Description
| - A special type of self-association of macromolecules is investigated that leads to creation of nanoparticles in a liquid environment (water, organic solvents, liquid mixtures). Nanoparticles are created by a change in an external parameter, usually temperature or pH. Short-range attraction and long-range repulsion are required for controlled self-association. Various physical interactions are used to provide the short-range attraction: hydrogen bonding, thermoresponsive association of polypeptides, selective sorption of incompatible solvents to diblock copolymers. Long-range repulsion is provided by the incompatibility between the blocks and/or incompatibility of blocks with the surrounding liquid. The repulsion depends on external variables. Polymeric nanoparticles can be created permanently or be reversibly disassembled by an inverse change of the external stimulus. They can also be permanently disassembled by degradation. Efforts will be made to control their size, polydispersity and structure as required by applications envisaged in drug delivery, nanocontainers or nanoreactors. (en)
- Podstatou projektu je výzkum speciálního typu asociativního chování makromolekul, které vede k tvorbě nanočástic v kapalném prostředí (voda, organická rozpouštědla, směsi kapalin). Nanočástice vznikají reakcí na změnu externího parametru, obvykle teploty nebo pH. Pro řízenou tvorbu nanočástic systém musí mít přitažlivé interakce na krátkou vzdálenost a odpudivé interakce na dlouhou vzdálenost. Jsou používány různé fyzikální interakce působící přitažlivě na krátkou vzdálenost: vodíkové můstky, termoresponsivní asociace polypeptidů, selektivní sorpce nemísitelných rozpoštědel na blokový kopolymer. Odpudivá interakce je vyvolána nekompatibilitou mezi bloky nebo bloků a okolního prostředí, rovněž závisí na vnějších proměnných (teplota, pH). Nanočástice jsou vytvořeny buď trvale nebo mohou být reverzibilně rozloženy opačnou změnou vnější proměnné. Mohou též být trvale rozloženy degradací. Pozornost bude soustředěna na řízení rozměru, polydisperzity a struktury nanočástic v hodnotách odpovídajících zamýšleným aplikacím v oblasti cíleného transportu léčiv, nanokontejnerů, nanoreaktorů.
