A hydrophilic active molecule delivery system whereby active molecules can be released on demand and/or a variety of different active molecules can be delivered from the same system and/or different concentrations of active molecules can be delivered from the same system. The system may be used to deliver/release hydrophilic active ingredients, generally.一種親水性活性分子遞送系統，藉此可應需求釋放出活性分子，及/或可從相同系統遞送多種不同的活性分子，及/或可從相同系統遞送不同濃度的活性分子。該系統通常可使用來遞送/釋放親水性活性成份。
