“…Some of these strategies that are being presently adopted to treat SSIs associated with biofilm formation are: inhibiting the attachment of the microorganisms to the substratum, using special compounds that interfere with and unsettle the biofilm structure, and disrupting the biofilm at the initial stages [ 22 , 23 ]. For example, to help control the rate of SSIs, new antiadhesive surfaces with altered physical, chemical, and topographical properties that prevent microbial adhesion and thereby biofilm formation have been tested on several medical devices [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ].…”

“…Several antimicrobial compounds have been identified as potential biofilm eradicators, namely antimicrobial peptides (AMPs), EPS-targeting enzymes, antimicrobial lipids, quaternary ammonium compounds (QACs), nitric-oxide-releasing antibiotics, and others [ 8 ]. Nanotechnology-based approaches, predominantly different types of NPs, metal organic frameworks (MOFs), and other nanomaterials, are also amongst the most studied line of attack to deal with pathogenic biofilms [ 22 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 35 , 36 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ]. Natural plant-based products are being developed to help overcome the problem with multidrug-resistant bacteria, namely plant extracts and isolated compounds, as well as essential oils that contain large amounts of phytochemicals [ 33 , 34 , 37 , 38 , 39 , 40 , 41 , 42 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ].…”

“…In this approach, the NPs contained a superparamagnetic iron oxide core, allowing for targeted accumulation of NPs at the infection site, whereas the nanoporous silica shell could be useful to carry large amounts of the drug [ 51 ]. Kurniawan et al [ 32 ] presented a solution for a common issue that is usually encountered in many hospital facilities, contaminated bed sheets, as well as other medical devices that are listed as potential sources of infection. This research group had the idea of using a multiple-layer technique of coating NPs with zinc oxide (ZnO-NPs), resulting in increased hydrophobicity of the bed sheets and good antibacterial activity against both Gram-positive and Gram-negative bacteria.…”

“…These ZnO-NPs have the particularity of promoting ROS generation and Zn 2+ ions’ release, which reduce the activity of Zn 2+ -dependent enzymes and transcription factors and/or cause lysosomal destabilization in the bacterial cells, leading to their death. Moreover, ZnO-NPs promote the production of H 2 O 2 under ultraviolet light irradiation, which is severely toxic to living cells [ 32 ]. Kapustová et al [ 52 ] developed eco-friendly nanosystems of encapsulated Thymus capitatus and Origanum vulgare essential oils in biocompatible PCL nanocapsules.…”

Biofilms in Surgical Site Infections: Recent Advances and Novel Prevention and Eradication Strategies

Surgical site infections (SSIs) are common postoperative occurrences due to contamination of the surgical wound or implanted medical devices with community or hospital-acquired microorganisms, as well as other endogenous opportunistic microbes. Despite numerous rules and guidelines applied to prevent these infections, SSI rates are considerably high, constituting a threat to the healthcare system in terms of morbidity, prolonged hospitalization, and death. Approximately 80% of human SSIs, including chronic wound infections, are related to biofilm-forming bacteria. Biofilm-associated SSIs are extremely difficult to treat with conventional antibiotics due to several tolerance mechanisms provided by the multidrug-resistant bacteria, usually arranged as polymicrobial communities. In this review, novel strategies to control, i.e., prevent and eradicate, biofilms in SSIs are presented and discussed, focusing mainly on two attractive approaches: the use of nanotechnology-based composites and natural plant-based products. An overview of new therapeutic agents and strategic approaches to control epidemic multidrug-resistant pathogenic microorganisms, particularly when biofilms are present, is provided alongside other combinatorial approaches as attempts to obtain synergistic effects with conventional antibiotics and restore their efficacy to treat biofilm-mediated SSIs. Some detection and real-time monitoring systems to improve biofilm control strategies and diagnosis of human infections are also discussed.

“…Regardless of the morphology, the ZnO-NPs have shown a high light absorption capability and excellent inhibition to many Gram-positive and Gram-negative bacteria. Furthermore, a large-scale process to coat the hydrophobic and antibacterial bed sheet with ZnO has been proposed using a rolling-dipping machine [ 99 ].…”

Rapid transmission of infectious microorganisms such as viruses and bacteria through person-to-person contact has contributed significantly to global health issues. The high survivability of these microorganisms on the material surface enumerates their transmissibility to the susceptible patient. The antimicrobial coating has emerged as one of the most interesting technologies to prevent growth and subsequently kill disease-causing microorganisms. It offers an effective solution a non-invasive, low-cost, easy-in-use, side-effect-free, and environmentally friendly method to prevent nosocomial infection. Among antimicrobial coating, zinc oxide (ZnO) stands as one of the excellent materials owing to zero toxicity, high biocompatibility to human organs, good stability, high abundancy, affordability, and high photocatalytic performance to kill various infectious pathogens. Therefore, this review provides the latest research progress on advanced applications of ZnO nanostructure-based antibacterial coatings for medical devices, biomedical applications, and health care facilities. Finally, future challenges and clinical practices of ZnO-based antibacterial coating are addressed.

Robust, Conformal ZnO Coatings on Fabrics via Atmospheric‐Pressure Spatial Atomic Layer Deposition with In‐Situ Thickness Control**

et al. 2023

Zinc oxide (ZnO) is a promising material for functionalization of textiles. It can add a range of functionalities, including UV protection, antimicrobial activity, flame retardancy, hydrophobicity and electrical conductivity. Commercialization of ZnO -coated textiles is still limited due to the cost and challenges related to their manufacture. Moreover, making robust coatings on textiles and measuring their thickness is also challenging. In this work, atmosphericpressure spatial atomic layer deposition (AP-SALD) systems are utilized for the first time to coat synthetic spun-bond polypropylene (PP) and natural cotton fabrics with ZnO. The coatings are found to be conformal and uniform, forming complete shells around the fabric fibers. The growth rate is measured to be ~0.24 nm/cycle using an in-situ reflectance setup and Virtual Interface (VI) model, which enable precise control of the coating thickness. The coatings are shown to provide UV-protection and render cotton fabric hydrophobic. No damage is observed after washing, linear abrasion, adhesion, twisting and bending tests, indicating that the coatings are robust. Aerosol-penetration tests indicate the coatings do not impact the filtering efficiency of fabrics used in N95 respirators. The results are encouraging for industrialization of the AP-SALD technique for functional textiles.
