“…Transitioning from the plant to the animal kingdom, it is important to state that apart from "slippery" surfaces discussed above, "adherent" superhydrophobic surfaces were also noted: the gecko lizard's finger structures confer them the ability to climb even perfectly vertical walls, due to micrometric lamellae divided into nanometric setae. A drop placed on this surface retains its shape even in an antigravity position [23,24]. The gecko feet model inspired climbing a glass building using Kevlar and polyurethane special gloves [25].…”

With the help of biomimetics, superficial characteristics were transposed, through various methods, onto artificially obtained materials. Many industrial fields applied surface architecture modifications as improvements of classic materials/methods. The medico-pharmaceutical, biochemical, transportation, and textile fields are few examples of industrial areas welcoming a "structural change." Antibioadhesion was widely exploited by means of antibacterial or self-cleaning fabrics and cell culturing/screening/isolation. Anti-icing, antireflective, and anticorrosion materials/coatings gained attention in the transportation and optical device fields. Interdisciplinary approaches on extreme wettability include "solid-fluid" formations called liquid marbles, which will be further discussed as a superhydrophobic behavior exponent.

“…given by Adhesion F = K 2πr (4) r = R sinθ (5) wWhere, r is the radius of the contact zone of water droplet on the surface, R is the radius of curvature of water droplet sitting on the solid surface and K is the interfacial energy with units of force/area (N/m). The interfacial energy is dependent on the chemical nature of the solid-vapour interface.…”

“…Interestingly, this trait of superydrophoicity can be applied to self-cleaning process, which roots from the water repellent behaviour of naturally occurring lotus leaves This phenomenon of self-cleaning property is inspired from the naturally occurring water repellent behaviour of lotus leaves [1][2][3][4][5][6]. Self-cleaning effect based on superhydrophobicity is can be defined as the water droplet aided removal of dust particles removal of dust particles by the water droplet at a small tilt angle of the high water contact angle surfaces [7][8][9][10][11][12].…”

A ZnO nanorods based superhydrophobic surface with extremely low roll-off values is fabricated using a two-step solution based approach-Successive Ionic Layer Adsorption and Reaction (SILAR) and Chemical Bath Deposition (CBD). The grown ZnO nanorods have average diameter of 285 nm with a predominant growth direction of [002]. The static contact angle of ZnO nanorods superhydrophobic surface is 155°, and the dynamic contact angles such as contact angle hysteresis and roll-off angle is 2° and 1° respectively. Furthermore, to comprehend the mechanism governing the extremely low roll-off angle of ZnO nanorods based superhydrophobic surface, Aan analytical model has been developed by incorporating the topographical (diameter, density of nanorods and solid area fraction) and droplet parameters (surface tension, mass and volume) to understand the mechanism associated with the extremely low roll-off angle of ZnO nanorods based superhydrophobic surface. The theoretically calculated roll-off angle closely matches with the experimental results and other reported results reported in the literature.

“…[19,20] However, the surface coating of gold nanoparticles and nanorods to improve their biocompatibility would weaken the therapeutic efficacy. [21,22] Polymers with photochromic groups, which was induced by light to change the architectures, have been exploited as light-sensitive polymers. [23] The wavelength of light to trigger the reversible photoisomerization or irreversible photocleavage of light sensitive polymers was located in the region of UV or visible light.…”

A near infrared (NIR) light responsive chromophore 7-(diethylamino)-4-(hydroxymethyl)-2H-chromen-2-one (DEACM) was synthesized and incorporated to β-cyclodextrins with cRGD functionalized poly(ethylene glycol), the amphiphiles were coordinated with Au nanorods or nanoparticles to load anticancer drug doxorubicin (DOX) for fabricating hybrid nanoparticles. The π-π stacking interaction between DEACM and DOX was formed in the hybrid nanoparticles, which contributed to the high drug loading content. The Au nanorods or nanoparticles enhanced the photosolvolysis of DEACM under the irradiation of NIR with 808 nm wavelength and triggered the accelerated drug release from the nanoparticles. The drug loaded hybrid nanoparticles with NIR irradiation exhibited efficient inhibition effect on the proliferation of 4T1 breast cancer cells in vitro. The in vivo anticancer activity study on breast cancer bearing mice revealed that the hybrid nanoparticles containing Au nanorods exhibited excellent anticancer activity under the irradiation of 808 nm wavelength NIR with 800 mW.
