一种方便技术为为细胞的粘附测量极其软的材料的有弹性的模量在这笔记被报导。在严肃下面把柱体弄弯的标本被用来避免在严峻的设备和样品之间的接触问题,并且一个横梁模型为与大有弹性的变丑评估胶化横梁的弯曲被介绍。一个自我适应的算法也被建议由把试验性的弯曲弯曲与那些与 preestimated moduli 从横梁模型计算了作比较寻找胶化的有弹性的 moduli 的最好的评价。到 polyacrylamide 胶化的性质的测量的申请显示材料依从与 bis-acrylamide,和胶化的集中变化在为时间的一个时期沉浸于文化媒介以后变得更软,不管到到什么程度,他们是 polymerized。
A convenient technique is reported in this note for measuring elastic modulus of extremely soft material for cellular adhesion. Specimens of bending cylinder under gravity are used to avoid contact problem between testing device and sample, and a beam model is presented for evaluating the curvatures of gel beams with large elastic deformation. A self-adaptive algorithm is also proposed to search for the best estimation of gels' elastic moduli by comparing the experimental bending curvatures with those computed from the beam model with preestimated moduli. Application to the measurement of the property of polyacrylamide gels indi- cates that the material compliance varies with the concentrations of bis-acrylamide, and the gels become softer after being immersed in a culture medium for a period of time, no matter to what extent they are polymerized.
