AB  - Phosphorylation is a key route to achieve varieties of biological activities for 
      polysaccharides. Here, we report the phosphorylated surface deacetylated chitin 
      nanofibers (PS-ChNFs) using the sodium tripolyphosphate/sodium trimetaphosphate 
      (STPP/STMP) method. Response surface methodology (RSM) was employed to optimize 
      in this study. Under optimal conditions, a maximum degree of substitution (DS) of 
      0.13 was obtained. In addition, the structures of PS-ChNFs were investigated by 
      Fourier transform infrared spectroscopy (FT-IR), Nuclear Magnetic Resonance 
      spectra (NMR), X-ray photoelectron spectroscopy (XPS), Scanning electron 
      microscope (SEM) and (Energy Dispersive Spectroscopy-mapping) EDS-mapping. The 
      findings revealed that the FT-IR spectroscopy and XPS analysis confirmed the 
      appearance of phosphate groups in PS-ChNFs. The (31)P NMR results indicate that 
      the PS-ChNFs structure has characteristic peaks of P elements. SEM images showed 
      that PS-ChNFs had a rough surface with many cavities, but the P elements on the 
      surface of the EDS-mapping are uniformly distributed throughout the sample 
      without any enrichment. Antioxidant and antibacterial test showed that PS-ChNFs 
      had significant scavenging effect on free radicals and antibacterial effect. The 
      above results indicate that the chemical modification of PS-ChNFs was successful.
