Compact Polyelectrolyte Complexes: “Saloplastic” Candidates for Biomaterials
Precipitates of polyelectrolyte complexes were transformed into rugged shapes suitable for bioimplants by ultracentrifugation in the presence of high salt concentration. Salt ions dope the complex, creating a softer material with viscous fluid-like properties. Complexes that were compacted under the centrifugal field (CoPECs) were made from poly(diallyldimethyl ammonium), PDADMA, as polycation,...
متن کاملSaloplastic Macroporous Polyelectrolyte Complexes: Cartilage Mimics
Complexes of sodium poly(4-styrenesulfonate) (NaPSS) and poly(diallyldimethylammonium chloride) (PDADMAC) were formed on mixing equimolar solutions in high salt concentration. Under ultracentrifugal fields, the complex precipitates were transformed into compact polyelectrolyte complexes (CoPECs), which showed extensive porosity. The mechanical properties of CoPECS make them attractive for bioim...
متن کاملPolyelectrolyte–protein complexes
The field of polyelectrolye–protein complexes is now benefiting from the convergence of three themes whose disciplinary distinctions formerly produced fragmentation. Theory and simulations, previously restricted to isotropic models of colloids and polyelectrolytes, are now taking into account the heterogeneity of charges in both macroions and providing far more realistic depictions of proteins....
متن کاملChitosan-based polyelectrolyte complexes for drug delivery
Among different polymers, chitosan, the N-deacetylated product of the polysaccharide chitin, is gaining increasing importance in medical and pharmaceutical applications due to its good mucoadhesion and absorption enhancing ability. Moreover, chitosan shows the ability to form hydrogels able to control the rate of drug release from the delivery system as well as protect the drug from chemical an...
متن کاملBiosensors from conjugated polyelectrolyte complexes.
A charge neutral complex (CNC) was formed in aqueous solution by combining an orange light emitting anionic conjugated polyelectrolyte and a saturated cationic polyelectrolyte at a 1:1 ratio (per repeat unit). Photoluminescence (PL) from the CNC can be quenched by both the negatively charged dinitrophenol (DNP) derivative, (DNP-BS(-)), and positively charged methyl viologen (MV(2+)). Use of the...
