Single-step ۳D printing of porous structures based on carboxymethylchitosan for wound dressing application

The chitosan and its Carboxymethyl chitosan derivatives can be used as promising wound dressingmaterials. The high biocompatibility, biodegradability, excellent antimicrobial activity, andnontoxicity of Carboxymethyl chitosan prove that it is an exceptional material for wound healingapplications. Porous structures are suitable for wound dressing applications, however, the fabricationof such structures by conventional additive manufacturing methods has many limitations. In thisstudy, porous structures were fabricated using the immersion precipitation ۳D printing method, whichis based on phase separation. The produced Carboxymethyl chitosan was analyzed using an FTIRspectrometer to confirm its structure. The morphology of the ۳D-printed structures was studied usingscanning electron microscopy (SEM).
