Abstract:
The quest to understand drug delivery to a specific site, quantity, or time has led to various method of trying to control drug delivery. If controllable drug delivery is mastered, managing and treating diseases will improve dramatically. Liposomes, microsomes and hydrogel are currently been used for these purpose. Hydrogels with three dimensional network of hydrophilic polymers are being considered because of their biocompatibility, minimal mechanical irritation, low cost, and ability to crosslink. Electro-responsive hydrogels are now been favored as to others such pH, temperature and light stimulated hydrogel because of the availability of the equipment, precise control on the magnitude of current, intervals and duration of electric pulses. Incorporating graphene in this hydrogel can also in improving drug delivery.
