Biosensors 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...
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 کاملTime-dependent conformational changes of polyelectrolyte complexes in solution
Changes in the conformation of the polyelectrolytes when contacted with oppositely charged polyelectrolytes or when subjected to shifts in solution conditions (pH), have been studied in this work along with reversibility of the changes using fluorescence spectroscopy. While changes due to both of the above are marked, they are measurably different from each other. Thus, the extent of coiling of...
متن کاملBiological polyelectrolyte complexes in solution and confined on patterned surfaces
In the first part of this paper we describe recently discovered structures in self-assemblies of charged membranes complexed with the biological polyelectrolyte DNA. These complexes are currently used in medical applications of non-viral gene delivery. The second part of the paper will describe entirely new experiments where liquid crystal and biological polymers are confined on lithographicall...
متن کاملPatterned Microstructure Fabrication: Polyelectrolyte Complexes vs Polyelectrolyte Multilayers
Polyelectrolyte complexes (PEC) are formed by mixing the solutions of oppositely charged polyelectrolytes, which were hitherto deemed "impossible" to process, since they are infusible and brittle when dry. Here, we describe the process of fabricating free-standing micro-patterned PEC films containing array of hollow or filled microchambers by one-step casting with small applied pressure and a P...
