(a) Percentage release of TP of CC-, BB-, and CC + BB-loaded PLGA NPs over a period of 11 days under conditions resembling the human gastrointestinal tracts. (b) Percent release of TP from BB PLGA NPs (closed circle), CC PLGA NPs (closed square), and CC + BB PLGA NPs (closed triangle) over a period of 28 days in cold storage at 4°C. Data represent mean ± SD (n = 3).
