“…This behavior is inline with studies from literature focusing on liquid‐infused surfaces having an anti‐corrosion effect. [ 31,32 ] The pitting potentials (Figure S4, Supporting Information) of Nano‐Au, Nano‐Au‐FS, and L‐Nano‐Au‐FS are in a similar range (0.69, 0.66, 0.69 V). This shows that the nanostructured Au can be exposed to the electrolyte even though the lubricating layer exists.…”

There is a need for point‐of‐care bacterial sensing and identification technologies that are rapid and simple to operate. Technologies that do not rely on growth cultures, nucleic acid amplification, step‐wise reagent addition, and complex sample processing are the key for meeting this need. Herein, multiple materials technologies are integrated for overcoming the obstacles in creating rapid and one‐pot bacterial sensing platforms. Liquid‐infused nanoelectrodes are developed for reducing nonspecific binding on the transducer surface; bacterium‐specific RNA‐cleaving DNAzymes are used for bacterial identification; and redox DNA barcodes embedded into DNAzymes are used for binding‐induced electrochemical signal transduction. The resultant single‐step and one‐pot assay demonstrates a limit‐of‐detection of 102 CFU mL−1, with high specificity in identifying Escherichia coli amongst other Gram positive and negative bacteria including Klebsiella pneumoniae, Staphylococcus aureus, and Bacillus subtilis. Additionally, this assay is evaluated for analyzing 31 clinically obtained urine samples, demonstrating a clinical sensitivity of 100% and specify of 100%. When challenging this assay with nine clinical blood cultures, E. coli‐positive and E. coli‐negative samples can be distinguished with a probability of p < 0.001.

“…milk, coffee, cola, and juice) during life are repelled by slippery surfaces and thus can be easily moved with the TCR (figure S8 and movie S7, supporting information). The slippery surface is resistant to corrosion because the lubricant layer can prevent corrosive liquids from effectively contacting the substrate surface [72]. Therefore, the manipulation of corrosive droplets is allowed on slippery surfaces.…”

“Electrostatic tweezer” is a promising tool for droplet manipulation, but it faces many limitations in manipulating droplet on superhydrophobic surfaces. Here, we achieve noncontact and multifunctional droplet manipulation on Nepenthes-inspired lubricated slippery surfaces based on triboelectric electrostatic tweezers (TETs). The TET manipulation of droplets on a slippery surface shows many advantages over the electrostatic droplet manipulation on a superhydrophobic surface. The electrostatic field induces the redistribution of the charges inside the neutral droplet, which makes the triboelectric charged rod drive the droplet to move forward under the electrostatic force. Positively or negatively charged droplets can also be moved by TET based on electrostatic attraction and repulsion. TET enables manipulate droplets under diverse conditions, such as anti-gravity climb, the motion of suspended droplets, corrosive liquids, low-surface-tension liquids (e.g., ethanol with a surface tension of 22.3 mN/m), different droplet volumes (from 100 nL to 0.5 mL), passing through narrow slits, sliding over damaged areas, on various solid substrates, and even droplets in an enclosed system. Various droplet-related applications, such as motion guidance, motion switching, droplet-based microreactions, surface cleaning, surface defogging, liquid sorting, and cell labeling can be easily achieved with TET.

“…SLIPSes are typically developed by injecting a nonvolatile lubricating fluid (often an oil immiscible with water) within the nanotextured surface . Among different oils, silicone oils and vegetable oils have been consistently used as lubricants for infusion into porous structures to develop SLIPS . The oily lubricant, which is wicked into the porous substrate, imparts a high liquid repellency with an extremely low SA .…”

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.
