Biological surfactants connected to surfaces of silicone-based materials are provided. Compositions of electrolytes and a biological surfactant are also provided. Methods for increasing the surface wettability of a silicone-based material by contacting the silicone-based material with a biological surfactant, methods for increasing evaporation from a silicone-based material by contacting a surface of the silicone-based material with a biological surfactant, methods for increasing levels of interleukin-8 during inflammation by contacting a cell with a biological surfactant, and methods for decreasing expression of a biological surfactant by contacting a cell with an siRNA are further provided.
