Abstract
Polypeptide particles of the present invention are particles of a polypeptide derived from spider silk proteins, and have an average particle size of 1000 nm or less. A method for producing polypeptide particles of the present invention includes: a solution production step in which the polypeptide is dissolved in at least one solvent selected from the group consisting of DMSO, DMF, and these with an inorganic salt, so as to obtain a solution of the polypeptide; a step in which the solution produced in the solution production step is substituted with a water-soluble solvent so as to obtain an aqueous solution of the polypeptide; and a step in which the aqueous solution of the polypeptide is dried. Thereby, the present invention provides polypeptide particles suitable for application to a living body and capable of being applied to cosmetics, etc., while identifying the properties of the polypeptide particles, and a method for producing the same.
