HOLLOW SPONGE SPICULE, AND PREPARATION METHOD THEREFOR AND USE THEREOF

A hollow sponge spicule, and a preparation method therefor and a use thereof. Specifically disclosed are a preparation method for a hollow sponge spicule using a sponge Haliclona sp. spicule and the like as basic raw materials, and characterization data after treatment with the preparation method. According to the preparation method, an alkaline solution prepared from sodium hydroxide is used as a treating agent, and a sponge spicule is soaked and shaken, so as to achieve the purpose of reacting the alkaline solution with a silicon substance contained in the spicule, thereby generating a hollow channel in the spicule. Thus, the efficiency of transdermal drug delivery is improved, the drug utilization rate is improved, and more efficient, stable and safe transdermal absorption of a series of biomacromolecules such as drugs and cosmetic active components is promoted. L'invention concerne un spicule d'éponge creux, et son procédé de préparation et son utilisation. L'invention concerne spécifiquement un procédé d
