Fabrication, Characterisation, and Biocompatibility of Graphene-loaded Polymannose-Chitosan Scaffold for Potential Drug Screening Applications

Abstract

Graphene-loaded polymannose-chitosan scaffolds have emerged as promising candidates for drug screening applications due to their unique properties. The combination of polymannose and chitosan, supplemented with graphene, offers a versatile platform with potential applications including drug screening. The aim of this study is to fabricate and characterize the biocompatible graphene oxide loaded polymannose chitosan scaffold (PM-Chi-GO) for potential drug screening applications. The scaffold was meticulously prepared by combining oxidized polymannose with chitosan hydrochloride and graphene oxide, employing gelation techniques. Characterization involved Fourier Transform Infrared Spectroscopy (FTIR) for functional group analysis and Scanning Electron Microscopy (SEM) for morphological studies. The biocompatibility of the scaffold was assessed using Peripheral Blood Mononuclear Cells (PBMCs). FTIR analysis revealed distinctive peaks at 3296, 1624, 1528, 1389, 1060, and 808 cm-1, corresponding to specific functional groups within the scaffold. SEM displayed a porous morphological structure. Biocompatibility testing with PBMCs demonstrated favorable responses, confirming the scaffold's potential for in vitro drug screening applications. The synthesized PM-Chi-GO is characterized by its unique structural and biocompatible properties and holds significant promise for future drug screening endeavors. This study establishes a foundation for the utilization of this scaffold in drug screening applications.
