1. A polymer having a structure of the following formula (I):

OG Complex Work Unit Chemistry
wherein:
POLY is a triblock copolymer of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide);
m and n are independently from each other 0 or 1, wherein m and n cannot be 0 simultaneously; and
AA is an amino acid residue, where its amino group directly binds to the chain-end of the POLY to form carbamate (O—C(═O)—NH) linkage.
