Protein fouling on critical biointerfaces causes significant public health and clinical ramifications. Multiple strategies, including superhydrophobic (SHP) surfaces and coatings, have been explored to mitigate protein adsorption on solid surfaces. SHP materials with underwater air plastron (AP) layers hold great promise by physically reducing the contact area between a substrate and protein molecules. However, sustaining AP stability or lifetime is crucial in determining the durability and long-term applications of SHP materials. This work investigated the effect of protein on the AP stability using model SHP substrates, which were prepared from a mixture of silica nanoparticles and epoxy. The AP stability was determined using a submersion test with real-time visualization. The results showed that AP stability was significantly weakened by protein solutions compared to water, which could be attributed to the surface tension of protein solutions and protein adsorption on SHP substrates. The results were further examined to reveal the correlation between protein fouling and accelerated AP dissipation on SHP materials by confocal fluorescent imaging, surface energy measurement, and surface robustness modeling of the Cassie–Baxter to Wenzel transition. The study reveals fundamental protein adsorption mechanisms on SHP materials, which could guide future SHP material design to better mitigate protein fouling on critical biointerfaces.

“…The biofouling layer could be problematic in food-processing plants because it greatly decreases operating efficiency, unnecessarily increases the run-time, energy consumption, corrosion rates, and maintenance costs. 184 The vast majority of food industries use resource and labor-intense sanitation regimes to disrupt or kill the already-established biofilm on food-contact surfaces. 23 For example, many food industries use different chemical-derived sanitization or sterilization strategies to decontaminate foodcontact surfaces.…”

The adhesion of sticky liquid foods to a contacting surface can cause many technical challenges. The food manufacturing sector is confronted with many critical issues that can be overcome with long-lasting and highly nonwettable coatings. Nanoengineered biomimetic surfaces with distinct wettability and tunable interfaces have elicited increasing interest for their potential use in addressing a broad variety of scientific and technological applications, such as antifogging, anti-icing, antifouling, antiadhesion, and anticorrosion. Although a large number of nature-inspired surfaces have emerged, food-safe nonwetted surfaces are still in their infancy, and numerous structural design aspects remain unexplored. This Review summarizes the latest scientific research regarding the key principles, fabrication methods, and applications of three important categories of nonwettable surfaces: superhydrophobic, liquid-infused slippery, and re-entrant structured surfaces. The Review is particularly focused on new insights into the antiwetting mechanisms of these nanopatterned structures and discovering efficient platform methodologies to guide their rational design when in contact with food materials. A detailed description of the current opportunities, challenges, and future scaleup possibilities of these nanoengineered surfaces in the food industry is also provided.

Nanocrystalline diamonds (NCDs) are one of the many carbon allotropes that have attracted great attention for the advancement of many technologies owing to their superior mechanical, thermal, and optical properties. Yet, their synthesis must be improved for availability at low costs and their widespread application. Here, we report the atmospheric-pressure flame vapor deposition (FVD) synthesis of NCD particles and thin films over an area of more than 27 cm2 using methane–hydrogen–air flat flames. Synthesis at atmospheric pressure is beneficial as it can lower costs and be more time-efficient when compared to the batch-by-batch synthesis of low-pressure and high-pressure processes. Also, the abundance of methane gas available can further lower costs and improve scalability, while generating lower flame temperatures to mitigate the need of extensive cooling. Notably, the FVD method unlocks conditions for diamond growth beyond the previously considered diamond-growth region of the C–H–O phase diagram. By modeling the flame radical species as a guidance, we experimentally demonstrate that the FVD growth of NCDs can be facilely controlled by tuning the reactant gas composition, substrate material, and seeding density. Moreover, we show that the addition of an external electric bias was influential in controlling the porosity and thickness of the NCD films. Overall, with the low cost and simplicity for operation without the need of vacuum, this atmospheric-pressure FVD approach will offer opportunities to facilitate the scaling-up of NCD synthesis for applications in optical, tribological, thermal, and biomedical coatings.
