Abstract: An object is to provide a composite plating film excellent in the water-repellent property and oil-repellent property using a material that is less likely to accumulate in the environment, as substitute for a fluorine resin. A composite plating film is provided which includes an alloy matrix phase and a silicone dispersed in the alloy matrix phase. In the composite plating film, the silicone preferably has Hansen solubility parameters comprising a dispersion term ?D of 15 MPa1/2 or less, a polar term ?P of 3 MPa1/2 or less, and a hydrogen bonding term ?H of 3 MPa1/2 or less. The silicone preferably has an interaction radius of a Hansen solubility sphere of 5.0 MPa1/2 or less.

Abstract: An object of the present invention is to provide a biocompatible liquid that is more essential and practical, and a method for screening the same. The object is achieved by using, as the biocompatible liquid, a liquid having a Hansen solubility parameter (HSP) compatible to a cell to which the liquid is applied.
