Proteins are excellent templates and stabilizers for Au nanoclusters (NCs) because of their abundant thiol groups and unique internal environments. However, high-molecular weight (MW) proteins with special quaternary structures are rarely reported as such templates. Considering that proteins may afford different spatial configurations as templates for Au NCs, we focused on alkaline phosphatase, catalase,...
To form the PS/PAH fibers, positively charged poly(allylamine hydrochloride) (PAH) was coated on the surface of polystyrene (PS) fibers. Then, the ordered Hb‐PS/PAH film was prepared by the self‐assembly of hemoglobin (Hb) on the surface of fibers and characterized by electrochemical and spectroscopic methods. Cyclic voltammetry of the self‐assembled Hb‐PS/PAH films modified on glassy carbon electrode...
Recently, superparamagnetic nanoparticles of iron oxides have shown great potential in bio-applications, including magnetic resonance imaging contrast enhancement, drug delivery, bio-separation, tissue repair, hyperthermia, and others. In this study, we have explored the enhanced cytotoxicity effect of arsenic trioxide (As2O3) on both sensitive K562 cell line and adriamycin-resistance K562/A02 cell...
