“…This phenomenon is referred as the "lotus effect". [2] Other similar surfaces can be found in butterfly wings, rose petal, rice leaf, and insects' shell as shown in Figure 1a. These surfaces usually have a water contact angle (WCA) larger than 150°a nd a small sliding angle (SA) (usually less than 5°).…”

“…Take lotus leaf as an example, it has a water contact angle as large as 161.0 � 2.7°and a sliding angle as small as approximately 2°, exhibiting superhydrophobic properties. [2] As shown in Fig 3. (a-c), the lotus leaf surface is very rough at the micro and nanoscale. [10] In detail, it has a papillae structure formed with numerous epidermal plant cells at microscale, and at nanoscale with epicuticular wax tubes grown on the surface of the papillae.…”

In recent years, self-cleaning and transparent surfaces have been widely studied for application on smart windows, solar panels, camera lenses, and other optoelectronic devices. The self-cleaning properties can possibly extend the lifetime of these products and decrease, even eliminate, the requirement of chemical detergents and high labor costs of cleaning. It can also promote the overall efficiency of outdoor optoelectronic devices (e. g. solar cell panels) since dirt accumulation and bacteria growth can be slowed down, even inhibited on such surfaces. In this mini review, the fundamentals and conditions that govern superhydrophobicity and transparency are introduced, followed by the discussion of roughness as the competing factor for superhydrophobicity and transparency. Representative examples of the surface design and fabrication are introduced and future perspectives are shared. This mini review can help the research community better understand such surfaces and further accelerate its development for innovative practical applications.

“…Unfortunately, these stabilities cannot last too long and after a large cycle value, the hydrophobicity will still decrease. Wang et al 141 constructed a superhydrophobic surface with an armored structure through a hierarchical scale. The superhydrophobicity was provided by the nanostructure and the microstructure provided the robustness.…”

Inspired by nature, scientists and researchers have studied the wetting behaviors on various creatures and mimicked their structures to fabricate diverse functional superwetting materials. As one kind of emerging application, the bioinspired superwettable surfaces used for biosensing have been aroused wide interests. In this review, we summarized the recent developments of bioinspired superwettable surfaces in the field of biosensing. In the first part, superwettable creatures in nature, namely, superhydrophobic self-cleaning lotus leaf, high-adhesion superhydrophobic rose petal, amphiphobic springtail, patterned wetting desert beetles, slippery pitcher plant, were introduced. In sequence, we successively described the special wetting models of superhydrophobicity, superamphiphobicity, responsive wettability, patterned wettability, and slipperiness. Then, biosensing applications based on the respective patterned wettable, superhydrophobic, responsive wettable, and slippery substrates that were combined with the common detection approaches (colorimetry, fluorescence, surface-enhanced Raman scattering (SERS), electrochemistry) were shown in detailed. At last, an insight of remaining challenges and future development for bioinspired superwetting materials applied in biosensing was provided.
