Shape deformation and phase separation dynamics of two-component vesicles.
Biological vesicles exhibit a wide variety of shape transformations by the change of their environment such as temperature, pH, osmotic pressure and so forth. Such transformation has been fascinating a lot of scientists. After the pioneering works by Canham and Helfrich, many researchers have investigated theoretically and experimentally in depth membrane systems and make clear shape deformatio...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Shape Deformation of Vesicle Coupled with Phase Separation
One of the most fascinating properties of lipid membranes is that they easily deform their shapes according to external circumstances, which gives them the basic physical aspects of biomembrane functionalities such as endocytosis and exocytosis in biomembrane transport. These shape deformations well described by an area-difference free energy (ADE) model [1], which consists of two terms, the He...
متن کاملShape deformation of ternary vesicles coupled with phase separation.
We report an experimental study on shape deformations of ternary vesicles undergoing phase separation under an osmotic pressure difference. The phase separation on various shape vesicles causes unique shape-deformation branches. In the domain coarsening stage, prolate, discocyte, and starfish vesicles show a shape convergence to discocytes, whereas a pearling instability is observed in tube ves...
متن کاملPhase separation in lipid membranes.
Cell membranes show complex behavior, in part because of the large number of different components that interact with each other in different ways. One aspect of this complex behavior is lateral organization of components on a range of spatial scales. We found that lipid-only mixtures can model the range of size scales, from approximately 2 nm up to microns. Furthermore, the size of compositiona...
