AB  - The study encompasses an investigationof optical, photothermal and biocom-patibility properties of a composite con-sisting of golden cores surrounded bysuperparamagnetic CoFe 2 O 4 nanoparti-cles. Accompanied with the experiment,the computational modeling reveals that each adjusted magnetic nanoparticleredshifts the plasmon resonance frequency in gold and nonlinearly increases theextinction cross-section at 800 nm. The concentration dependent photothermalstudy demonstrates a temperature increase of 8.2 K and the photothermal con-version efficiency of 51% for the 100 μg/mL aqueous solution of the compositenanoparticles, when subjected to a laser power of 0.5 W at 815 nm. During anin vitro photothermal therapy, a portion of the composite nanoparticles, initiallyseeded at this concentration, remained associated with the cells after washing.These retained nanoparticles effectively heated the cell culture medium, result-ing in a 22% reduction in cell viability after 15 min of the treatment. The com-posite features a potential in multimodal magneto-plasmonic therapies.

AB  - Initial results en route toward construction of complex magnetic core-shell silica and organosilica nanotheranostics are presented. Magnetite nanoparticles are synthesized by three different methods and embedded within mesoporous silica and organosilica frameworks by different surfactant-templated procedures to produce three types of core-shell nanoparticles. Magnetite nanoparticles (15 nm in diameter) are embedded within mesoporous silica nanoparticles to produce cell-like material with predominantly one magnetite nuclei-resembling core per nanoparticle, with final particle diameter of ca. 150 nm, specific surface area of 573 m(2)/g and hexagonally structured tubular pores (2.6 nm predominant diameter), extended throughout the volume of nanoparticles. Two forms of spherical core-shell nanoparticles composed of magnetite cores embedded within mesoporous organosilica shells are also obtained by employing ethylene and ethane bridged organobisalkoxysilane precursors. The obtained nanomaterials are characterized by high surface area (978 and 820 m(2)/g), tubular pore morphology (2 and 2.8 nm predominant pore diameters), different diameters (386 and 100-200 nm), in case of ethylene- and ethane-composed organosilica shells, respectively. Different degree of agglomeration of magnetite nanoparticles was also observed in the obtained materials, and in the case of utilization of surfactant-pre-stabilized magnetite nanoparticles for the syntheses, their uniform and non-agglomerated distribution within the shells was noted.
