 Redox responsive delivery systems have become increasingly popular in recent years due to their ability to respond to changes in the environment such as pH levels and oxidative stress. These systems are composed of two components, a redox sensitive carrier and a payload. When exposed to certain conditions, the carrier will undergo a chemical reaction that releases the payload into its desired location. This allows for more precise control over where the payload is delivered, resulting in improved efficacy and reduced side effects.
