a new folate-conjugated gold nanoparticle (aunp) has been designed to selectively target the folate receptor that is overexpressed on the surface of tumoral cells. for this purpose, we made 4-aminothiophenol, as a bifunctional linker to react with haucl4 in the presence of sodium borohydride and it was binded to the aunp surface through its thiol group. then, we conjugated amino-terminated nano...

objective: synthetic fluorescent dyes that are conjugated to antibodies are useful tools to probe molecules. based on dye chemical structures, their photobleaching and photostability indices are quite diverse. it is generally believed that among different fluorescent dyes, alexa fluor family has greater photostability than traditional dyes like fluorescein isothiocyanate (fitc) and cy5. alexa f...

Judiciously chosen side chains of conjugated molecules have a positive impact on charge transport properties when used as the active material in organic electronic devices. Amongst the side chains, oligoethylene glycols (OEGs) have been relatively unexplored due to their hydrophilic nature. OEGs also affect the smooth film formation of conjugated molecules, which preclude device fabrication. Ho...

Hydrogels possessing fine-adjustable and switchable elasticity emulate the mechanical microenvironments of biological cells, which are known to change dynamically during development disease progression. In this study, a supramolecular hydrogel conjugated with gelatin side chains was synthesized. By systematically screening molar fraction host/guest cross-linkers, Young’s modulus substrate fine-...

Conjugated polymers encompassing delocalized π-electrons in their backbones exhibit high photoabsorption and efficient charge carrier transport through the intermolecular π-π stacking suitable for organic photovoltaics (OPV). By contrast, small molecules such as [1]benzothieno[3,2-b][1]benzothiophene (BTBT) derivatives, which demonstrates field-effect transistor hole mobilities owing to 2-dimen...
