Molecular structure changes of (a) AA and (d) CMC under an oxidization process. Illustration of recyclable processes of the (b) AA-DNA and (e) CMC-DNA bioplastics. Photographs of the (c) AA-5%DNA and (f) CMC-5%DNA bioplastics with different polysaccharide contents of 2%−20%. g Cytotoxicity assessment of the three bioplastic formulations, showing cell viability across concentrations. Data are presented as mean±standard deviation (n = 3). h Representative microscopy images of stained mice organ sections 14 days after ingesting Dex-DNA bioplastics, with comparisons to control group images. Examined organs include heart, intestine, kidney, liver, spleen, and stomach. i Representative microscopy images of stained mice stomach sections 14 days after exposure to AA-DNA and CMC-DNA bioplastics. The scale bar is 1 cm in (a–f) and 50 μm in (h, i).
