一般說明

Pluronic® F108 是三嵌段共聚物和末端伯二羟基官能低聚物。它表现为非离子表面活性剂。它是表面活性材料，其性质取决于亲水（EO）/疏水（PO）比。高 EO 含量可提供更好的 o/w 稳定剂。

應用

Pluronic® F108 在培养基中用作表面活性剂，以防止细胞粘附到微流体装置的表面。{7}-{11} Pluronic 可能是有用的病原体检测器。它被用于分析微生物群落和基因分型单核苷酸多态性（SNPs）。{9}三嵌段共聚物被用作孔模板，用于制造多孔碳和碳/二氧化硅复合材料。{10}
软硬表面清洁剂、涂料和水处理中的消泡剂。金属加工润滑剂，线性和交联聚酯及聚氨酯的消泡助剂和增量剂。

特點和優勢

性质取决于亲水性 (EO)/疏水性 (PO) 比例的表面活性物质EO 含量越高，水包油稳定剂性能越好。

外觀

末端主要是二羟基官能化低聚物。

Understanding how forces orchestrate tissue formation requires technologies to map internal tissue stress at cellular length scales. Here, we develop ultrasoft mechanosensors that visibly deform under less than 10 Pascals of cell-generated stress. By incorporating these mechanosensors into multicellular spheroids
