Optické metody studia adsorpce fibrinogenu a oligodeoxynukleotidů na povrchu titanu a titanových slitin.

Adsorpce fibrinogenu na povrch titanu hraje významnou roli při oseointehraci titanových implantátů. Adsorpce je ovlivněna fyzikálními vlastnostmi povrchu titanu.Adsorpce fibrinogenu na povrch titanu hraje významnou roli při oseointehraci titanových implantátů.

Adsorption of fibrinogen at the titanium depends on the physical properties of the titanium surface

Effect of Thymine and Cytosine Nucleobase Sequence on the Two-Dimensional Condensation of Pyrimidine Oligodeoxynucleotides at Mercury Surface

The aim of this contribution is study the effect of thymine and cytosine nucleobase composition (different lengths and/or repeat segments of either thymine or cytosine units or their combinations) within a set of the oligodeoxynucleotide (ODN) chains on the two-dimensional of homo- and hetero-pyrimidine ODNs at mercury electrode surface. It was shown that pyrimidine ODNs containing eight and more pyrimidine nucleobases can form, at negatively charged Hg surface (around1.32 V vs. Ag/AgCl), two different 2D condensed films characterized by the differential capacitances of about 9.4 (I-2D) and 7.6 mu F cm(-2) (II2D) respectively

Voltammetric Detection of Purine Nucleobases on Screen-Printed Graphite Electrodes Modified by Nanocarbon Materials

Recent studies have shown that the electrochemical oxidation of purine nucleobases (adenine and geaoine) at graphite electrodes is strongly dependent on the orientation of graphene sheets. their size and mutual distribution on the electrode surface. Edges and defects of graphene sheets affect the kinetics of oxidation processes, basal planes support the adsorption processes The aim of this study is to determine how model carbon nanomaterials including graphene, single-walled or multi-wailed carbon nanotubes. carbon nanofibres and mesoporous graphene affect the electrochemical oxidation or purine nuclebases on screen-printed carbon electrodes modified by these nanostructures in solution without and in the presence of copper
