Amphiphilic di-block or tri-block copolymers that are capable of self-assembling into thermodynamically stable nano-structures with a hydrophobic core and hydrophilic corona, referred to as micelles, have become increasingly important in pharmaceutical applications.[1–5] The hydrophobic core can house hydrophobic drugs [6] and the hydrophilic corona functions as a steric barrier to prevent micelle aggregation ensuring micelle solubility in an aqueous environment.[7] To date, multiple synthetic amphiphilic micelle systems (Genexol-PM,[8, 9] NK012,[10] SP1049C,[11, 12] NC-6004,[13] and NK105 [14, 15]) are under clinical evaluation for delivering hydrophobic anti-cancer drugs. The size of these micelles typically range from 10 to 100 nm in diameter, and are composed of a hydrophilic corona, which prevents opsonization resulting in relatively long plasma retention times and reduced uptake by the reticuloendothelial system (RES).[16] The small size of these micelles allows them to accumulate in tumors through an enhanced
