Istraživanje interakcije dejonizovane vode sa hidrofilnim i hidrofobnim materijalima, biomolekulima i hidrogenizovanim ugljeničnim nanomaterijalima

Abstract

Predmet i cilj istraživanja ove doktorske disertcije je utvrđivanje postojanja interakcije između dejonizovane vode (18,2 MΩ) i različitih tipova materijala: hidrofobni i hidrofilni materijali, biomolekuli, hidrogenizovani ugljenični nanomaterijali. Da bi se ovaj cilj realzovao izvršene su četiri različite vrste eksperimenta u kojima su korišćene različite koncentracije rastvorenih ispitivanih supstanci, pri čemu su sve promene posmatrane putem mikroskopije sa velikim uvećanjima i rezolucijom, a podaci obrađivani kompjuterskim softverom. Istražujući interakcije dejonizovane vode objašnjen je fenomen eksluzivne zone sa aspekta vodoničnih veza, potvrđen je fenomen postojanja eksluzivne zone koji se može snimiti mikroskopom na osnovu migracije mikrosfera prečnika 1 μm u vodenim rastvorima, utvrđeno je da veličina eksluzivne zone zavisi od koncentracije mikrosfera u rastvoru, da se u kontaktu hidrogenizovanih ugljeničnih nanomaterijala i hidrofobnog materijala stvara zona vode sa drugačijim karakteristikama i da se pored sočiva kao hidrofilne membrane u dodiru sa hidrofilnim mikrosferama formiraju eksluzivne zone. Prvi put je posmatran fenomen struktuiranja i stvaranje uređenih slojeva pri interagovanju hidrogenizovanog ugljeničnog nanomaterijala fulerola, hidrofilnih čestica mikrosfera i hidrofobnog materijala nafiona. Fenomen stvaranja eksluzivne zone ima višestruke primene i značaj u ispitivanju biološkog sveta, pa se tako koristi u procesima predfiltriranja vode, biomedicini pri stvaranju suznog filma i nanofluidici pri stvaranju transportnih i procesnih elemenata na nano-nivou. Izvršena istraživanja će imati uticaj na razvoj „water based nanomedicine“ oblasti biomedicinskog inženjerstva uz primenu biokompatibilnih nanomaterijala.

Subject and the goal of this doctoral disertation is determination of appereance and existance of the interaction between deionized water (18,2 MΩ) and different types of materials: hydrphobic and hydrofilc materials, biomolecules, hydrogenized carbon nanomaterials. To realize this goal there were conducted four exeriments in which are used different concentrations of diluted examined substances, all changes are observed with high resolution microscopy, and datas are elaborated with computer softvare. By examining the interaction of deionized water it is explained phenomena of exclusion zone from the aspect of the hydrogen bonds, it is cofirmed the phenomena of exclusion zone which can be observed and recorded with mcroscope based on migration of microspheres whose diameter is 1 μm in water solutions, it is determined that size of the exclusion zone depends of the concentration of microspheres in the solution, that in contact of hydrogenized carbon nanomaterials and hydrphobic material forms area of water with different properties, and that next to the contact lens as hydrphlici membrane in contact with hydrophilic microspheres exclusion zone is forming. For the first time is examined and observed the appereance of structuring layers in interaction of hydrogenized carbon nanomaterial fullerol, hydrophobhilic particles microspheres, and hydrophobic material nafion. Phenomena of exclusion zone have multiple implementations and significance in examination of biological systems, so it can be used in processes of prefiltration of water, biomedicine of making tear film, and nanofluidics in making the transport and process elements on nano-level. Experminets that have been done will have the impat on development of „water based nanomedicine“ part of biomedical egineering with application of nanomaterials. Key words: water, exclusion zone, hydrphobic and hydrofilc materials, hydrogen bonding, quantum superposition, nanomaterials, biomolecules
