“…Biomedical polymers are products employed to reproduce the function of living tissues in biological systems in a safe, mechanically functional, and physiologically acceptable way [7]. They are implanted in the body (temporarily or permanently), and they try to restore the existing defect by activating tissue regeneration, decreasing the probability of infection, and minimizing patient discomfort [7,8]. In the case of sutures, many factors must be considered, such as the required tension and the biological reaction to the material that occurs in sutures based on synthetic polymers.…”

Preparation of Surgical Thread from a Bioplastic Based on Nopal Mucilage

et al. 2023

Currently, natural materials represent a sustainable option for the manufacture of biopolymers with numerous industrial applications and characteristics comparable with synthetic materials. Nopal mucilage (NM) is an excellent natural resource for the synthesis of bioplastics (BPs). In the present research, the fabrication of biopolymers by using NM is addressed. Changes in the plasticizer (sorbitol and cellulose) concentration, in addition to the implementation of two sources of starch (corn starch (CS) and potato starch (PS)) to obtain the surgical thread, were analyzed. The NM extracted was close to 14% with ethanol. During the characterization of the extract, properties such as moisture, humidity, viscosity, and functional groups, among others, were determined. In the CS and PS analysis, different structures of the polymeric chains were observed. BP degradation with different solvents was performed. Additionally, the addition of sorbitol and cellulose for the BP mixtures presenting the highest resistance to solvent degradation and less solubility to water was conducted. The obtained thread had a uniform diameter, good elasticity, and low capillarity compared to other prototypes reported in the literature.

“…The proportion of these monomers in their composition changes depending on factors such as variety, age, environmental conditions, and structure (fruit, shell, or cladode) used for extraction [22,23]. Nonetheless, mucilage is considered a residue commonly discarded by consumers [8,14,18].…”
