“…In turn, about 38% of studies produced films by dip coating method, which was effective in reducing both microbial adhesion and biofilm formation (20%–100%) ( Bulwan et al., 2012 ; Cobrado et al, 2013 ; Cao and Sun, 2009 ; Kara et al, 2014 ; Martinez et al., 2010b ; Mendoza et al., 2018 ; Niemczyk et al, 2019 ; Rubini et al, 2021 ; Silva-Dias et al, 2014 ; Valverde et al, 2019 ; Wang et al., 2012a , 2012b ; Yang et al., 2019 ; Yuan et al., 2013 ; Zhang et al., 2018 ). Dip coating is a simple approach to coat a substrate generating uniform and thin films ( Scriven, 2011 ).…”

Antimicrobial coatings based on chitosan to prevent implant-associated infections: A systematic review

et al. 2021

View full text Add to dashboard Cite

Summary Despite the advancements in material science and surgical techniques, the incidence of implant-associated infections (IAIs) has increased significantly. IAIs are mainly caused by microbial adhesion and biofilm formation on implant surfaces. In this study, we aimed to evaluate and critically discuss the antimicrobial efficacy of chitosan-based coatings to prevent the occurrence of IAIs. For this purpose, a PRISMA-oriented systematic review was conducted based on predefined criteria and forty studies were selected for qualitative analysis. Results indicated that chitosan (CS) association with enzymes and antimicrobial peptides improves its antimicrobial activity and extends its use in a broad range of physiological conditions. Likewise, CS association with polymers resulted in enhanced antimicrobial and anti-adhesive coatings with desirable properties, such as biocompatibility and durability, for implantable medical devices (IMDs). These findings can assist researchers in the design of new CS coatings for application in IMDs.

“…Previous studies demonstrated that the interaction with the EOs, mainly terpenes, caused an alteration of cell surface hydrophobicity [20]. Rubini et al (2021) [39] aimed to obtain materials with an enhanced hydrophilic surface to prevent biofilms formation. This desideratum could be achieved by incorporating an EO into various materials to ensure a controlled release in a lower than cytotoxic concentration for modulating the hydrophobicity of the microbial cell surface and decreas-ing its adherence and biofilm development ability.…”

The purpose of this paper was to characterize and investigate the antimicrobial potential of Amorpha fruticosa fruits essential oil (EO). The EO was extracted by hydrodistillation, analyzed by GC-MS, and then evaluated for its interaction with microbial and mammalian cells. The antimicrobial activity was assessed against bacterial and fungal strains, in a planktonic and adherent growth state, using qualitative and quantitative assays. The main components identified in A. fruticosa fruits EO were δ-cadinene, γ-muurolene, and α-muurolene. The Gram-positive strains proved to be more susceptible than Gram-negative bacteria and fungal strains. The EO exhibited good antibiofilm activity, inhibiting the microbial adherence to the inert (96-well plates and Foley catheter section) and cellular substrata. The flow cytometry analysis revealed as one of the possible mechanisms of antimicrobial action the alteration of cell membrane hydrophobicity. The cytotoxicity on the L929 cell line occurred at concentrations higher than 0.3 mg/mL. Taken together, our results demonstrate that A. fruticosa fruits EO contains active compounds with selective inhibitory effect on different microbial strains in planktonic and biofilm growth state, explained at least partially by the interference with microbial membranes due to their hydrophobic character.

This review article explores the recent innovations in the field of antimicrobial and antiviral macromolecules. With the rising challenge of antibiotic resistance, as well as the overuse of antibiotics, there is a growing demand for efficient solutions to combat microbial and viral infections. The development of new effective antimicrobial and antiviral agents is highlighted. This review was designed to give a comprehensive view of the literature focusing on a few examples of combating microbial and viral infections in each section. A brief description of naturally occurring organic‐based materials that exhibited antimicrobial and/or antiviral activities is presented, focusing on polysaccharides, peptides and proteins. Synthetic organic‐based materials are divided into subsections including polymers, dendrimers, and nanomaterials. The synthesis and applications of inorganic materials such as polyphosphazenes and polysiloxanes, as well as tin‐, germanium‐ and gallium‐based materials are emphasized in this review. Organometallic macromolecules are also described, and their antimicrobial and antiviral activities are examined. Overall, this article provides a comprehensive overview of recent advancements in the design of antimicrobial and antiviral macromolecules, offering valuable insights into their potential applications in biomedical research and combating drug‐resistant microorganisms and viruses.This article is protected by copyright.
