Magnesium acetate tetrahydrate

Zinc acetate dihydrate [Zn(CH₃COO)₂.2H₂O, Merck & Co., Inc., Kenilworth, NJ, USA], and magnesium acetate tetrahydrate [Mg(CH₃COO)₂.4H₂O, Alfa Aesar, Haverhill, MA, USA] were used as precursors without purification. HPLC grade methanol (Merck & Co., Inc.) and monoethanolamine (Merck & Co., Inc.) were used as solvent and sol stabilizer respectively. Tyriptic soy agar (TSA) and tyriptic soy broth (TSB) were purchased from Merck & Co., Inc. Distilled deionized water (DDW) was obtained from a Human Zeneer power 1 water purification system (Human Corporation, Seoul, Korea). Phosphate buffer solution (PBS, pH 7.35) for hemolysis tests was prepared using NaCl (8 g/L), KCl (0.2 g/L), Na₂HPO₄.2H₂O (1.78 g/L) and KH₂PO₄ (0.24 g/L) andsterilized by autoclaving at 1 atm and 121 o C for 15 min. MeB (Methylene Blue - C₁₆H₁₈N₃ClS.3H₂O) was used as model organic dye in photocatalytic activity measurements.

Cadmium oxide (CdO, 99.99%), selenium (Se, −200 mesh, 99.999%), zinc acetate (Zn(ac)₂, 99.99%), sulfur (S, 99%), oleic acid (OA, 90%), 1-octadecene (ODE, 90%), tri-n-octylphosphine (TOP, 97%), magnesium acetate tetrahydrate ((CH₃COO)₂Mg·4 H₂O, 99.997%) and 2-methoxyethanol (CH₃OCH₃CH₃OH, 99.3%) were purchased from Alfa Aesar. Ethanolamine (99.5%), Poly(amidoamine)dendrimers (PAD), methanol (99.8%) and toluene (99.8%) were purchased from Sigma Aldrich. Tris(4-carbazoyl-9-ylphenyl)amine (TCTA, 99.5%) was purchased from Lumtec. All chemicals were used as is without additional purification.
