“…There are alternatives available to impede the rate at which fouling organisms colonize submerged vessel surfaces that are less harmful to the environment (and non-target organisms) than those traditionally adopted. Such alternatives include the use of non-toxic, non-stick, fouling-release coatings [273], fouling-release fluorinated polymers, and silicon and amphiphilic surfaces [274], biodegradable polymers, and natural antifoulants such as butenolide derived from marine bacteria [275] and various naturally based biodegradable polymers, such as from cashew nut shell liquid, incorporating natural antifouling products, for example zosteric acid (sourced from marine plants), isocyanoterpenes (sourced from sponges and nudibranchs) and mangrove tannins (sourced from the mangrove plants) [276].…”

Boating and shipping operations, their associated activities and supporting infrastructure present a potential for environmental impacts. Such impacts include physical changes to bottom substrate and habitats from sources such as anchoring and mooring and vessel groundings, alterations to the physico-chemical properties of the water column and aquatic biota through the application of antifouling paints, operational and accidental discharges (ballast and bilge water, hydrocarbons, garbage and sewage), fauna collisions, and various other disturbances. Various measures exist to sustainably manage these impacts. In addition to a review of associated boating- and shipping-related environmental impacts, this paper provides an outline of the government- and industry-related measures relevant to achieving positive outcomes in an Australian context. Historically, direct regulations have been used to cover various environmental impacts associated with commercial, industrial, and recreational boating and shipping operations (e.g., MARPOL). The effectiveness of this approach is the degree to which compliance can be effectively monitored and enforced. To be effective, environmental managers require a comprehensive understanding of the full range of instruments available, and the respective roles they play in helping achieve positive environmental outcomes, including the pros and cons of the various regulatory alternatives.

“…Since then, some booster biocides, such as Irgarol 1051 or Sea-nine 211, in combination with copper, have been used; nevertheless, even these compounds have demonstrated toxicity on living organisms. Therefore, it is imperative to find new antifouling (AF) compounds with environmentally safe characteristics [ 4 , 5 , 6 ]. Several non-toxic marine natural products with AF activity have been reported; among them, some flavonoids presented potential AF activity and low toxicity, suggesting their potential as new lead compounds for the development of new AF agents [ 7 ].…”

Over the last decades, antifouling coatings containing biocidal compounds as active ingredients were used to prevent biofouling, and eco-friendly alternatives are needed. Previous research from our group showed that polymethoxylated chalcones and glycosylated flavones obtained by synthesis displayed antifouling activity with low toxicity. In this work, ten new polymethoxylated flavones and chalcones were synthesized for the first time, including eight with a triazole moiety. Eight known flavones and chalcones were also synthesized and tested in order to construct a quantitative structure-activity relationship (QSAR) model for these compounds. Three different antifouling profiles were found: three compounds (1b, 11a and 11b) exhibited anti-settlement activity against a macrofouling species (Mytilus galloprovincialis), two compounds (6a and 6b) exhibited inhibitory activity against the biofilm-forming marine bacteria Roseobacter litoralis and one compound (7b) exhibited activity against both mussel larvae and microalgae Navicula sp. Hydrogen bonding acceptor ability of the molecule was the most significant descriptor contributing positively to the mussel larvae anti-settlement activity and, in fact, the triazolyl glycosylated chalcone 7b was the most potent compound against this species. The most promising compounds were not toxic to Artemia salina, highlighting the importance of pursuing the development of new synthetic antifouling agents as an ecofriendly and sustainable alternative for the marine industry.

“…This has prompted academic and commercial interest in seeking out new approaches to preventing, reducing, or mitigating the effects of biofouling or biofilm development, particularly in the marine environment, or in membrane technology for water separation, for example [ 19 ]. Kyei et al have recently reviewed the currently available methods for preventing and mitigating growth of algal and other organisms on marine structures in an environmentally friendly and cost-effective (and legal) manner [ 20 ].…”

The term ‘biomimetic’ might be applied to any material or process that in some way reproduces, mimics, or is otherwise inspired by nature. Also variously termed bionic, bioinspired, biological design, or even green design, the idea of adapting or taking inspiration from a natural solution to solve a modern engineering problem has been of scientific interest since it was first proposed in the 1960s. Since then, the concept that natural materials and nature can provide inspiration for incredible breakthroughs and developments in terms of new technologies and entirely new approaches to solving technological problems has become widely accepted. This is very much evident in the fields of materials science, surface science, and coatings. In this review, we survey recent developments (primarily those within the last decade) in biomimetic approaches to antifouling, self-cleaning, or anti-biofilm technologies. We find that this field continues to mature, and emerging novel, biomimetic technologies are present at multiple stages in the development pipeline, with some becoming commercially available. However, we also note that the rate of commercialization of these technologies appears slow compared to the significant research output within the field.
