Cationic pH-Responsive Microcapsules

Stimuli-responsive microcapsules are considered to be the most ideal intelligent drug delivery systems due to their relatively faster response rate and 

05 mol MBA, 0.05% w/v V50, 1% w/v Plutonic F127, 5% w/v glycerin the pH vaJue of the middle fluid was adjusted to 7.8. The compositions of irmer fluid and outer fluid are kept the same in all experiments. 

1 Cationic Polymeric Hydrogels with Rapid pH/Temperature-Responsive Property 

In many cases, multiple environmental stimuli may occur at the same time thus single stimuli-responsive hydrogels are insufficient for practical applications. Therefore, it is much more favorable that hydrogels possess 

Because of the introduction of freely mobile grafted side chains into the polymer backbone networks, the mobility of polymers in the comb-type grafted hydrogels is improved. The grafted chains inside the comb-type hydrogels can easily swell and shrink with environmental pH and/or
