对用于表面等离子体极化激元(SPP)生物传感器的自立式CyTOP薄膜进行了机械膨胀测试。将实验数据与已知的挠度模型进行曲线拟合，得到的杨氏模数为1.3+/-0.1 GPA，残余应力为16.9+/-1.3兆帕。膜的断裂应力为96.9+/-8.4 Mpa，发生在膜的边缘。
Mechanical bulge testing of thin free-standing CYTOP membranes for use with surface plasmon polariton (SPP) biosensors was conducted. Curve fitting of experimental data to a known deflection model allowed for the extraction of a Young's modulus of 1.3 +/- 0.1 GPa and residual stress of 16.9 +/- 1.3 MPa. The fracture stress for the membranes was observed to be 96.9 +/- 8.4 MPa, which occurs at the membrane edges.
