چکیده    Background: bromelain (bl) is an enzyme extracted from ananas comosus, which has been known for its therapeutic properties. objectives: the anticarcinogenic activity of bl was examined with and without the presence of magnetic carbon nanotubes (mcnts) against ht-29 colorectal cancer cells. methods: the operational factors affecting bl adsorption, such as contact time (30, 60, 90, 120, and 180 min), adsorbent dosage (1 g/l and 5 g/l), initial bromelain concentration (50, 150, and 300 mg/l), and temperature (35 and 50°c) were studied in details. then, cancer cells were exposed to various bl concentrations (0.1, 1, 10, and 100 μg/ml), and the cell viability was determined by methylthiazol tetrazolium (mtt) assay after 24, 48, and 72 h. results: the highest adsorption of bl on nanotubes was at 41.62 mg/l and achieved at 35°c and 90 min at the initial concentration of 50 mg/l and 1 g/l of mcnts. the adsorption followed the freundlich model and second-order kinetics. the results indicated that mcnts could be a potential effective adsorbent for the removal of bl. conclusions: mtt assay indicated that bl at a concentration of 100 μg/ml alone and in combination with mcnts efficiently inhibited the ht-29 cancerous cells. however, encapsulated bl had a considerable advantage of slow delivery, which is favorable for cancer treatment.
