Graphene Quantum Dots from Carbonized Coffee Bean Wastes for Biomedical Applications.

摘要: Recent studies concerning graphene quantum dots (GQDs) focus extensively on their application in biomedicine, exploiting modifiable optical properties and ability to complex with various molecules via π-π or covalent interactions. Among these nascent findings, the potential therapeutic efficacy of GQDs was reported against Parkinson's disease, which has date remained incurable. Herein, we present an environmentally friendly approach for synthesizing through a waste-to-treasure method, specifically from coffee waste nanodrug. Consistent previous findings carbon fiber-derived GQDs, inhibitory effects bean-derived demonstrated similar effectiveness abnormal α-synuclein fibrillation protection neurons relevant subcellular damages. The fact that GQDs-based nanodrug can be prepared non-reusable yet edible source illustrates convert such materials into novel agents minimal psychological rejection by patients.
