A method has been developed to form capsules with liquid cores where permeability can be modified without sacrificing membrane strength. The capsule is formed by dropwise addition of a 3% chitosan (polycation) solution into a 0.75% alignate (polyanion) solution. The resultant capsule consists of a liquid chitosan core with a hard alginate coating. The addition of CaCl 2 to chitosan and glucose to alginate increased capsule strength. The membranes formed were strong enough to require up to 100 Newton during uniaxial compression to burst a 6.4 mm diameter capsule.
