What prevents toxicity of reduced graphene oxide in the body?5 answersReduced graphene oxide (RGO) toxicity in the body can be prevented through various methods. One approach is the functionalization of RGO with polymers such as polyethylene glycol, chitosan, and polyvinyl alcohol, which improves biocompatibility, decreases toxicity, and enhances clearance from organs. Another method is the use of a delivery system, such as graphene oxide (GO) nanoparticles, to load RGO. This delivery system can enhance the drug delivery effect of RGO and reduce its dark toxicity. Additionally, the synthesis techniques used for RGO fabrication play a crucial role in its biocompatibility. Techniques that involve the use of toxic organic solvents, surfactants, strong acids, and oxidants can introduce contaminants that interact with biological cells and tissues, leading to toxicity. Therefore, it is important to carefully select synthesis methods that minimize the presence of toxic residuals in RGO.
