The current study explores the synergistic application of biophysical chemistry and nanotechnology in therapeutic treatments, focusing specifically on the development of advanced biomaterials to repurpose FDA-approved Alzheimer's disease (AD) drugs as potent antioxidants. By integration of AD drugs into graphene oxide (GO) nanocomposites, an attempt to enhance the acetylcholinesterase (AChE) inhibition and increase radical scavenging activity is proposed. This bionano synergy is designed to leverage the unique properties of both the nanomaterial surface and the bioactive compounds, improving treatment effectiveness. The nanocomposites also promise targeted drug delivery, as GO can traverse the blood-brain barrier to inhibit AChE more effectively in AD patients. Furthermore, the drug-GO nanocomposite exhibits enhanced radical scavenging capabilities, offering additional therapeutic benefits. This study also elucidates a molecular level understanding on how the properties of the drugs are modified when integrated into nanocomposites with GO, enabling the development of more effective materials. The interdisciplinary approach presented in this study exploits the potential of nanotechnology to enhance drug delivery systems and achieve superior therapeutic outcomes through bionano synergy.
