摘要:
A structure, which has both a drug holding capability and a sustained release ability utilizing a liposome and mechanical strength of a polyhydroxyalkanoate. This structure is excellent in holding capability for hydrophilic drugs and other water-soluble substances, as well as lipophilic drugs and other hydrophobic substances, and is capable of controlling the sustained release ability. The polyhydroxyalkanoate coats at least a part of the outer wall of the liposome.
摘要:
A construct that comprises a base material and a polyhydroxyalkanoate, wherein at least a part of the base material is coated with the polyhydroxyalkanoate, and the polyhydroxyalkanoate comprises a 3-hydroxyalkanoic acid unit other than 3-hydroxypropionic acid unit, 3-hydroxy-n-butyric acid unit, and 3-hydroxy-n-valeric acid unit.In addition, an electrostatic charge image developing toner allows to design the toner characteristics such as chargeability, flowability, stability in time and environmental stability uniform among the toners of different colors. The toner has a small particle size enough for enabling uniform dispersion and being excellent in color saturation and transparency. The toner also shows higher contribution to the environmental security. The toner includes a coloring agent of which at least a part of the surface is covered with polyhydroxyalkanoate (PHA). The toner is produced by dispersing the coloring agent in aqueous medium, then fixing PHA synthesizing enzyme to the coloring agent dispersed in the aqueous medium, then adding 3-hydroxyacyl CoA, and executing a PHA synthesizing reaction to cover at least a part of the surface of the coloring agent with PHA. The toner thus obtained is used for an image forming method.
