“…Evidence shows that the above-illustrated etching methods make it challenging to prepare surface structures with desired geometric order and well-defined shapes (e.g., subwavelength structures, SWSs). In this context, reactive ion etching (RIE) has proven to be a more suitable approach due to its unique ability to etch with finer resolution, and higher aspect ratio than isotropic etching does [235]. For example, Lee and colleagues [236] tailored the wettability of borosilicate glass substrates by means of a self-masked RIE operating under controlled conditions, namely, 50 W and CF4:O2 ratio of 4:1.…”

Glass-and polymer-based materials have become essential in the fabrication of a multitude of elements, including eyeglasses, automobile windshields, bathroom mirrors, greenhouses, and food packages, which unfortunately mist up under typical operating conditions. Far from being an innocuous phenomenon, the formation of minute water drops on the surface is detrimental to their optical properties (e.g., light-transmitting capability) and, in many cases, results in esthetical, hygienic, and safety concerns. In this context, it is therefore not surprising that research in the field of fog-resistant surfaces is gaining in popularity, particularly in recent years, in view of the growing number of studies focusing on this topic. This review addresses the most relevant advances released thus far on anti-fogging surfaces, with a particular focus on coating deposition, surface micro/nanostructuring, and surface functionalization. A brief explanation of how surfaces fog up and the main issues of interest linked to fogging phenomenon, including common problems, anti-fogging strategies, and wetting states are first presented. Anti-fogging mechanisms are then discussed in terms of the morphology of water drops, continuing with a description of the main fabrication techniques toward anti-fogging property. This review concludes with the current and the future perspectives on the utility of anti-fogging surfaces for several applications and some remaining challenges in this field.

“…Inspired by this biological mechanism, Han et al constructed a superhydrophilic surface with nanopillars to prevent the formation of biofilms on medical devices. [215] The proposed superwettable surface demonstrated excellent killing ability on Gram-negative bacterial species such as Pseudomonas aeruginosa (P. aeruginosa) and E. coli, as shown in Figure 13e. More importantly, the nanopillar-structured superhydrophilic surface also displayed favorable antifogging and antireflective performances, which made it ideal for constructing optical devices in medical field.…”

“…To solve these, researchers have dedicated to developing biomaterials with specific wettability, together with adding antibacterial ingredients for further treatment. Up to date, medical dressings based on biomaterials with specific wettability have demonstrated values in accelerating the wound healing process through removing excessive biofluid around wounds, [ 96 , 174 ] inhibiting adhesion of harmful biomolecules, [ 174 , 175 , 176 , 177 , 178 , 179 , 180 , 181 , 182 , 183 , 184 , 185 , 186 , 187 , 188 , 189 , 190 , 191 , 192 , 193 , 194 , 195 , 196 , 197 , 198 , 199 , 200 , 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 ,…”

“…Bacterial deposition on optical devices like endoscopic devices, microscopic slides, and contact lenses has brought extensive concern in the hygiene problems of biomedical optical devices. Han et al [ 69 ] presented the first hydrophilic transparent nanopillar-structured surface with bactericidal property on a quartz substrate via nanosphere lithography, and the anti-fogging and anti-reflective properties were also probed in the research. Two typical Gram-negative bacteria ( P. aeruginosa and E. coli ) associated with various eye diseases were selectively incubated on the fabricated nanopillars, and the highest bactericidal efficiency was observed in the test on nanopillars that were 300 nm in height and 10 nm in apex diameter.…”

The surface with high-aspect-ratio nanostructure is observed to possess the bactericidal properties, where the physical interaction between high-aspect-ratio nanostructure could exert sufficient pressure on the cell membrane eventually lead to cell lysis. Recent studies in the interaction mechanism and reverse engineering have transferred the bactericidal capability to artificial surface, but the biomimetic surfaces mimicking the topographical patterns on natural resources possess different geometrical parameters and surface properties. The review attempts to highlight the recent progress in bactericidal nanostructured surfaces to analyze the prominent influence factors and cell rupture mechanism. A holistic approach was utilized, integrating interaction mechanisms, material characterization, and fabrication techniques to establish inclusive insights into the topographical effect and mechano-bactericidal applications. The experimental work presented in the hydrogel material field provides support for the feasibility of potentially broadening applications in soft contact lenses.
