摘      要：The wing architecture is an inspiration to fabricate novel materials with exquisite *** current study characterizes the structure and biological function of a termite’s *** topography of the surface of the wing was studied by electron microscopy,and surface *** physicochemical property of the surface was analyzed by Fourier transform infrared spectroscopy,X-ray diffraction spectroscopy,energy-dispersive X-ray spectroscopy,and gas chromatography-mass spectrometry analysis of the epicuticle *** Contact Angle measurement confirmed the hydrophobicity of the wing *** microorganisms come in contact with the surface of the wing,they adhere to the wing surface due to cell surface properties of their own and the surface chemistry of the *** current study reported the adhesion behavior of two bacterial *** bactericidal activity of the wing was confirmed by counting the bacterial cell viability and examination under a confocal laser scanning *** of bacteria was observed under the electron *** oxidative stress,the topography of the wing,and the surface chemistry of the wing are the crucial factors that induce bactericidal *** nanostructure along with the chemical composition of the wing can be mimicked for the fabrication of novel material with antibacterial properties.
