“…Several methods including photolithography, etching, laser microfabrication, templating or hot embossing are currently used to micropattern solid substrates such as metals or polymers. [24,28,49,[151][152][153] The most common method used to pattern substrates for antifouling applications in the literature is the association of photolithography and etching process to create a mold in which the wanted textured material is cast. Every method of fabrication has its advantages, drawbacks, and resolution (Table 2).…”

“…Those coatings release chemicals or enzymatic compounds in water and affect targeted biofoulers but also nontargeted biofoulers; [23,24] and ii) nontoxic coatings, aiming to inhibit settlement and/or increase the release of settled organisms. [2,22,[25][26][27][28] Engineered microtopographies, fouling-release coatings (FRC), or superhydrophobic (-philic) materials can be found in that category. [26] FRC, in opposite with usually used antifouling solutions, does not release biocides.…”

the hulls could limit the undesirable effects but together increase the costs both in time and money. Consequently, biofouling is costing billions of dollars each year to naval industry. [8,9] When talking about colonization on marine sensors, Delauney et al. showed that biofouling affected the sensitivity and caused drift of measurements of the device over time. [10] Biofouling is also a big issue in the case of renewable marine energy devices. Biofouling on wave energy converters (WEC) leads to the decrease in efficiency of the devices by increasing drag and is also responsible of local biocorrosion. [11,12] The maintenance of such structure is risky and expensive, requiring period of good weather and calm sea state, among others. [13] Maintenance is all the more necessary during summer when fouling is the most intensive, due to higher seawater temperature, solar irradiation, and number of organisms. [13,14] In aquaculture, biofouling is also a major concern. Fitridge et al. reviewed all the effect of marine biofouling and its control in aquaculture. [15] Indeed, it can be responsible of cage deformation and structural fatigue, it will reduce the quality of water by limiting oxygen availability or increase the disease risk for fish species. Considering shellfish, biofouling can be responsible of mortality, shell erosion, competition for food and space, or disturbance in shell growth, for instance.In desalination plants, settlement, and accumulation of foulers onto the surface of the membranes or its pores lead to a deterioration of the filter. Salt rejection is negatively affected by the degradation of the membrane due to fouling. [16] Preventing fouling appears consequently a major concern for naval and marine industry, including sustainable domains like aquaculture, desalination plant, or the development of marine renewable energy devices.Protecting marine infrastructures has been the main matter of concern since the beginning of maritime transports. Tar, wax, arsenic, asphalt, or pitch are thought to be components used during antiquity for the first antifouling coatings. [3,5] Phoenicians and Carthaginians possibly used copper plates to protect their ships. [3,5] In the early 18th century, boats started to be made of steel. Zinc, nickel, and lead were chosen instead of copper plates to protect ships, because of corrosion matter. [3,17] From the late 18th century, heavy metal were more and more Marine biofouling is the unwanted accumulation of biological origin matters on submerged surfaces. Biofouling is a major economic burden on navy and commercial ships, as well as civil structures, piping systems, sensors, and power generating facilities. Due to the vast variety of marine organisms that colonize submerged surfaces, no surface has been found that is completely resistant to marine biofouling. The development of bioinspired and textured surfaces and their effects on marine biofouling are reviewed here. Different parameters such as mechanical properties, wettability, and surface topo graphy are shown to have...

“…Fabrication of these surfaces has been inspired by the excellent anti-adhesive structures found on natural surfaces of insect wings, marine organisms, gecko foot, and lotus leaf. 98,99 The presence of micro- and nanoscale architectures on the insect wings allows antimicrobial properties. Similarly, biomaterial surfaces with suitable topographical features for controlling cell adhesion can be fabricated using physical modification techniques such as photolithography, demixing, dewetting, physical vapor deposition, laser surface modification, sand blasting, and ion beam assisted deposition.…”

Rapidly growing viral infections are potent risks to public health worldwide. Accessible virus-specific antiviral vaccines and drugs are therapeutically inert to emerging viruses, such as Zika, Ebola, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Therefore, discovering ways to prevent and control viral infections is among the foremost medical challenge of our time. Recently, innovative technologies are emerging that involve the development of new biomaterial-based formulations and surfaces endowed with broad-spectrum antiviral properties. Here, we review emerging biomaterials technologies for controlling viral infections. Relevant advances in biomaterials employed with nanotechnology to inactivate viruses or to inhibit virus replication and further their translation in safe and effective antiviral formulations in clinical trials are discussed. We have included antiviral approaches based on both organic and inorganic nanoparticles (NPs), which offer many advantages over molecular medicine. An insight into the development of immunomodulatory scaffolds in designing new platforms for personalized vaccines is also considered. Substantial research on natural products and herbal medicines and their potential in novel antiviral drugs are discussed. Furthermore, to control contagious viral infections, i.e., to reduce the viral load on surfaces, current strategies focusing on biomimetic anti-adhesive surfaces through nanostructured topography and hydrophobic surface modification techniques are introduced. Biomaterial surfaces functionalized with antimicrobial polymers and nanoparticles against viral infections are also discussed. We recognize the importance of research on antiviral biomaterials and present potential strategies for future directions in applying these biomaterial-based approaches to control viral infections and SARS-CoV-2.

“…Bioinspired strategies for antibiofouling materials have been developed by mimicking the topology of natural materials or by employing biobased substances. [ 22–34 ] Nanostructured cauliflower‐like [ 35 ] or nanoflower‐like [ 36 ] metallic substrates were resistant to platelet adhesion or protein adsorption due to their superomniphobic properties. Antifouling against bacterial adhesion was obtained on shark skin‐like [ 37 ] or ray skin‐like [ 38 ] microtopography on polydimethylsiloxane (PDMS) elastomers.…”

Biofouling on surfaces immersed in aquatic environment induces catastrophic corrosion of metallic materials in petrochemical infrastructures, maritime facilities, and power plants. To combat the synergistic effect of biofouling and corrosion on the deterioration of metallic materials, smart coatings possessing a dual function of antibiofouling and anticorrosion properties are needed. Herein, redox‐responsive copolymer conjugates are synthesized and employed as coatings with the dual function of biofouling and corrosion mitigation. The dual function of copolymers is attributed to fluorinated units and the corrosion inhibitor 2‐mercaptobenzothiazole (MBT) conjugated via disulfide linkages. Indeed, the disulfide linkages can be cleaved in a reducing environment, yielding controlled release of the corrosion inhibitor MBT during corrosion process. The antibiofouling action against protein adsorption and algal attachment is enabled by cooperation of the repellent characteristic of fluorinated moieties and the biocidal effect of conjugated MBT.
