dc.description.abstract | Synthetic polymers are widely used in medical devices and implants where biocompatibility and mechanical
strength are key enablers of emerging technologies. One concern that has not been widely studied is the potential
of their microplastics (MPs) release. Here we studied the levels of MP debris released following 8-week in vitro
tests on three typical polyglycolic acid (PGA) based absorbable sutures (PGA 100, PGA 90 and PGA 75) and two
nonabsorbable sutures (polypropylene-PP and polyamide-PA) in simulated body fluid. The MP release levels
ranked from PGA 100 > > PGA 90 > PGA 75 > > PP ~ PA. A typical PGA 100 suture released 0.63 ± 0.087
million micro (MPs > 1 µm) and 1.96 ± 0.04 million nano (NPs, 200–1000 nm) plastic particles per centimeter.
In contrast, no MPs were released from the nonabsorbable sutures under the same conditions. PGA that was coblended with 10–25% L-lactide or epsilon-caprolactone resulted in a two orders of magnitude lower level of MP | en |
