Investigation on microstructure and wettability of mosquito's body surface

Wettability of mosquito's body surface (such as wings and eyes) was investigated by means of optical microscopy and self-design system and contact angle meter system. The anti-fogging properties on mosquito's eye and water-repellency of wings are mainly observed. It is found that there are different topographies of microstructures at different parts of mosquito's body surfaces such as wings and eyes observed by environmental scanning electron microscopy. It reveals the important relation of surface microstructure and biological adapted wettability, and is helpful to the biomimetic research in material preparation or surface design for functional interfaces.
