Project summary

It is widely accepted that upon the nanoparticles (NPs) entrance to the biological fluid their surface will interact with the medium’s components providing a new biological identity for NPs. The interface between particles and cell surface lipid bilayer comprises a series of dynamic interactions which are mediated by the protein corona and it is of great importance to follow the progressive events triggered during exposure to NPs at different time points to obtain relevant analysis valuable for therapeutic drug delivery or other purposes. Therefore, this work envisages a complex characterization of NPs interaction with the three major classes of biomolecules in order to associate the changes in nano-bio-interface with the specific physico-chemical properties of NPs and to obtain certain relationships very useful for further molecular modeling and simulation studies.

Project objective

The objective of the present project is represented by the complex analysis over time of the interaction between nanoparticles with different characteristics (chemical structures, sizes, surfaces) and biomolecules (proteins, lipids and nucleic acids).

Expected results for this project

The expected results will include a deeper understanding of nanoparticles’ biocorona, of their behavior in biological systems, and effect on molecules’ structures, in order to design further strategies for preventing toxicity induced by nanoparticles with well-established properties.
