BACKGROUND AND OBJECTIVE Superparamagnetic iron oxide nanoparticles (SPIONs) emerge as a promising tool for early cancer diagnostics and targeted therapy. However, both toxicity and biological activity of SPIONs should be evaluated in detail. The aim of this study was to synthesize superparamagnetic cobalt ferrite nanoparticles (Co-SPIONs), and to(More)
Experimental data presented in the paper can be re-plotted in the form of the complex capacitance Nyquist plots. These plots offer a convenient way to analyze the capacitive behavior of the electrode impedance. The Im Y/ vs Re Y/ (where Y is the electrode admittance and  is the angular frequency) plots obtained at various stages of the alumina matrix(More)
We report the design and methodology for functionalization of the surface of small Co-ferrite nanoparticles with a mean size of up to 5.0 nm through the attachment of vitamin C molecules initiating [AuCl4]-reduction and the subsequent deposition of gold. By this method, Co-ferrite-Au nanoparticles have been fabricated for the first time in a simple and(More)
In this study, conditions for the fabrication of extremely thin and flexible anodic films decorated with silver nanowire arrays by alternating current treatments for the finishing of high purity and commercial aluminium foils were developed. For characterization of these porous films with a thickness of ≤1.0 μm and encased silver species, inductively(More)
