Characteristics of the block copolymers

Polymer Code Sizea (Deff, nm) PDI Zeta potential (mV)a
PEG-b-PLL-b-PLA TM 94±4 0.18±0.03 +18.1±0.7
PEG-b-PLL(-g-Ce6)-b-PLAb CTM 112±14 0.22±0.02 +12±2
PEG-b-PLL(-g-Ce6, DMA)-b-PLAc CDTM 94±2.2 0.20±0.02 −14±2.5

Notes:

a

Particle size, PDI, and zeta potential were measured using DLS equipment;

b

Molar ratio between l-lysine and Ce6 =15:1;

c

Molar ratio between l-lysine, Ce6, and DMA =15:1:9.
