Microcapsule composition using alginate gel, and method for producing same

A method of preparing microcapsules comprising:

• preparing microspheres composed of a material containing divalent cation (first step);
• coating surface of the microspheres with polydopamine by mixing a microspheres solution in which the microspheres are suspended and a dopamine solution (second step);
• conjugating polydopamine-coated microspheres (PD-MS) to surface of an object (third step);
• and
• coating surface of PD-MS-conjugated object with an alginate gel (fourth step).

An individual encapsulation method of an object comprising:

• preparing microspheres composed of a material containing divalent cation (first step);
• coating surface of the microspheres with polydopamine by mixing a microspheres solution in which the microspheres are suspended and a dopamine solution (second step);
• conjugating polydopamine-coated microspheres (PD-MS) to surface of an object (third step);
• and
• coating surface of PD-MS-conjugated object with an alginate gel (fourth step).
