Nanocomposites with functions of biomedical nanorobots — •Ievgen Pylypchuk and Petro Gorbyk — Ukraine, Kyiv, Gen. Naumov str. 17

The modern level of nanotechnology permits creating unique means for medicine and biology. Their introduction into practice is the basis of the contemporary progress in diagnostics and therapy, in particular, at the cell and genetic levels. Researchers* interest in magnetosensitive biocompatible nanoparticles arises from the possibilities to control their motion in biological medium by external magnetic *eld, use for targeted drug delivery, form local hyperthermia zones, create new types of adsorbents, means for early diagnostics of diseases, etc.

Recent advances in cross-disciplinary nanoscience and nanotechnology have led to further and rapid developments of new *nanohybrids* as probes for molecular imaging, MRI, neutron capture therapy(NCT), targeted drug delivery, different kinds of therapy which are sensitive to pH, magnetic field, neutron irradiation etc. All of these parametres inherent to biomedical nanorobots.

Developed methods of immobilization of different bio-compounds on to surface of nanosized magnetite. Nanocomposites was characterized by vibrating sample magnetometry, IR-spectroscopy, X-ray diffraction and X-ray photoelectron spectroscopy etc.
