“… 38 − 40 Nanotechnology advancements have enabled researchers to control the physicochemical characteristics of metallic nanomaterials to develop suitable nontoxic antimicrobial drugs, which shows high potentiality in the medicine field. 41 − 43 In the ongoing pandemic, antimicrobial metal NPs could be one of the effective solutions to address this issue. These NPs are active antibacterial agents due to their large active surface area which allows them to easily penetrate biofilms.…”

The ongoing worldwide pandemic due to COVID-19 has created awareness toward ensuring best practices to avoid the spread of microorganisms. In this regard, the research on creating a surface which destroys or inhibits the adherence of microbial/viral entities has gained renewed interest. Although many research reports are available on the antibacterial materials or coatings, there is a relatively small amount of data available on the use of antiviral materials. However, with more research geared toward this area, new information is being added to the literature every day. The combination of antibacterial and antiviral chemical entities represents a potentially path-breaking intervention to mitigate the spread of disease-causing agents. In this review, we have surveyed antibacterial and antiviral materials of various classes such as small-molecule organics, synthetic and biodegradable polymers, silver, TiO2, and copper-derived chemicals. The surface protection mechanisms of the materials against the pathogen colonies are discussed in detail, which highlights the key differences that could determine the parameters that would govern the future development of advanced antibacterial and antiviral materials and surfaces.

“…Morphologies of the porous materials are less homogeneous in terms of the diameter of fibers produced than in electrospinning. Both electrospinning and solution blow spinning allow obtaining variable morphologies, including corpuscles or beads, fibers or a combined mixture of corpuscles plus beads, depending on the viscosity of the solution and the processing conditions [ 91 , 135 , 136 , 137 , 138 ] that can condition the wettability behavior and particle adhesion such as cell adhesion [ 139 ].…”

Infections caused by bacteria are one of the main causes of mortality in hospitals all over the world. Bacteria can grow on many different surfaces and when this occurs, and bacteria colonize a surface, biofilms are formed. In this context, one of the main concerns is biofilm formation on medical devices such as urinary catheters, cardiac valves, pacemakers or prothesis. The development of bacteria also occurs on materials used for food packaging, wearable electronics or the textile industry. In all these applications polymeric materials are usually present. Research and development of polymer-based antibacterial materials is crucial to avoid the proliferation of bacteria. In this paper, we present a review about polymeric materials with antibacterial materials. The main strategies to produce materials with antibacterial properties are presented, for instance, the incorporation of inorganic particles, micro or nanostructuration of the surfaces and antifouling strategies are considered. The antibacterial mechanism exerted in each case is discussed. Methods of materials preparation are examined, presenting the main advantages or disadvantages of each one based on their potential uses. Finally, a review of the main characterization techniques and methods used to study polymer based antibacterial materials is carried out, including the use of single force cell spectroscopy, contact angle measurements and surface roughness to evaluate the role of the physicochemical properties and the micro or nanostructure in antibacterial behavior of the materials.

“…To reduce any potential risk of chemical leaching into food, antimicrobials of biological origin such as essential oils, natural phenolics (e.g., coumarin, gallic acid, resveratrol, quercetin, and tannic acid), natural cationic amines (e.g., lecithin from egg and soybean, chitosan from crustacean shells), and natural enzymes (e.g., lysozyme from egg and milk) have typically been utilized as active ingredients in these coatings (Benbettaïeb et al., 2020; Bruni et al., 2020; Busolo & Lagaron, 2015; Diaz‐Galindo et al., 2020; Fortunati et al., 2016; Glaser et al., 2019; Goudar et al., 2020; Halim et al., 2018; He, Fei, et al., 2020; Hosseini et al., 2019; Huang et al., 2020; Imran et al., 2012; Kwon et al., 2017; Lamarra et al., 2020; Li, Yan, et al., 2020; Liu et al., 2020; Lou et al., 2021; Luzi et al., 2019; Martinez‐Abad et al., 2012; Menezes et al., 2019; Milovanovic et al., 2018; Muriel‐Galet et al., 2014; Pan et al., 2019; Picchio et al., 2018; Tongdeesoontorn et al., 2020; Wang et al., 2019; Wen et al., 2016; Yadav et al., 2020, 2021; Zhan et al., 2020). Also, implementation of relatively low‐toxicity metals and their ions such as silver and copper in coatings for food contact surfaces has been commonly reported in the literature (Bahrami et al., 2019; Ferreira et al., 2019; Kim et al., 2019; Lee et al., 2019; Martinez‐Abad et al., 2012; Menezes et al., 2019).…”

“…Recently, a large amount of research has been conducted regarding the incorporation of silver ions and nanoparticles (NPs) as AMAs into coatings for food contact surfaces and food packaging materials (Bahrami et al., 2019; Bang et al., 2019; Ferreira et al., 2019; Kim et al., 2019; Lee et al., 2019; Lin et al., 2014; Martinez‐Abad et al., 2012; Menezes et al., 2019; Nthunya et al., 2017; Wang, Wang, et al., 2015; Zhan et al., 2020). Silver ions are naturally present in humans and typically found at blood levels below 2.3 µg/L (Wan et al., 1991).…”

Illness as the result of ingesting bacterially contaminated foodstuffs represents a significant annual loss of human quality of life and economic impact globally. Significant research investment has recently been made in developing new materials that can be used to construct food contacting tools and surfaces that might minimize the risk of cross‐contamination of bacteria from one food item to another. This is done to mitigate the spread of bacterial contamination and resultant foodborne illness. Internet‐based literature search tools such as Web of Science, Google Scholar, and Scopus were utilized to investigate publishing trends within the last 10 years related to the development of antimicrobial and antifouling surfaces with potential use in food processing applications. Technologies investigated were categorized into four major groups: antimicrobial agent–releasing coatings, contact‐based antimicrobial coatings, superhydrophobic antifouling coatings, and repulsion‐based antifouling coatings. The advantages for each group and technical challenges remaining before wide‐scale implementation were compared. A diverse array of emerging antimicrobial and antifouling technologies were identified, designed to suit a wide range of food contact applications. Although each poses distinct and promising advantages, significant further research investment will likely be required to reliably produce effective materials economically and safely enough to equip large‐scale operations such as farms, food processing facilities, and kitchens.
