  • Descrição: [Display omitted] •Arsenic trioxide-nanoliposome encapsulates were synthesized.•Stability of arsenic trioxide encapsulates with liposome was evaluated.•Stability of As(III) depends on the storing conditions.•Arsenic species were monitored by LC-ICP-MS during 90-days. In this work, we investigated the stability of arsenic trioxide (ATO) used in leukemia treatment, encapsulated with nanoliposome, with the aid of ultrasound treatment. Stability studies of As species were followed by liquid chromatography-inductively coupled plasma mass spectrometry (LC-ICP-MS), allowing for the detection of the conversion of low amounts of As(III) to As(V) or the formation of other As species. The influence of storage temperature and time on ATO was evaluated. Low amounts of As(III) to As(V) conversions were observed when the As encapsulated with nanoliposome was incubated at 25 °C and 40 °C. However, As(III) was stable if the solution was maintained at 5 °C,...
