Ethylenediaminediacetic acid bis(carbido amide chitosan): Synthesis and evaluation as solid carrier to fabricate nanoemulsion

► Ethylenediaminediacetic acid bis(carbido amide chitosan) (ED-chitosan) microparticles were synthesized. ► The ED-chitosan microparticles were characterized using FTIR-ATR, SEM, TEM and DSC analysis. ► We examined microparticles employing OAC, ADC, surface free energy and dynamic advancing contact angle. ► The potential of ED-chitosan microparticles for the fabrication of nanoemulsion was evident.
