| Outline of Final Research Achievements |
In this study, metal nanoballs were applied as the resource of metal allergy patch test and the metal ion release and permeation into skin were estimated.
Ni and other metal nanoballs were dispersed in the mildly acidic solution and the enough ion release through the dialysis membrane was confirmed. Also, continuous ion permeation into skin with same method was estimated with the synchrotron radiation X-ray fluorescence. The permeation occurred in lower concentration with time dependently compared to conventional patch test.
In conclusion, the metal nanoballs was suggested to be applicable as the resource of metal allergy patch test.
