It is aimed to produce new graphene-based materials with potential used in biomedical applications. Method: The new GO-ZnPc hybrid was obtained by self-assembly method. Sonication was performed in the formation of hybrid. UV-Vis, emission spectra and scanning electron microscopy (SEM) were used to characterize ZnPc-GO hybrid formation. Results: The GO solutions of different concentrations (0.0005 µg / mL; 0.005 µg / mL; 0.05 µg / mL; 0.4 µg / mL; 0.7 µg / mL; 1 µg / mL) prepared by sonication were added to 10 µg / mL ZnPc solution separately and sonicated again. UV-Vis, emission spectra and scanning electron microscopy (SEM) were used to characterize ZnPc-GO hybrid formation. All measurements showed that intermolecular interactions occurred after mixing the two components together, and the resulting hybrid was stable. Conclusions: In this study, the new ZnPc-GO hybrid prepared and characterized. ZnPc and GO derivative was observed to well-coordinated. The obtained hybrid system was observed to have very interesting spectroscopic properties. It was observed that the GO-based ZnPc hybrid gave an absorption peak at 716 nm in the UV-Vis spectrum. The redshift observed with the ZnPc-GO hybrid formation in the UV spectra indicates that this material has the potential to be used in many biomedical applications, especially in tissue engineering and photodynamic therapy.
