Cytotoxicity of BNNS coated with chitosan preparations with different molecular weights. (A) Peripheral blood mononuclear cells. (B) 293XL-hTLR9 cells.

Notes: These BNNS did not show cytotoxicity up to a concentration of 100 μg/mL. The cells were incubated with increasing concentrations of BNNS-CS complexes, and cell viability was measured using a water-soluble tetrazolium salt assay. The data are presented as the mean ± standard deviation (n = 5).

Abbreviations: CS, chitosan; BNNS, boron nitride nanospheres; CS-L, chitosan with a molecular mass of 60–120 kDa; CS-M, chitosan with a molecular mass of 110–150 kDa; CS-H, chitosan with a molecular mass of 140–220 kDa.
