柠檬醛作用下黄曲霉细胞膜的多力学参数测定

Measurement of Aflatoxins Membrane Mechanics Characteristic Multi-parameter Under the Influence of Citral

在无扰、在位、实时的情况下,测量了黄曲霉细胞膜的力学参量:弯曲模量Kc、剪切模量μ及表征切向与弯曲模量之比ε。对不同柠檬醛浓度作用下黄曲霉细胞各力学参量进行了连续动态检测。结果表明,柠檬醛浓度的提高黄曲霉素细胞的变形能力逐渐减弱,提示出柠檬醛对黄曲霉素细胞膜的破坏作用。

The purpose of this paper is to develop a new dynamic image analyzing technique with the ability of performing non - invasive, in situ, real time measurement on viscoelastic parameters of single intact aflatoxins cell membrane. With these technique, the bending modulus Kc, shear elasticity μand ε, the ratio of shear and bending elasticity have been measured as functions under the influence of citral.
