Integration of biological and nonbiological systems - nanotechnology
Brynda, Eduard
2006 - Czech
The contact of biological media with a synthetic entity starts usually with adsorption of biological macromolecules, particularly proteins, onto its surface and subsequent biological interactions are mediated by a molecular layer formed on the surface. Thus, it is possible to control the interactions by specifically designed artificial assemblies of biological macromolecules immobilized on the object surface prior to its application. Albumin and anticoagulant heparin multilayers are used as blood-compatible coatings, assemblies bearing bioreceptors, such as antibodies and antigens are used as affinity surfaces in biosensors and separation methods. Kontakt biologického prostředí s umělým objektem obvykle začíná adsorpcí biologických makromolekul na jeho objektu a následující biologické interakce jsou zprostředkovány biomolekulární vrstvou utvořenou na povrchu objektu. Tyto interakce tedy můžeme řídit specificky navrženým umělým souborem biologických makromolekul imobilizovaným na povrch objektu ještě před jeho aplikací do biologického prostředí. Vrstvy složené z albuminu a antikoagulantu heparinu jsou využívány jako povlaky snášenlivé s krví, molekulární soubory osahující receptorové molekuly, jako jsou protilátky a antigeny, jsou používány jako afinitní povrchy v biosensorech a separačních metodách.

Structural characterization of chitin/glucan complexes from the mushroom Pleurotus sp. and Aspergillus niger mycelium
Spěváček, Jiří; Synytsya, A.; Brus, Jiří; Ederová, J.; Čopíková, J.
2006 - Czech
Structure and composition of insoluble chitin/glucan complexes isolated from the mushroom Pleurotus spstructure, solid state NMR and Aspergillus niger mycelium were characterized by a combination of solid-state 13C NMR spectroscopy, IR spectroscopy and thermal methods. Kombinací 13C NMR spektroskopie pevného stavu, IČ spektroskopie a termických metod byla charakterizována struktura a složení nerozpustných chitin/glukanových komplexů izolovaných z houby Pleurotus sp. a mycelia Aspergillus niger.

You could not step into the same river twice – rheology of materials
Raab, Miroslav
2006 - Czech
Rheology is typical interdisciplinary science combining chemistry, physics and mechanics. It can be introduced to the program of high schools as an example of cooperation between individual sciences. The lecture gives basic principles of rheology and their application in everyday life. Reologie je typická interdisciplinární věda na rozhraní chemie, fyziky a mechaniky. Mohla by být využita ve výukovém programu středních škol jako ukázka spolupráce různých přírodních věd. Přednáška shrnuje základní principy reologie a jejich projevy v běžném životě.
