Effects of Hydrophobicity and Hydrophilicity on Adsorption of Blood Plasma Protein

In recent times, Nanoparticles (NPs) are used in medical practices especially for their contribution to drug delivery. Blood plasma protein binds to titanium dioxide nanoparticles and prevent the delivery of drugs to the intended target. When the protein binds to the NPs, the NPs in turn change the secondary structure of the blood plasma protein. This can affect drug delivery and thrombosis. The different shapes of these NPs influence the binding affinity and adsorption of the blood plasma protein. The research analyzed the NPs for two variables, shape and hydrophobicity. We conducted this experiment to further research effects of hydrophobicity and hydrophilicity of the NPs on the binding properties of the blood plasma protein. Fg had a higher binding affinity than HSA to the NPs. HSA failed to adsorb on any of the nanoparticles. Anatase had a higher binding affinity than the sample of NTs. These results indicate hydrophilicity and hydrophobicity does have an effect on protein adsorption. Further research could give us insight on the differences in secondary structure between NPs of different shapes and different levels of hydrophobicity or hydrophilicity
