Dry amorphization mechanically activated by milling equilibrium between AP mesoporous silica

摘要

PROBLEM TO BE SOLVED: To provide particles, a method for producing and using particles suitable for use as a delivery agent for an active ingredient (for example, a drug) in various processes not limited to drug delivery. SOLUTION: (a) porous silica particles, (b) at least one particulate active component mechanically incorporated into the pores of the porous silica particles, and (c) the total of the composite particles. By specific composite particles consisting of 0-5.0% by weight of water relative to weight. [Selection diagram] None
