Title:
DRUG SUSTAINED RELEASE AGENT, ADSORBENT, FUNCTIONAL FOOD, MASK, AND ADSORPTIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2010/018855
Kind Code:
A1
Abstract:
Provided is a drug sustained release agent comprising a carbon material (porous carbon material) having an inverted opal structure. The drug sustained release agent comprises a porous carbon material having a surface area of 3 x 102 m2/gram or greater wherein spherical pores having an average diameter of 1 x 10-9 m to 1 x 10-5 m are three-dimensionally arranged; a porous carbon material wherein pores are visibly arranged in a pattern corresponding to a crystal structure; or a porous carbon material wherein pores are visibly arranged at the surface of a pattern corresponding to the (111) face orientation of a face-centered cubic structure.
