Influence of suspending agents on (a) the appearance and (b) particle size and homogeneity of DTS-NS formulas prepared using a lab-scale bead-milling technology. Notes: (a) All images were captured on glass slides within 10 min after fabrication (scale bar: 5 mm). (b) The concentrations of DTS and suspending agent were fixed at 40 mg/mL and 5 mg/mL, respectively. Bead milling was carried out at 1500 rpm for 1 h under conditions of −10 °C. Data represent means ± SD (n = 3).
