For this purpose, two-step procedure is applied in the presence of phenylbis (2,4,6-trimethylbenzoyl)phosphine oxide (BAPO) as bifunctional photo initiator. Based on spectroscopic and chromatographic analyses, the desired amphiphilic block copolymer (PMML-b-POEGMA) is successfully synthesized by wavelength-selective free radical photopolymerization under mild conditions. Finally, the DOX drug is loaded into the PMML-b-POEGMA micelles and then drug release behavior is investigated at two different pH (5.5 and 7.4) values. It is concluded from the results that PMML-b-POEGMA micelles may be used as an efficient nanocarrier to deliver conventional anti-cancer drugs for combination chemotherapy.eninfo:eu-repo/semantics/closedAccessamphiphilicdrug releaselithocholic acidphotopolymerizationArticle10.1002/pat.5478321248604868N/AN/A
