ALB and colonic neoplasm: CPT‐albumin binding Evans blue prodrug self‐assembled into 80 nm of NPs that quickly altered to 7 nm albumin/prodrug nanocomplexes after being administratored, the nanocomplexes were efficient untaken into HCT116 colon cancer cells, exhibited 130‐fold greater long blood circulation than CPT and 30‐fold tumor accumulation of CPT in animal mode.[64]
