Nanoparticles are small in size with maximized surface area and have an enhanced level of solubility; these elements result in an improved bioavailability. Reduction-Sensitive Nanoparticles are nanoparticles that are responsive to reduction signaling environments. Redox-Sensitive Nanoparticles can be responsive to signaling through a reduction activation or an oxidative activation. Therefore, degradation of chemical bonds can be either activated through oxidants or reductants in the localized area. The cleavage/degradation of chemical bonds will enable the drugs loaded within the nanoparticle to be released into the body. Depending on the activation mechanism, Redox-Sensitive Nanoparticles can be associated with Reduction-Sensitive Nanoparticles if the chemical activation method is through reduction.
