The occurrence of air-trapping inside poly-eta-caprolactone nanopits was investigated by measuring the contact angles of water droplets on a set of defined nanotopographies. It is shown that the advancing angles follow the Cassie-Baxter theory, thus revealing the presence of air bubbles inside the biodegradable nanopatterns. The importance of these observations for the definition of hydrophilicity/hydrophobicity and in the context of in vitro cell behavior is discussed.
通过测量一组定义好的纳米形貌上水滴的接触角，研究了聚-η-己内酯纳米凹坑内空气截留的情况。结果表明，前进角遵循卡西-巴克斯特理论，从而揭示了可生物降解纳米图案内气泡的存在。讨论了这些观察结果对于定义亲水性/疏水性以及在体外细胞行为背景下的重要性。
