This study describes the development and characterization of curcumin with graphene oxide complex (CUR + GO) loaded into liposomes for treating skin disease. The developed complex was characterized by X-ray diffraction and showed a broad halo pattern, confirming the amorphous nature of the resulting complex. Furthermore, scanning electron microscopy revealed the irregular porous morphology of the complex-highlighting loss of the crystallinity and the emergence of the amorphous phase. Additionally, the liposomes showed long-term stability at 2-8 degrees C and 25 +/- 2 degrees C/60 +/- 5%RH with nonsignificant variations in the particle size, polydispersity index, and zeta potential. Overall, optical and high-resolution transmission electron microscopy images of liposomes showed a consistent shape, and no aggregation with uniform particle size distribution was observed. Furthermore, the cumulative drug release in the first 6 h was 71.24 and 64.24% for CUR-loaded liposomes and CUR-GO-loaded liposomes, respectively. The lower value of drug release might be attributed to the complex development. The drug release model found the first order with non-Fickian diffusion process, which is often observed at higher n > 0.5. The antibacterial activity of the CUR with GO-loaded liposome (D2) offered higher anti-microbial activity over other formulations against the mentioned bacterial microorganism that causes skin diseases.
