Introduction: Aflatoxin leads to liver cancer, its removal in the foodstuff is very important. The aim of this study is to investigate the adsorption of aflatoxin B1 by nanocellulose conjugated with aptamer in acidic, alkali, and neutral conditions.

Methods: First, nanocellulose was synthesized by acid hydrolysis and then conjugated with aptamer by cross-linker. Then, serial concentrations of conjugated nanocellulose (0.6, 1.25, 2.5, 5, and 10 mg/mL) were separately mixed with aflatoxin solution (1000µg/mL), and incubated at  37 °C for 0.5 h at pH of 1, 7, and 13. Then, the percentage of aflatoxin adsorption was measured at 340 nm.  

Results: The decrease of pH led to increase of adsorption up to 40%. Statistically, there was significant difference between the quantity of adsorption at acidic condition and the quantity of adsorption at alkali and neutral conditions (P<0.05).

Conclusion: Aflatoxin could be adsorbed by conjugated nanocellulose, and this power of adsorption is increased at acidic condition.
