Our research aims to study the properties of real shark skin in accordance with its topographical features and the biomimicry for friction reduction. In this paper, we are focusing on antifouling surface modification based on the surface roughness and frictional resistance inspired from the shark's denticule arrangements. Biomimetic shark skins were prepared using the silicone laminated transfer molding method to investigate the antifouling effects. Anti-algae formations were investigated to examine and assess the antifouling properties of the biomimetic shark skin surface microstructure. The results indicated that the effect of microreplication with shark skin on the surface had reduced 13% -40% of algae formation. The characteristics of the hydrophobic properties for shark skin had also been investigated through the analysis of the contact angle (CA). Scanning electron microscopy (SEM) is used to observe the surfaces morphologies of the shark skin as well as the biomimetic shark skin. In addition to that, the frictional resistance experiment was carried out to evaluate the friction of coefficient (COF) of different surface modifications. The frictional resistance experiment for real shark skin and replicated shark skin demonstrated lowered COF value ranging from μ = 0 to 1, compared to the COF for controlled surface whereby the value ranges from μ = 0 to 5.

“…Nanometric surfaces were inspired by antibacterial activities seen in nature, such as those that occur in lotuses, cicadae, sharks, butterflies, and among others, dragonfly wings [ 35 , 52 ]. Recent studies [ 75 , 76 ] attempt to replicate these patterns by developing surfaces for future application in the biomedical field, such as PMMA surfaces designed as shark skin-patterned [ 75 ], and zirconium-based bulk metallic glasses [ 76 ]. However, this area of research is still in its infancy and further studies are needed before these materials can be used.…”

Highlights Bacterial adhesion to the surface of dental materials play a significant role in infections. The factors that govern microbial attachment involves different types of physical-chemical interactions and biological processes. Studying bacterial adhesion makes it possible to understand the mechanisms involved in attachment and helps in the search for technologies that promote antibacterial surfaces.

“…By targeting the attachment and/or multiplication stage, the formation or maturation of the biofilm will be inhibited. For example, altering the molecular composition or charge of a surface may hinder the attachment stage, and thus stop further biofilm formation [ 23 , 24 , 25 , 26 , 27 ]. In this context, the development of therapeutic inhibitors of sortase A, a membrane protein involved in anchoring of surface-exposed proteins, have received great research attention, as the inhibition of this protein will greatly alter the surface properties of the bacterial cells [ 169 , 170 , 171 , 172 ].…”

“…Indwelling medical devices are also particularly exposed to bacterial biofilm formation due to their surfaces, making them excellent supports for bacterial adhesion [ 21 ]. Intense research efforts have therefore been devoted to developing strategies to prevent biofilm formation on such surgical devices, either by passively preventing bacterial colonization (e.g., surface engineering) or by actively inhibiting bacterial growth (e.g., antimicrobial coating) [ 22 , 23 , 24 , 25 , 26 , 27 ]. In human infections, the main source of staphylococcal contamination is their natural presence on the human skin.…”

Staphylococcal Biofilms: Challenges and Novel Therapeutic Perspectives

et al. 2021

Staphylococci, like Staphylococcus aureus and S. epidermidis, are common colonizers of the human microbiota. While being harmless in many cases, many virulence factors result in them being opportunistic pathogens and one of the major causes of hospital-acquired infections worldwide. One of these virulence factors is the ability to form biofilms—three-dimensional communities of microorganisms embedded in an extracellular polymeric matrix (EPS). The EPS is composed of polysaccharides, proteins and extracellular DNA, and is finely regulated in response to environmental conditions. This structured environment protects the embedded bacteria from the human immune system and decreases their susceptibility to antimicrobials, making infections caused by staphylococci particularly difficult to treat. With the rise of antibiotic-resistant staphylococci, together with difficulty in removing biofilms, there is a great need for new treatment strategies. The purpose of this review is to provide an overview of our current knowledge of the stages of biofilm development and what difficulties may arise when trying to eradicate staphylococcal biofilms. Furthermore, we look into promising targets and therapeutic methods, including bacteriocins and phage-derived antibiofilm approaches.
