AB  - The present work highlights the formation of a novel green nanofiber based on 
      H(2)O(2)-assisted water-soluble chitosan/polyvinyl alcohol (W(S)CHT/PVA) by using 
      water as an ecofriendly solvent and genipin used as a nontoxic cross-linker. The 
      20/80 blend ratio was found to have the most optimum uniform fiber morphology. 
      W(S)CHT retained the same structure as W(IS)CHT. The prepared nanofibers were 
      characterized by Scanning electron microscopy (SEM), Fourier transform 
      spectroscopy (FTIR), Thermo gravimetric analysis (TGA), Differential scanning 
      calorimeter (DSC), X-ray diffraction (XRD), Water Contact Angle (WCA) and 
      Ultraviolet-visible spectroscopy (UV-vis). During electrospinning, the 
      crystalline microstructure of the W(S)CHT/PVA underwent better solidification and 
      after cross-linking there was an increase in the melting temperature of the 
      fiber. Swelling ratio studies revealed noticeable increase in hydrophilicity with 
      increase of W(S)CHT, which was further demonstrated by the decrease of contact 
      angle from 64.74 degrees  to 14.68 degrees . W(S)CHT/PVA nanofiber mats exhibit excellent UV 
      blocking protection with less than 5% transmittance value and also showed 
      improved in vitro drug release properties with stable release for longer duration 
      (cross-linked fibers) and burst release for shorter duration (uncross linked) 
      fibers. Finally our experimental data demonstrates excellent adsorption ability 
      of Colour Index (C.I.) reactive black 5 (RB5) due to protonated amino groups.
