Other than the nanocarriers responsive to the most common stimuli described above, there are various reports in the hterature on DDS that release their payload in response to other triggers, such as exogenous light, ultrasound and magnetic field, as well as endogenous glucose and ions.lhese are described briefly in the following subsections.
