“…Feng et al [ 38 ] investigated the antifouling properties of 18 alkaloids extracted from terrestrial plants, and a 1-year marine field antifouling study showed that camptothecin could significantly inhibit the adhesion of marine fouling organisms. Subsequently, the degradability and environmental risks associated with the use of camptothecin as a novel marine natural antifouling agent under marine environmental conditions were further evaluated [ 39 ], which showed that camptothecin can be rapidly decomposed under light, while the mean environmental concentration (PEC)/no effect concentration (PNEC) values of camptothecin were well below 1, indicating that the environmental risks associated with the use of camptothecin as a marine antifouling agent were low. This naturally active substance has excellent application prospects in the field of marine antifouling.…”

Any equipment submerged in the ocean will have its surface attacked by fouling organisms, which can cause serious damage. Traditional antifouling coatings contain heavy metal ions, which also have a detrimental effect on the marine ecological environment and cannot fulfill the needs of practical applications. As the awareness of environmental protection is increasing, new environmentally friendly and broad-spectrum antifouling coatings have become the current research hotspot in the field of marine antifouling. This review briefly outlines the formation process of biofouling and the fouling mechanism. Then, it describes the research progress of new environmentally friendly antifouling coatings in recent years, including fouling release antifouling coatings, photocatalytic antifouling coatings and natural antifouling agents derived from biomimetic strategies, micro/nanostructured antifouling materials and hydrogel antifouling coatings. Highlights include the mechanism of action of antimicrobial peptides and the means of preparation of modified surfaces. This category of antifouling materials has broad-spectrum antimicrobial activity and environmental friendliness and is expected to be a new type of marine antifouling coating with desirable antifouling functions. Finally, the future research directions of antifouling coatings are prospected, which are intended to provide a reference for the development of efficient, broad-spectrum and green marine antifouling coatings.

“…After tributyltin was forbidden by the International Maritime Organization, copper-based and zinc-based inorganic antibacterial agents dominated the marketing (Alzieu, 2000;Amara et al, 2018). Moreover, as most natural organic antifoulants have ecofriendly features, they have been developed rapidly in recent years, such as capsaicin and camptothecin (Hao et al, 2020(Hao et al, , 2022a. In designing antifoulants, researchers have focused on how to kill the fouling organisms and inhibit the growth and reproduction of organisms near the surfaces of the submarine substrate.…”

Matrine@chitosan-D-proline nanocapsules as antifouling agents with antibacterial properties and biofilm dispersibility in the marine environment

et al. 2022

Antifoulants are the most vital substances in antifouling coatings to prevent marine organisms from colonizing the undersea substrate surfaces. In addition to antibacterial performance, inhibition of biofilm formation is an important criterion for antifouling coatings. In this study, we synthesized pH-responsive matrine@chitosan-D-proline (Mat@CS-Pro) nanocapsules of about 280 nm with antibacterial properties and biofilm dispersibility. The prepared Mat@CS-Pro nanocapsules exhibited high-level antibacterial properties, reaching about 93, 88, and 96% for E. coli, S. aureus, and P. aeruginosa, respectively. Such nanocapsules can cause irreversible damage to bacteria and cause them to lose their intact cell structures. Moreover, Mat@CS-Pro nanocapsules also possessed outstanding dispersal biofilm performances, in which the biofilm thickness of E. coli, S. aureus, and P. aeruginosa was decreased by 33, 74, and 42%, respectively, after 3 days of incubation. Besides, the Mat@CS-Pro nanocapsules had remarkable pH-responsive properties. As the environmental pH became acidic, the nanocapsules swelled to about 475 nm and the released concentration could reach 28.5 ppm after immersion for 10 h but maintained a low releasing rate in pH 8 conditions.
