“…[180] Hydrogel coatings with slow release of antifoulants can also be used to protect marine sensors from adhesion of bacterial biofilms or barnacles. [181] In such cases, where the gel will ideally protect the sensor for an extended time, the mechanical performance of the gel would be important.…”

Hydrogels have applications in surgery and drug delivery, but are never considered alongside polymers and composites as materials for mechanical design. This is because synthetic hydrogels are in general very weak. In contrast, many biological gel composites, such as cartilage, are quite strong, and function as tough, shock‐absorbing structural solids. The recent development of strong hydrogels suggests that it may be possible to design new families of strong gels that would allow the design of soft biomimetic machines, which have not previously been possible.

“…Solid surfaces, when exposed to sea water, undergo a series of changes leading to the generation of a complex layer formed as a result of adhesion by marine organisms, mainly consisting of microbial slimes, diatoms, barnacles, tunicates, bryozoans and spores of marine algae (Rasmussen and Østgaard 2003;Bhosale et al 2002;Elvers and Lappin-Scott 2000;John et al 1999;Abarzua et al 1999;Abarzua and Jakubowski 1995;Mary et al 1993;Szewzyk et al 1991;Henschell and Cook 1990;Characklis 1981). This phenomenon is known as biofouling.…”

“…the formation of the exopolysaccharide (EPS) layer, one of the distinct features of a developed biofilm (Costerton 1995;Danese et al 2000). It is believed that the extracellular polymeric substances (EPS) play an important role in the adhesion of bacteria to the surfaces (Rasmussen and Østgaard 2003;Danese et al 2000;Costerton 1995). The presence of adhesive substances and rough irregular microbial colonies gradually starts trapping more particles and organisms.…”

Marine algae are one of the largest producers of biomass in the marine environment. They produce a wide variety of chemically active metabolites in their surroundings, potentially as an aid to protect themselves against other settling organisms. These active metabolites, also known as biogenic compounds, produced by several species of marine macro- and micro-algae, have antibacterial, antialgal, antimacrofouling and antifungal properties, which are effective in the prevention of biofouling, and have other likely uses, e.g. in therapeutics. The isolated substances with potent antifouling activity belong to groups of fatty acids, lipopeptides, amides, alkaloids, terpenoids, lactones, pyrroles and steroids. These biogenic compounds have the potential to be produced commercially using metabolic engineering techniques. Therefore, isolation of biogenic compounds and determination of their structure could provide leads for future development of, for example, environmentally friendly antifouling paints. This paper mainly discusses the successes of such research, and the future applications in the context of understanding the systems biology of micro-algae and cyanobacteria.

“…It is therefore likely that alginate has already achieved adsorption on the surfaces of the coatings prior to the adherence of E. coli. Due to the hydrophilic nature of alginate and calcium alginate [50,51], they are able to readily form a highly hydrophilic surface upon their adsorption on the surfaces of the samples. Consequently, numerous water molecules together with the highly hydrophilic surface produce a hydration layer.…”
