Abstract Site specific delivery of anticancer drugs into tumour cells increase therapeutic efficacy while decreasing unwanted side effects. Oxaliplatin (Oxa) is a third-generation platinum derivative used to treat advanced colorectal cancer (CRC). Oxaliplatin loaded bovine serum albumin nanoparticles (Nps-Bsa-Oxa) were formulated by desolvation method. The Nps-Bsa-Oxa were characterized for their size, zeta potential (ZP), surface morphology and charge, in vitro Oxa release, release kinetics, in vitro cytotoxicity, and in vivo studies. The size and surface charge of the Nps-Bsa-Oxa was found to be 163.2 ± 6.3nm and − 27 mV respectively. The Oxa release was studied by dialysis, revealing a biphasic release pattern. In vitro cytotoxicity study was carried out by MTT assay using HT29 cell lines and the Nps-Bsa-Oxa showed higher cytotoxicity when compared with free drug Oxa. In vivo studies on animals revealed that Nps-Bsa-Oxa delivered more Oxa to the colonic region compared to the free form of the drug Oxa.
