Cellular uptake of biotransformed graphene oxide into lung cells

Due to its high surface area and convenient functionalization, graphene oxide has many potential applications in biomedicine, especially as a drug carrier. However, knowledge about its internalization inside mammalian cells is still limited. Graphene oxide cellular uptake is a complex phenomenon affected by factors such as the size of the particle and modifications of its surface. Moreover, nanomaterials introduced into living organisms interact with biological fluids' components. It may further alter its biological properties. All these factors must be considered when the cellular uptake of potential drug carriers is considered. In this study, the effect of graphene oxide particle sizes on internalization efficiency into normal (LL-24) and cancerous (A549) human lung cells was investigated. Moreover, one set of samples was incubated with human serum to determine how the interaction of graphene oxide with serum components affects its structure, surface, and interaction with cells. Our findings indicate that samples incubated with serum enhance cell proliferation but enter the cells with lesser efficiency than their counterparts not incubated with human serum. What is more affinity towards the cells was higher for larger particles.
