In vitro cytotoxicity and haemolytic assay: cell toxicity was assessed using a MTT assay. L929 cells were treated with different concentrations i.e., from 0 to 4000 µM of the DNPs for 24 h. Viability was expressed as the percentage of media control. b LDH release assay: cells treated with 50 µM of DNPs showed almost similar release of LDH like PBS treated cells. Cells treated with DMSO as positive control showed the maximum LDH release. c Percentage haemolysis at three different concentrations. None of the DNPs showed haemolytic activity. Triton X-100 taken as a positive control showed 100 % haemolysis
