Abstract
Studies were performed to investigate the influence of nanoparticles with magnetic core Fe3O4 on biomembrane model systems, based on DMPC. NP's were synthetized using standard methods [1,2] and characterized by TEM, magnetic (SQUID) and Raman spectroscopies. Samples with 10% DMPC and different concentrations of NP's were examined by ATF-FTIR to establish the impact of NP's on phase behavior of model phospholipids systems. NP's with magnetic core have attractive properties which can be used in biomedical application (for example MRI), so also were done measurements to define the nanotoxicity on model systems at physiological temperature of human body.
