Abstract

The new experimental results and theoretical approaches in the bioferroelectricity field are analyzed and discussed. The earlier predicted Ferroelectric and Liquid-Crystal-Like Ferroelectric properties of a biological membrane (V. Bystrov, Ferr.Lett., 1992, v.13(6), p.127; 1997, v.27., p.87; 2000, v.27(5-6), p.147; R.Leuchtag&v.Bystrov, Ferroelectrics, 1999, v.220(3-4), p. 157), which was studied in the ion channels, now was experimentally observed in bacteriorhodopsin containing purple membrane films (I.Ermolina et al, J.Phys.Chem., 2001, v.105 (14), p. 2673). Recently bioferroelectric properties of biological objects had developed to the biomedical applications. One of this specific features is the nonlinear response on the weak actions (irradiation, external fields, various kind of nutrition etc.) in the vicinity of the critical for human organism (bifurcation) point, characterized biological object on various levels as on molecular, cell as on the whole organism level.

生物电学与生物医学:新成果与新方法

分析和讨论了生物热发电领域新的实验结果和理论方法。先前预测的生物膜的铁电特性和液晶样铁电特性(V. Bystrov, Ferr.Lett)。， 1992年，第13(6)节，第127页;1997年,v.27。p.87;2000，第27节(5-6)，第147页;R.Leuchtag&v。Bystrov, Ferroelectrics, 1999, v.220(3-4)， p. 157)，在离子通道中进行了研究，现在在含有紫色膜膜的细菌视紫红质中进行了实验观察(I.Ermolina et al .， J.Phys.Chem)。， 2001，第105页(14)，第2673页。近年来，生物物体的生物热电特性已发展到生物医学领域。这种特殊的特征之一是对人体有机体临界(分岔)点附近的弱作用(辐照、外场、各种营养等)的非线性响应，在分子、细胞以至整个生物体的各个水平上表征生物对象。
