AB  - Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was employed to analyse 
      cellulose viscose fibres treated with different chitosan-based solutions. The 
      analysis reports several new features in the TOF-SIMS spectra for systems with 
      various forms of chitosan-treated surfaces. The characteristic positive ion 
      TOF-SIMS signals for chitosan are reported at m/z 147.90, 207.07, and 221.09, and 
      characteristic signals for trimethyl chitosan are present at m/z 58.03 and 
      102.09. Furthermore, new fragments were suggested to characterise acetylated 
      chitosan molecules. The relative surface concentrations of different species were 
      obtained based on the specific signal ratios (originating from a specific 
      fragment and cellulose). SIMS imaging was then performed in order to investigate 
      the surface distribution of chitosan, trimethyl chitosan, and Na-containing 
      nanoparticles. In order to perform TOF-SIMS imaging, the above-mentioned 
      characteristic signals were employed and m/z 22.99 was used for Na nanoparticles.
