Monocarboxylic acids are common solvents for chitosan to fabricate nanofibers however the unpleasant odor and the additional step of fiber stabilization using crosslinkers, which might cause toxicity, are always the points to be aware of. The present work demonstrates the potential use of multicarboxylic acids as environment-friendly solvents and in situ crosslinking agents for chitosan electrospinning. The use of these solvents leads to the tunable physicochemical properties, cellular compatibility, and cost effective production. By changing di-, to tri-, and tetracarboxylic acids combining with the simple thermal treatment, the stability and mechanical properties of the nanofibrous mats, especially the elastic modulus and elongation at break, can be altered. The resulting nanofibers exhibit biocompatibility favorable for proliferation and adhesion of the osteoblast cells. The multicarboxylic acids allow us lab-scale reproducibility and possibility to semi-production of nanofibrous chitosan using Nanospider™.
