通过超声处理层层(LbL)封装与聚阳离子/聚阴离子壳的难溶性材料的水性纳米胶体。同时用超声波破碎粉末颗粒并用聚阳离子涂覆它们的协同作用可以产生直径为150 - 200 nm的聚电解质涂覆的纳米颗粒,具有足够的表面电位以保持胶体稳定性。该技术增加了从抗癌药物到防腐剂、染料和无机盐的低可溶性材料的水溶性。
Aqueous nanocolloids of poorly soluble materials were produced via sonicated layer-by-layer (LbL) encapsulation with polycation / polyanion shells. Synergy of simultaneous breaking powder particles with ultrasonication and coating them with polycations allowed for the production of 150−200 nm diameter polyelectrolyte coated nanoparticles with sufficient surface electrical potential for colloidal stability. This technique increases water dispersibility of low soluble materials ranging from anticancer drugs to anticorrosion agents, dyes and inorganic salts.
