Combining Topography and Chemistry to Produce Antibiofouling Surfaces: A Review

Abstract

Despite decades of research on the reduction of surface fouling from biomolecules or micro-organisms, the ultimate antibiofouling surface remains undiscovered. The recent covid-19 pandemic strengthened the crucial need for such treatments. Among the numerous approaches that are able to provide surfaces with antibiofouling properties, chemical, biological, and topographical strategies have been implemented for instance in the marine, medical, or food industries. However, many of these methods have a biocidal effect and, with antibioresistance and biocide resistance a growing threat on humanity, strategies based on reducing adsorption of biomolecules and micro-organism are necessary for long-term solutions. Bioinspired strategies, combining both surface chemistry and topography, are currently at the heart of the best innovative and sustainable solutions. The synergistic effect of micro/nanostructuration, together with engineered chemical or biological functionalization is believed to contribute to the development of antibiofouling surfaces. This review aims to present approaches combining hydrophobic or hydrophilic chemistries with a specific topography to avoid biofouling in various industrial environments and healthcare facilities.

Progress in the regulation of pathological crystallization

“…There are also methods that achieve chemical modification and surface topography in one step. 93 Coatings are widely used in medical devices, such as urinary catheters, intraocular lenses, and cardiac stents. Most of the current medical coatings are superhydrophilic, such as hyperbranched polyethylene glycol, zwitterionic copolymers, heparin, and hydrogels.…”

Recent Advances in Superhydrophobic and Antibacterial Cellulose-Based Fibers and Fabrics: Bio-inspiration, Strategies, and Applications

“…Bhandari et al [ 46 ] summarized the use of metal nanoparticles for antimicrobial finishes on textiles. The developments of anti-biofouling surfaces prepared by combining surface topography and chemistry have also been summarized [ 47 , 48 ]. The works on cellulose fabrics with super-hydrophobic surfaces imparting unique anti-biofouling and contact killing or biocide leaching properties are seldom reviewed.…”

Unraveling the Adhesion Behavior of Different Cell Lines on Biomimetic PEDOT Interfaces: The Role of Surface Morphology and Antifouling Properties

“…35 As reported in previous studies, the hydrophilicity of antifouling coatings on surfaces with nano or microscale patterns exhibited a notable enhancement due to the larger contact area. 36,37 Both topography and chemistry can contribute to hydrophilicity; as a result, the morphology and chemistry tunable PEDOT offer a way to manipulate and understand the interaction between a conducting polymeric interface and biomolecules.…”
