Polyelectrolyte–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 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...
متن کاملStepwise disproportionation in polyelectrolyte complexes
Structural properties and the topology of polyelectrolyte complexes (PECs) formed in solution have been investigated under different conditions by Monte Carlo simulations using a coarse-grained model. The extension of individual polyions has been characterized by their radius of gyration, whereas the composition of the complexes has been investigated by their net charge and their internal topol...
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...
متن کاملWavelet-based watermarking algorithms: theory, applications and critical aspects
The copyright protection of digital images is a critical element for multimedia applications on Web, electronic libraries and virtual image galleries. Since the middle of the nineties, digital watermarking techniques have been proposed as a streamlined solution to solve the copyright problem. In this article we present the difficulties occurred during the construction and the experimentation of...
