Graphene oxide (GO) is a materials science material that has been attracting a lot of attention due to its unique properties, including excellent electrical conductivity and high surface area. One application of GO is in the field of drug delivery, where it can be used as an adsorbent to bind drugs to specific cells or tissues.

However, one potential concern about GO is its potential to interfere with the generation of ROS ( reactive oxygen species) in cells. ROS are produced by various cellular processes and have been shown to play a role in disease development and progression. There have been some studies that suggest that GO may act as a scavenger for ROS, which could potentially reduce the negative effects of GO on cell function.
One study published in the journal Nature Materials found that GO reduced the generation of ROS in mammalian cells by binding to certain enzymes involved in ROS production. The researchers attributed this reduction to the stability of GO as a functional material, rather than its chemical structure.
Another study published in the journal Nature Communications found that GO was able to prevent the formation of aggregates ofGO, which are formed when GO binds to proteins. This could potentially reduce the accumulation of GO in cells, which could have negative effects on cell function.
Despite these findings, there are still some concerns about the potential interference of GO with the generation of ROS. For example, the concentration of GO needed to activate the antioxidant activity may not be optimal for all cells. Additionally, the stability and functionality of GO as a material may vary depending on the conditions under which it is synthesized and used.

Overall, while there is some evidence to suggest that GO may interact with ROS and reduce their generation, further research is needed to fully understand the mechanisms by which GO interferes with the generation of ROS in cells. Additionally, optimizing the concentration and stability of GO as a material may help to minimize its negative effects on cell function.
