树突状细胞（DC）疫苗是目前在临床上应用的一种肿瘤治疗疫苗，其制备过程一般都在病人体外进行，病人来源的DC在体外进行诱导分化后再回输给病人，这种疫苗制备过程十分复杂，容易被污染，不同的技术人员、不同条件的实验室制备的疫苗疗效差异较大，较难标准化，因此体外制备的DC疫苗很难在临床推广应用。
以三羟甲基丙烷三丙烯酸酯（TMPTA）和1-十二烯（DC）为单体，不使用任何乳化剂或分散稳定剂，通过沉淀聚合制备了高度单分散P（DC-TMPTA）的聚合物微球颗粒.以此聚合物微粒为Pickering稳定剂，不添加任何化学助剂，以乙醇-水混合介质在70℃下通过恒速振荡制得了单分散石蜡Pickering乳液.将该体系迅速降温至石蜡熔点之下，制得了窄分布的固体石蜡微球.研究了连续相水含量、振荡频率及稳定...
