnO.…”

The urgent need of healthcare promotes the research and development of antibacterial textiles. However, conventional antibacterial textile is based on the solution method to form bacteriostatic granules on the textile matrix, and this form of textile has lurking perils to environment and low durability. Herein, a distinctive self‐limiting surface chemical reaction, atomic layer deposition (ALD), is proposed that deposit zinc oxide (ZnO) on cotton fabrics pretreated with polydopamine (PDA) to prepare nanocomposite textiles in an exceedingly short time by meticulously regulating the parameters. The results show that the cotton @ PDA treated for only 10 min has more than 95% antibacterial rate against both S. aureus and E. coli, which is better than that treated by ALD or PDA alone. Besides, the significance of reactive oxygen species in the antibacterial activity of PDA and ZnO composite coating is confirmed by introducing vitamin E for the first time. Thanks to PDA pre coating and the unique interface combination mode of ALD, the antibacterial textiles introduced in this study have excellent durability. The strategy proposed in this paper can provide a theoretical basis for the antibacterial modification of medical devices.

“…Curiously enough, at low ZnO loading, bacteria could metabolize Zn 2+ ions and reproduced more rapidly. However, they found that increasing the thickness of the ZnO film, the nanocoating became an effective biocide material with a complete eradication of all E. coli bacteria present [ 37 ].…”

Recent Advances on Antimicrobial and Anti-Inflammatory Cotton Fabrics Containing Nanostructures

Hydrophilic cotton textiles, used in hospitals and sportswear, are prone to the growth of microorganisms (bacteria, fungi) resulting in hygiene and health risks. Thus, healthcare concerns have motivated the interest for the development of multifunctional antimicrobial cotton fabrics. Moreover, cotton textiles are also used in medical applications such as wound dressings. Their functionalization with anti-inflammatory agents is desirable in order to accelerate cicatrisation in the treatment of chronic wounds. This review summarizes recent advances (from January 2016 to January 2021) on the modification and coating of cotton fabrics with nanostructures (mainly metal and metal oxide nanoparticles, functionalized silica nanoparticles) to provide them antimicrobial (antibacterial and antifungal) and anti-inflammatory properties.

“…Coatings of titanium dioxide and copper/zinc oxides , have been fabricated using vapor deposition techniques to harness their inherent antibacterial nature (see below for details on their antibacterial mechanisms). Metal oxides have also been employed as a physical material enhancement (e.g., transparency) for copper-oxide-based antimicrobial coatings …”

At the biointerface where materials and microorganisms meet, the organic and synthetic worlds merge into a new science that directs the design and safe use of synthetic materials for biological applications. Vapor deposition techniques provide an effective way to control the material properties of these biointerfaces with molecular-level precision that is important for biomaterials to interface with bacteria. In recent years, biointerface research that focuses on bacteria–surface interactions has been primarily driven by the goals of killing bacteria (antimicrobial) and fouling prevention (antifouling). Nevertheless, vapor deposition techniques have the potential to create biointerfaces with features that can manipulate and dictate the behavior of bacteria rather than killing or deterring them. In this review, we focus on recent advances in antimicrobial and antifouling biointerfaces produced through vapor deposition and provide an outlook on opportunities to capitalize on the features of these techniques to find unexplored connections between surface features and microbial behavior.
