Evaluation of the Antimicrobial Activity of Nanostructured Materials of Titanium Dioxide Doped with Silver and/or Copper and Their Effects on Arabidopsis thaliana

Table 1

Treatments of exposition of A. thaliana to NSM.

Treatment	A. thaliana	Exposure medium	Exposure time	Parameter
1	Seeds	H2O distilled	24 h	Germination and development
		Phosphate buffer pH 5.7
2	Seeds-seedlings	H2O distilled	1 week	Elongation of seedling
		MS liquid
3	Two-day-old seedlings	H2O distilled	24 h	Elongation of seedling

Exposure media were supplemented with 0, 0.5, 1, 2.5, 5, and 10 mg/mL of NSM (Ag@TiO₂ or TiO₂-Cu²⁺), 0.015 mM Ag⁰, or 1 mM CuSO₄.
