“…In this epidemic, medical materials make a particular and irreplaceable contribution. Pathogens could easily colonize the surfaces of medical materials and pose significant safety risks, causing human infections 2 . The preparation of biological materials with antibacterial properties is an effective strategy to deal with this problem.…”

Bacterial infection caused by medical material is a common problem in the field of medicine. In this work, we aim to develop a novel antimicrobial bioplastic with potential medical value. A novel composite material composed of polyamino acid (PAA) and titanium dioxide/silver nanoparticles (TiO2/Ag NPs) was synthesized by in situ melting polycondensation with different TiO2/Ag loadings. The morphological, antibacterial, mechanical, thermal, and cytotoxicity properties of the PAA/TiO2/Ag composites were investigated. The results showed that uniform nanocomposites with amide bonds were synthesized, and the nanocomposites with 10% TiO2/Ag incorporation exhibited the best thermal and mechanical properties. Cytotoxicity assay showed that the composites significantly promoted the proliferation of MG‐63 cells. The composites showed obvious inhibitory effect on both Escherichia coli and Staphylococcus aureus, and this effect was increased as the TiO2/Ag NPs doping was increased. These PAA/TiO2/Ag composites are suitable for antibacterial and high‐performance biomaterials in the medical field.

Amid the 4th wave of COVID-19, Vietnam reopened its economy, which placed extra burdens on the COVID-19 waste management system. This study analyzed existing issues and recommended adaptations to secure appropriate management of COVID-19 waste under the ‘new normal’ pandemic period. Results showed changes in COVID-19 waste characteristics (e.g., rapid rise in waste generation, lower percentage of plastic) and multiple other issues (e.g., presence of COVID-19 waste in municipal waste, lack of temporary storage sites and local treatment capacity), along with greater waste-handling responsibilities placed on authorities and higher infection risks. To adapt to the ‘new normal’, introduction of separate handling routes and collaboration in waste treatment were recommended. Employing the network of pharmacies used for vaccination would require COVID-19 waste collection from scattered, small-scale sources as part of the waste management solution. Also, following the 4R initiatives (reduce, reuse, recycle, recovery) could help ease the burden on the country’s waste system and provide additional opportunities to move towards a circular economy in the post-acute COVID-19 era. The findings should contribute to a safer co-existence with the virus through appropriate waste management in Vietnam and could be used to tackle waste problems in other developing countries.
