Title:
SOLUBLE TABLET CONTAINING NANOSILICON PARTICLES AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/026533
Kind Code:
A1
Abstract:
Disclosed is a tablet comprising a sodium chloride powder and an abundance of
nanosilicon particles having a particle size in the range of 1.5 to 2.0 nm, 2.0
to 2.5 nm or 2.5 to 3.5 nm blended into the powder, which can emit a fluorescent light
with blue, green or red color in the blood upon being irradiated with ultraviolet
ray or visible light. The tablet can be produced by immersing nanosilicon particles
in a mixed solution containing a therapeutic agent and a polymeric compound such
as a polysaccharide or protein, subjecting the resulting mixture to a thermal
treatment and then mixing the resulting product with a sodium chloride powder.
