There are several strategies that can be employed to increase the binding affinity of Doxorubicin to BSA, including:
1. Increase the number of binding sites on BSA: Chemical modification of BSA can increase the number of binding sites for Doxorubicin, resulting in increased binding affinity. For example, BSA can be modified with thiol groups, which can form covalent bonds with Doxorubicin.
2. Use of linker molecules: Linker molecules can be used to increase the contact area between Doxorubicin and BSA, thereby increasing binding affinity. For example, polyethylene glycol (PEG) can be used as a linker to increase the solubility and stability of BSA nanoparticles.
3. Optimization of pH and ionic strength: The binding affinity of Doxorubicin to BSA can be affected by pH and ionic strength. Optimization of these parameters can improve the binding affinity. For example, Doxorubicin has higher binding affinity to BSA at pH 7.4 compared to pH 5.0.
4. Use of molecular docking studies: Molecular docking studies can be used to predict the binding affinity of Doxorubicin to BSA, and to identify potential modifications to improve binding affinity.
