Theranostic Nanoparticles: Magnetoresponsive iron oxide nanoparticles for biomedical use (OTKA NK84014)

Design and implementation of magnetic (magnetite - maghemite) nanoparticles  for MRI contrasting, hyperthermia and drug delivery: synthesis, surface modification (indifferent coating: PEG, Pluronics; CSA, PAA, PAM), functionalization and advanced characterization; samples for in vitro and in vivo tests.

2-D and 3-D aggregation of natural amphiphiles: BANAMOCA (HUSRB/1002/214/193, Hungary-Serbia IPA Cross-

border Co-operation Programme) Association of bile acids and their derivatives on floating films and aqueous phase and

their interaction with drugs in order to use Bile Acid Nanosystems as Molecule Carriers in Pharmaceutical Applications.

Magnetooptical materials: magnetic nanoparticles for magneto-optical thin film (FR TÉT_10-1-2011-0008, French- Hungarian Bilateral Cooperation) Synthesis of YIG (yttrium-iron oxide garnet) nanoparticles, samples for magneto-optical tests in Saint Etienne

pH-dependent surface charge characterization: various oxides (silica, alumina, titania, etc.) and clay (montmorillonite,

kaolinite, hectorite, imogolite) particles, active carbon, graphite oxide (GO), graphene oxide (SLGO), carbon nanotube

(CNT) nanoparticles

Colloidal aggregtion of soils and soil constituent particles: clay minerals, metal oxides (iron oxides, alumina, etc.),

humic substances - pH-dependent surface charge properties (acid-base titration, laser Doppler electrophoresis), colloid

stability: particle aggregation/dispersion (dynamic light scattering, rheology)
