Crystallization of ferritin on biocompatible Surfaces – Bare Ti and Ti covered by polypyrrole (PPy)
The purpose of this study was to examine crystallization of ferritin on some biocompatible materials, like bare Ti, and Ti substrate covered by polypyrrole (PPy) through electrochemical polymerization.
Crystallization process is known to be dependent on the way of crystal nucleation – homogenous or heterogeneous. On the other hand, heterogeneous formation of nuclei also depends on the substrate interacting with the crystallizing molecule such reducing the energy of nucleation. Here we report a study of the crystallization of ferritin on bare Ti, Ti covered by polypyrrole (PPy) film through elecropolymerisation, Ti with electrodeposited ferritin on its surface, as well as Ti with ferritin adhered through steeping.
Studies of crystallization have been performed in conditions of vapor diffusion mode, applying hanging and sitting drop versions. Results obtained show that crystallization on a bare Ti surface do not happen for a very long time and crystals become visible after a month, while on a glass surface they are detectable in a week. In case the Ti is covered by ferritin molecules, crystallization happens and crystal morphology depends on the way of ferritin layer has been deposited on the Ti substrate. Crystallization of ferritin on PPy has been found only in case of porous coverage and also mainly in hanging drop experiments.
期刊介绍:
The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
