Measurement of increased uptake of osmium in skin and in a gelatin model 'tissue' treated with tannic acid.
The effect of tannic acid (TA) on the deposition of osmium was studied in discs of hamster skin and in fixed gelatin. Pieces of skin treated with 1.0% TA before OsO4 fixation absorbed almost twice as much as untreated pieces. Gelatin, used here as a model 'tissue' showed an even greater degree of enhancement. Treated gelatin capsule halves and strips took up 4-6 times as much osmium as untreated ones. The deposition of osmium was verified by neutron activation analysis.
