PRODUCTION METHOD OF NANO FLUID DISPERSION, AND NANO FLUID DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing efficiently a nano fluid dispersion having improved maintainability, concerning a nano fluid dispersion of a slightly-soluble material such as curcumin and its kind.SOLUTION: In a production method of a nano fluid dispersion, a target 1 containing a slightly-soluble material 3 is irradiated with an ultrashort pulse laser beam 23 having a pulse time width of 1 fsec to less than 200 psec to perform laser ablation, in a liquid medium 2 containing host molecules 4 such as a cyclodextrin-based compound, capable of forming an inclusion complex 5 of the slightly-soluble material 3.SELECTED DRAWING: Figure 1
