“…144 The biwettable principle for drug delivery was demonstrated by Gun'ko and Turov. 145 The authors prepared a hydrophobic hydrogel composed of nanosilica (AM1) and polymethylsiloxane (PMS), while the hydrophilic component was made of A− 300 nanosilica. These were dried and degassed to create nanoparticles that mimic those of medical relevance.…”

Inspired by the Stenocora beetle, selective wettability surfaces incorporate alternating wettable and nonwettable surface features that have received substantial attention over the past two decades. These surfaces are sought after for their very promising potential to drive progress in numerous application fields, including ecological protection, biomedical sciences, and industrial technologies. However, despite ongoing efforts to produce such surfaces in commercial quantities, understanding their basic fabrication concepts for practical applications can be challenging, especially for novices, given the vast technical literature in this area. This review, therefore, aims to elucidate the principles of wettability, along with the evolution of selective wettability surfaces and their uses. Beginning with a summary of the essential history and theory of wetting, we explore naturally occurring surfaces that have influenced wetting studies. We then detail state-of-the-art methods for fabricating these unique biwetting surfaces and show how contemporary science employs such designs in solving realworld problems. Finally, we offer an outlook for future research prospects on scalable, printingbased fabrication methods.

“…Since, the interparticle space in fumed silicas is a system of nanosized cavities, under conditions when most of the pore space remains unoccupied, the embedded substances turn into a system of surface clusters (or domains) that interact with the surface by forming hydrogen bonds, or by the Van der Waals interactions. The properties of substances in a clustered state can differ greatly from those in bulk [13][14][15].…”

The process of water clustering in the interparticle gaps of hydrophilic and hydrophobic silicas in different media was studied using 1H NMR spectroscopy. It has been established that equal amounts of water and oil are introduced into their interparticle gaps under the influence of mechanical load, the water transforms into a nano-sized state. A comparison of the intensities of the signals of water and oil allows us to conclude that the oil is partially frozen in chloroform. In the medium of acetone in the interparticle gaps of hydrophobic silica, the formation of several types of clusters of strongly and weakly associated water is observed, existing as spatially separated nanodroplets. It has been shown that the hydrophobic walls of silica particles have such ordering effect on clusters of water and acetone located in the interparticle gaps that a significant part of acetone turns into a solid state at temperatures (287 К), which is several tens of degrees higher than the bulk freezing temperature.
