Mutations in the zebrafish connexin43 (cx43) gene cause the short fin phenotype, indicating that direct cell-cell communication contributes to bone length. Three independently generated cx43 alleles exhibit short segments of variable sizes, suggesting that gap junctional intercellular communication may regulate bone growth. Dye coupling assays showed that all alleles are capable of forming gap ...

Dye-sensitized solar cells (DSSCs) have aroused intense interest owing to their easy fabrication, low cost, simple preparation procedures and high energy conversion efficiency. Considering the fact that leakage and volatilization of liquid electrolytes hinder their practical applications in the case of DSSCs, polymer electrolytes with high ionic conductivity, excellent thermal and long-term sta...

They studied how the complex responded to the primary constituents of blood serum: DNA, RNA, proteins and glucose molecules. We found that the sensor was extremely selective towards DNA even in the presence of RNA and proteins. DNA could be detected fluorescently with parts-per-million accuracy. It turns out that only DNA has the ionic strength capable of separating the PNPB dye from the graphe...

Preparation of bright fluorescent materials based on polymers is hampered by a fundamental problem aggregation-caused quenching (ACQ) encapsulated dyes. Here, ultrabright polymeric nanofibers and coatings are prepared concept ionic dye insulation with bulky hydrophobic counterions that overcomes the ACQ problem. It found counterion perfluorinated tetraphenylborate can boost >100-fold fluorescen...

Polyacrylonitrile-co-sodium methallylsulfonate copolymer (AN69) and polysulfone (PSf) synthetic membranes were prepared and used for the removal of methylene blue (MB) from water. Atomic Force Microscopy (AFM), Ionic exchange capacity (IEC), and Swelling ratio (Sr) were employed to determine the membrane characteristics. pH, membrane composition and initial dye concentration were used for t...
