ABSTRACT
Different blood groups of ABO system have specific antigen which bestows them with different biochemical properties and hence they can show different hemolytic activity. In this report, hemolytic activity of thiol-functionalized Fe3O4-Au nanoparticles were studied in presence and absence of doxorubicin and the effect of various thiol coatings were correlated towards their hemolysis tendency. The nanoparticles were functionalized with four different amino thiols, cysteamine (CEA), cystamine (CA), cysteine (Cys) and cystine (Cyt) to form Fe3O4-Au CEA, Fe3O4-Au CA, Fe3O4-Au Cys and Fe3O4-Au Cyt nanoparticles which were loaded with anticancer drug, doxorubicin. The functionalization was characterized using ATR-FTIR, HR-TEM, XPS and other spectroscopic methods. Maximum drug encapsulation efficiency of 83% was observed with Fe3O4-Au CA nanoparticles. In-vitro experiments were performed on HeLa cells to check the cellular uptake and cytotoxicity using MTT assay. Hemolytic activity was then analyzed with all the blood groups (positive and negative). The amino acid functionalized, Fe3O4-Au Cys and Fe3O4-Au Cyt nanoparticles, shows lesser hemolysis compared to amino thiol functionalized Fe3O4-Au CEA, and Fe3O4-Au CA nanoparticles. In positive blood groups, the Fe3O4-Au CA nanoparticles shows the highest rate of hemolysis followed by Fe3O4-Au CEA, while the lowest hemolysis rate was observed for Fe3O4-Au Cyt nanoparticles. For negative blood groups, the thiol coated nanoparticles show more abrupt hemolysis rate depending upon the type of antigen.
