Fourier Transform Infrared Spectroscopy spectra (A) Chitosan raw material (B) Cefotaxime raw material (C) bare CSNPs (D) cefotaxime loaded CSNPs. FTIR spectrum of powders were taken after mixing raw material with KBr. Whereas liquid samples were analyzed directly by palcing a tiny drop over glass assembly. FTIR spectra indicated no new bond formation so the drug is not reacting chemically with nano-scaffolds.
