The present study aimed to extract nanocellulose (NC) from sugarcane bagasse agricultural waste through a chemical method (sulfuric acid hydrolysis and ultrasonication). Subsequently, the product was conjugated with polylysine (NC–PL) assessed for its efficacy in reducing toxicity of Fumonisin B1 (FB1), mycotoxin produced by fungi commonly found corn, wheat, other grains. Experimental results confirmed successful conjugation NC PL, as evidenced FTIR peaks at 1635 1625 cm−1 indicating amide I II vibrations (PL). SEM analysis revealed larger size due PL coating, consistent DLS showing increased positive charge (38.0 mV) on NC–PL surface. Moreover, effect FB1 adsorption evaluated various concentrations (0–200,000 μg/mL). demonstrated ability adsorb 2000, 20,000, 200,000 μg/mL, efficiencies 94.4–100%. Human hepatocellular carcinoma (HepG2) cells were utilized assess cytotoxic effects. This result is preliminary step towards standardizing future studies their application novel binders food, food packaging, functional feeds.
