“…The creation of liquid layers using materials containing known therapeutic or antimicrobial components may also be an area of interest. For example, a liquid‐infused substrate incorporating silver ions may function as an enhanced microbial‐repellent surface, given that silver is known to have antimicrobial properties . Furthermore, recent work demonstrating the ability of membranes coated with liquid layers to selectively separate gases from liquids flowing through tubing may prove useful in the reduction of incidences of air embolisms, which can result from some invasive medical procedures such as cardiothoracic and neurosurgery as well as deep‐water diving …”

The development of new technologies is key to the continued improvement of medicine, relying on comprehensive materials design strategies that can integrate advanced therapeutic and diagnostic functions with a variety of surface properties such as selective adhesion, dynamic responsiveness, and optical/mechanical tunability. Liquid-infused surfaces have recently come to the forefront as a unique approach to surface coatings that can resist adhesion of a wide range of contaminants on medical devices. Furthermore, these surfaces are proving highly versatile in enabling the integration of established medical surface treatments alongside the antifouling capabilities, such as drug release or biomolecule organization. Here, the range of research being conducted on liquid-infused surfaces for medical applications is presented, from an understanding of the basics behind the interactions of physiological fluids, microbes, and mammalian cells with liquid layers to current applications of these materials in point-of-care diagnostics, medical tubing, instruments, implants, and tissue engineering. Throughout this exploration, the design parameters of liquid-infused surfaces and how they can be adapted and tuned to particular applications are discussed, while identifying how the range of controllable factors offered by liquid-infused surfaces can be used to enable completely new and dynamic approaches to materials and devices for human health.

“…[9e] A recent example to be highlighted includes Shiratori and co-workers, who developed a robust SLIPS with the lubricant covalently bonded to the underlying LBL substrate. [46] Another design principle aimed at the increase of longterm stability of SLIPS is based on the regeneration of the lubricated film through the self-secretion or resupply of the lubricant by "vascularization" of the material. Thus, Howell et al introduced a 3D "vascular system" into a PDMS substrate functioning as a lubricant reservoir to replenish lubricant.…”

Bioinspired lubricant-infused surfaces exhibit various unique properties attributed to their liquid-like and molecularly smooth nature. Excellent liquid repellency and "slippery" properties, self-healing, antiicing, anticorrosion characteristics, enhanced heat transfer, antibiofouling, and cell-repellent properties have been already demonstrated. This progress report highlights some of the recent developments in this rapidly growing area, focusing on properties of lubricant-infused surfaces, and their emerging applications as well as some future challenges.coatings. [8] In order to solve the abovementioned limitations of traditional superhydrophobic and superoleophobic surfaces, Quéré, Aizenberg, and Varanasi proposed bioinspired slippery liquidinfused porous surface (SLIPS) or lubricant-impregnated surfaces combining the mechanical stability of a solid substrate with the liquid-like properties and molecularly smoothness of the lubricant interface. [9a-d] It should be noted that stabilization of a lubricant layer on solid surfaces by forming a thin polymer film that can be swollen in the lubricant was introduced in 1988 by Karakelle and Zdrahala from Bekton, Dickinson and Company.[9e] They also demonstrated excellent long-term stability, liquid repellency, and proposed various medical applications of lubricant-impregnated surfaces. SLIPSs mimic the Nepenthes pitcher plant surface, [10] which is textured and can be lubricated with an aqueous solution. [11] The unique slippery character of the [9a] Nepenthes pitcher plant's surface resulting from water lubrication helps it capture insects sliding into its interior. To mimic the Nepenthes pitcher plant surface, a lubricating hydrophobic liquid can be infused into different hydrophobic porous or rough substrates to form SLIPS. [9] By matching the surface energy of the underlying porous substrate and the hydrophobic lubricant, the liquid can be stabilized on the surface of the substrate to form SLIPS. [9a] Depending on the impregnated lubricant, SLIPSs possess excellent repellency and drop mobility to a broad range of liquids including low surface tension liquids, and complex fluids such as blood or cell medium. [9a] This liquid repellency as well as SLIPS′ self-healing properties are due to the mobility of the lubricant trapped inside the porous surface structures. [12] Lubricant-infused surfaces demonstrated icephobic, stainresistant, biofilm-or cell-repellent or marine antibiofouling properties as well as tolerance to high pressure and transparency. [9,13] All of these unique properties make SLIPS interesting for the development of novel functional materials and various practical applications.The goal of this progress report is not to comprehensively review this broad and dynamic research field but rather highlight selected important aspects that have been less reviewed so far despite their potential. Some important and related papers could not be cited due to the length limitations. We also refer readers to several excellent reviews covering applications of ...

“…The fabrication of SLIPSs to work as icephobic media requires an accurate design of the system to provide reliable working performance. All the different interactions involvedsurface–lubricant, lubricant–water, and surface–watermust be balanced to weaken the ice adhesion while, at the same time, limiting the damage to the surface and lubricant leakage. − To do so, the porous surface that serves as a host must be mechanically robust, have a large specific surface, and be affine to the chosen lubricant to be easily impregnated while efficiently repelling water. Despite the simple preparation method, candle soot revealed to be an ideal substrate for the fabrication of surfaces with such characteristics .…”

Unwanted icing has major safety and economic repercussions on human activities, affecting means of transportation, infrastructures, and consumer goods. Compared to the common deicing methods in use today, intrinsically icephobic surfaces can decrease ice accumulation and formation without any active intervention from humans or machines. However, such systems often require complex fabrication methods and can be costly, which limits their applicability. In this study, we report the preparation and characterization of several slippery lubricant-infused porous surfaces (SLIPSs) realized by impregnating with silicone oil a candle soot layer deposited on double-sided adhesive tape. Despite the use of common household items, these SLIPSs showed anti-icing performance comparable to other systems described in the literature (ice adhesion < 20 kPa) and a good resistance to mechanical and environmental damages in laboratory conditions. The use of a flexible and functional substrate as tape allowed these devices to be stretchable without suffering significant degradation and highlights how these systems can be easily prepared and applied anywhere needed. In addition, the possibility of deforming the substrate can “allow” the application of SLIPS technology in mechanical ice removal methodologies, drastically incrementing their performance.
