“…Therefore, the nanoparticles inclusion in PLA is regarded as an effective strategy to modify its properties and control the degradation behaviour in different media [17]. Several interesting properties of TiO2 such as strong antibacterial activity against diverse microorganisms (including algae, viruses, fungi, and bacteria), photocatalytic activity, high stability, good mechanical properties, non-flammable, resistance to corrosion, intense UV absorption, low cost, and nontoxicity make it beneficial for many applications [1,[18][19][20].…”
