Claim 0:
1. A method of synthesizing a multicompartment capsule, comprising the steps of:
I. forming at least one plurality of polymer capsules via a capsule-forming process, wherein said capsule-forming process comprises:
A. providing a feed solution comprising a biopolymer;
B. providing a reservoir solution comprising a biopolymer, wherein said feed solution biopolymer and said reservoir solution biopolymer have opposite charges; and
C. introducing droplets of said feed solution into said reservoir solution, thereby forming via electrostatic complexation a plurality of polymer capsules;

II. encapsulating at least one polymer capsule(s) from said formed plurality of polymer capsules in an outer polymer shell, comprising:
A. providing a feed solution comprising a biopolymer and at least one polymer capsule(s) from said formed plurality of polymer capsules;
B. providing a reservoir solution comprising a biopolymer, wherein said feed solution biopolymer and said reservoir solution biopolymer have opposite charges; and
C. introducing droplets of said feed solution into said reservoir solution, thereby forming via electrostatic complexation a plurality of outer polymer shells, wherein at least one of said outer polymer shells encapsulates said at least one polymer capsule(s), thereby forming a multicompartment capsule,
wherein said feed solution of either of steps I (A) or II (A) further comprises a payload, wherein at least one polymer capsule(s) from savid formed polymer capsules encapsulates said payload.
