sustained release drug products [58]. In the present medical domain, various medicines or drugs administered to patients are providing a wide range of side effects. Oral drugs are majority recurrent use of alginates in pharma applications, however use of alginate hydrogels as storing place for tissue confine drug delivery is growing [59]. Alginate gels are investigated for delivery of wide range of low molecular weight drugs and are very applicable at the moment that a primary or secondary linkage between drug and Alginate can be utilized to initiated kinetics of drug release [60]. Typically, alginate gel is nonporous, regulating rapid diffusion of small molecules through the gel.
