Characterization of BNNS-CS complexes. (A) Zeta potentials in phosphate-buffered solution (pH 7.4) for BNNS and BNNS coated with chitosan preparations of different molecular weights. BNNS coated with chitosan have positively charged surfaces; this charge increases with their molecular weight. (B) Fourier transform infrared spectra of BNNS, CS, and BNNS-CS complexes.

Notes: BNNS-CS complexes clearly display the peaks assigned to both BNNS and CS, which confirmed the success of the coating.

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.
