Ionically crosslinked hydrogels containing metal coordination motifs have piqued the interest of researchers in recent decades due to their self-healing and adhesive properties. In particular, catechol-functionalized bulk hydrogels have received a lot of a ...
In this paper the loaded polymer transport and its escape via a nanometer size aperture, virtually by nanomembrane, the polymer being moved by an exterior electrostatic field, has been studied. Assuming a linear dependency of the friction coefficient on th ...
Polymers containing PdnL2n complexes as network junctions were obtained by reaction of poly(ethylene glycol)-linked N-donor ligands with Pd2+. The addition of a metastable state photoacid renders the networks light sensitive, and gel–sol transitions can be ...
The coil to globule transition is a fundamental phenomenon in the physics of macro-molecules by reason of the multiplicity of arrangements of their conformation. Such conformational freedom is the main source of entropy in the molecule and is the main oppo ...
By shifting the balance between conformational entropy and internal energy, polymers modify their shape under external stimuli, such as changes in temperature. Prominent among such transformations is the coil-globule transition, whereby a polymer can switc ...
Small-angle neutron scattering and pulsed-gradient spin-echo NMR have been used to examine the solution conformation of a series of water soluble poly(N-(2-hydroxypropyl) methacrylamide) P(HPMA) co-polymer drug delivery vehicles incorporating a coiled-coil ...
Nanoparticles working together. Thermoresponsive polymer-coated nanoparticles are shown to display size dependent, cooperative, lower critical solution temperature behavior. This is exploited to direct the assembly of appropriate nanoparticles onto complem ...
The interactions and structural formation of polyelectrolytes in solution and environmental stimuli-responsive water-soluble polymers are subjects of intense academic research, development, and application. An increasing number of novel materials are being ...
Despite progress during the last decade, the behavior of charged macromolecules, polyelectrolytes, including their interactions is not yet completely understood. In particular, interactions with oppositely charged surfaces, which play a significant role in ...
Recent advances in the fields of biotechnology and medicine have intensified the necessity for pharmaceutical-grade biomacromolecules purification (e.g. enzymes, antibodies, plasmid DNA). One of the key factors for a successful downstream process is the po ...
