Aerogels Based on Chitosan and Collagen Modified with Fe₂O₃ and Fe₃O₄ Nanoparticles: Fabrication and Characterization

The necessity to mitigate the intrinsic issues associated with tissue or organ transplants, in order to address the rising prevalence of diseases attributable to increased life expectancy, provides a rationale for the pursuit of innovation in the field of biomaterials. Specifically, biopolymeric aer...
