Sustainable Biofilm Inhibition Using Chitosan-Mesoporous Nanoparticle-Based Hybrid Slippery Composites

“…36−39 In addition, a replenishment function that can release the oil layer from the inside and restore its function over time has been studied. 35,40 However, even with these approaches, once bacteria settle directly on the surface before the oil layer is replenished, they will accelerate the further development of the biofilm, resulting in the loss of antifouling function over the surface. 41,42 In essence, the ongoing challenge lies in developing biofilm inhibition technologies that simultaneously provide robust and sustainable antifouling functions over long periods without the use of toxic and environmentally harmful materials, requiring further advancements in the field.…”

“…Recently, inspired by the lubricating functions of natural organisms such as pitcher plants, algae, and loach skin, biomimetic slippery liquid-infused porous surfaces (SLIPS) have been introduced as a strong candidate for nontoxic antifouling technology. , SLIPS, which typically consist of a porous structure, can contain a thin lubricant layer on their surface that is immiscible with external fluids and substances due to the low surface tension . Contrary to previous studies, SLIPS prevent the fundamental attachment of bacteria based on their slippery properties. , Although the surface lubricant layer provides a surface environment that is completely isolated from external contaminants in a nontoxic manner, lubricants are easily depleted by physical contact or shear flow, resulting in the degradation or depletion of their lubricating functions. − To improve the long-term use of SLIPS, several studies have introduced liquid-infused surfaces with improved oil absorption capacity based on the integration of silica (SiO 2 ), titania (TiO 2 ), and carbon (C) porous nanoparticles. − In addition, a replenishment function that can release the oil layer from the inside and restore its function over time has been studied. , However, even with these approaches, once bacteria settle directly on the surface before the oil layer is replenished, they will accelerate the further development of the biofilm, resulting in the loss of antifouling function over the surface. , In essence, the ongoing challenge lies in developing biofilm inhibition technologies that simultaneously provide robust and sustainable antifouling functions over long periods without the use of toxic and environmentally harmful materials, requiring further advancements in the field.…”
