“…These results corroborate the biofilm culturable cell analysis and are in accordance with previous studies where the effect of CS-based paints on biofilm structure was evaluated. El-Saied et al [ 71 ] investigated the antifouling performance of a CS-based marine paint by immersing coated PVC panels in the Mediterranean Sea Eastern Harbor of Alexandria. The findings revealed the long-term antifouling activity of CS since the coatings inhibited the development of tubeworms and barnacles on panels submerged for more than two months.…”

Marine biofouling is a natural process often associated with biofilm formation on submerged surfaces, creating a massive economic and ecological burden. Although several antifouling paints have been used to prevent biofouling, growing ecological concerns emphasize the need to develop new and environmentally friendly antifouling approaches such as bio-based coatings. Chitosan (CS) is a natural polymer that has been widely used due to its outstanding biological properties, including non-toxicity and antimicrobial activity. This work aims to produce and characterize poly (lactic acid) (PLA)-CS surfaces with CS of different molecular weight (Mw) at different concentrations for application in marine paints. Loligo opalescens pens, a waste from the fishery industry, were used as a CS source. The antimicrobial activity of the CS and CS-functionalized surfaces was assessed against Cobetia marina, a model proteobacterium for marine biofouling. Results demonstrate that CS targets the bacterial cell membrane, and PLA-CS surfaces were able to reduce the number of culturable cells up to 68% compared to control, with this activity dependent on CS Mw. The antifouling performance was corroborated by Optical Coherence Tomography since PLA-CS surfaces reduced the biofilm thickness by up to 36%, as well as the percentage and size of biofilm empty spaces. Overall, CS coatings showed to be a promising approach to reducing biofouling in marine environments mimicked in this work, contributing to the valorization of fishing waste and encouraging further research on this topic.

“…Therefore, Türkeş & Açıkel (2020) prepared pure halloysite nanotubes and chitosan nanocomposites (MHNT-CTN) for the adsorption of methylene blue via the co-precipitation technique by developing suitable magnetic properties of MHNT-CTN. In another study, the immersion of chitosan-capped ZnO nanoparticles (NCCZO NPs) after a certain period exhibited good resistance against tubeworms and barnacle formation due to the hydroxyl and amine functional groups (El-saied & Ibrahim, 2020). Hence it can be summarized that the co-precipitation route utilizes a cross-linker to obtain a better morphology, stability, and a physical cross-linking network of molecular chain arrangements with hydrogen bonding.…”

This review discusses the increasing potential of chitosan nanocomposites as viable materials capable of targeting these debilitating factors. This review focuses on various techniques used to process chitosan nanocomposites and their mechanical properties. Chitosan nanocomposites are regarded as highly effective antimicrobials for the treatment of chronic wounds. Chitosan nanocomposites, such as chitosan/polyethylene and oxide/silica/ciprofloxacin, demonstrate efficient antibacterial activity and exhibit no cytotoxicity against Human Foreskin Fibroblast Cell Lines (HFF2). Other studies have also showcased the capacity of chitosan nanocomposites to accelerate and improve tissue regeneration through increment in the number of fibroblast cells and angiogenesis and reduction of the inflammation phase. The layer-by-layer technique has benefits, ensuring its suitability in preparing chitosan nanocomposites for drug delivery and wound dressing applications. While the co-precipitation route requires a cross-linker to achieve stability during processing, the solution-casting route can produce stable chitosan nanocomposites without a cross-linker. By using the solution casting method, fillers such as multi-walled carbon nanotubes (MWCNTs) and halloysite nanotubes (HTs) can be uniformly distributed in the chitosan, leading to improved mechanical properties. The antibacterial effects can be achieved with the introduction of AgNPs or ZnO. With the increasing understanding of the biological mechanisms that control these diseases, there is an influx in the introduction of novel materials into the mainstream wound care market.

“…Biofouling is a severe problem affecting industrial unit operations, especially in developing nations. It begins with bacteria settling onto a rock layer, and environmental factors such as weather, temperature, sunlight, salinity, turbidity, and substrate structure enhance its development 2,3 . This leads to increased costs associated with fuel consumption, paint removal and repainting, and environmental compliance measures.…”

“…nano-sized chitosan with a large surface area improves antifouling activity. 3,4 The advancements in the process of synthesis, manufacture, and stabilization of metal nanoparticles have led to a new cohort of commodities as well as augmented nanoscience research. In areas with several altered species of organisms in biofouling formation, nano-particle coatings are exposed to several physical and biological factors, and it is essential to test them in the relevant conditions to demonstrate their antifouling activity.…”

Biofouling poses a significant economic challenge for marine transportation. The use of chemical compounds to eliminate fouling layers beneath the ship's surface, albeit effective, raises concerns due to its potential harm to the aquatic ecosystem. Lichen symbiotic associations, an underexplored research area, show promise in producing antimicrobial and antifouling compounds. These lichen‐associated bacteria engage in various functional activities and have multiple bacterial counterparts. The optimal conditions for cultivating lichen‐associated bacteria for maximum growth were identified as a pH of 7, a temperature of 30°C, and an incubation period of 8 days. Glucose served as the carbon source, while yeast extract served as the nitrogen source. Additionally, zinc nanoparticles were successfully synthesized from the thriving lichen‐associated bacteria. Fourier transform infrared spectroscopy (FTIR) analysis indicated distinctive bands at 3890 and 3103 cm−1, corresponding to the OH stretching of alcohol and acid stretch bands, respectively. Furthermore, the presence of amide in NH banding in the synthesized zinc nanoparticles was represented by a band at 1636 cm−1. SEM images of the produced zinc NPs displayed a spherical shape, ranging in size from 40 to 70 nm. To assess the impact of these nanoparticles from lichen‐associated bacteria on biofouling activity in marine transportation, zebrafish results were analyzed.
