Abstract :In this study, flower shape hybrid protein-inorganic hybrid nanostructures were synthesized using a common protein (bovine serum albumin, BSA) and metal ion (Cu2+) at different protein concentrations (0.01, 0.02, 0.05, and 0.1mg mL-1) and pHs (PBS pH:6-9) at +4 oC for investigation of thermal properties the first time in detail. These synthesized protein-inorganic hybrid nanostructures (BSA-Cu3(PO4)2. 3H2O hNFs) were defined using SEM, EDX, elemental mapping XRD, FTIR, etc. Morphologies of BSA-Cu3(PO4)2.3H2O hNFs were characterized by SEM. Element analysis of BSA-Cu3(PO4)2.3H2O hNFs was achieved by EDX. Peak positions of BSA-Cu3(PO4)2. 3H2O hNFs were investigated using XRD. And, the FTIR technique was used to substantiate the creation of hNFs. Also, the thermal behavior such as glass transition and crystallization of BSA-Cu3(PO4)2.3H2O hNFs were investigated in detail using thermal gravimetric analysis (TGA).
