“…In this year, Sunaryono et al successfully synthesized ZnO/TiO 2 nanocomposite by coprecipitation method. Their result shows that the inhabitation zone is greater than the individual nanoparticle, i.e., 7.71 mm for S. aureus and 13.40 mm for E. coli bacterial pathogens [76]. Dhanalekshmi et al [77] synthesized novel garlic-loaded WO 3 -TiO 2 chitosan (CS)blended WO 3 -TiO 2 and WO 3 -TiO 2 nanocomposites by a simple sol-gel and precipitation methods.…”

Pathogens with multidrug resistance have recently been responsible for widespread disease, fatalities, and economic distress. A nanomaterial with antibacterial characteristics is used to reduce the infection’s resistance. Metal-oxide nanocomposites are nanomaterials that exhibit outstanding physical and chemical characteristics. They are prime candidates for innovative functional materials with antimicrobial activity as one of their main uses. This review will summarize the current progress on the antimicrobial activity of metal-oxide nanocomposite, including widely recognized research outputs and recent findings, as these materials can overcome the limitation of the individual material due to their utterly different properties from the single materials. Additionally, it describes several metal-oxide nanocomposites that are produced using various methods for the application of antimicrobial activity, as well as the variables that can affect such activities and the main inhabitation mechanisms of this materials.

“…Pure TiO 2 and CaCO 3 nanoparticles and those containing CEO did not exhibit such inhibitory effects on their own, whether with or without CEO. Sunaryono et al [46] synthesized TiO 2 nanoparticles and assessed their antibacterial activity using the disc diffusion test. They found that pure TiO 2 exhibited a zone of inhibition of 8.94 mm for E. coli bacteria and 6.72 mm for Gram-positive bacteria such as S. aureus.…”

We explored the potential of different nanoparticles (TiO2, CaCO3, and Al2O3), considering their pure form and modified with cinnamon essential oil (CEO). These materials were characterized using various techniques, including FTIR spectroscopy, XRD analysis, TGA, and SEM. The interaction between CEO and nanoparticles changed depending on the nanoparticle type. Al2O3 nanoparticles exhibited the strongest interaction with CEO, increasing their antioxidant capacity by around 40% and their transfer of antimicrobial properties, particularly against Gram-negative bacteria. In contrast, TiO2 and CaCO3 nanoparticles showed limited interaction with CEO, resulting in lower antioxidant capacity and antimicrobial activity. Incorporating pure and CEO-modified nanoparticles into polylactic acid (PLA) films improved their mechanical and thermal properties, which are suitable for applications requiring greater strength. This research highlights the potential of metal oxide nanoparticles to enhance the antimicrobial and antioxidant capabilities of polymers. In addition, incorporating cinnamon essential oil can increase the antioxidant and antimicrobial effectiveness of the metal oxide nanoparticles and improve the mechanical and thermal properties of PLA films. Thus, these PLA films exhibit favorable characteristics for active packaging applications.

“…75 Asimismo, la incorporación de nanopartículas de TiO 2 y ZnO resulta en nanocompuestos biodegradables ampliamente utilizados en aplicaciones médicas y de embalaje, principalmente debido a sus propiedades antibacterianas y fotocatalíticas. 76 En 2014 Augustine y col., presentaron un estudio sobre la fabricación de fibras de PCL mediante electrohilado, las cuales posteriormente se reforzaron con nanopartículas de ZnO, los nanocompuestos presentaron una mejora en sus propiedades mecánicas, antibacterianas. Por lo cual, este tipo de material podría tener aplicación en la fabricación de andamios para ingeniería de tejidos.…”

Recientemente, el desarrollo de materiales derivados de fuentes renovables se ha incrementado con el objetivo de disminuir la dependencia de materias primas fósiles y así beneficiarse de ciertos monómeros renovables con aplicaciones, que abarcan desde la biomedicina, la liberación de fármacos hasta empaques para alimentos. Los poliésteres alifáticos, principalmente el ácido poliláctico (PLA) así como las polilactonas, son polímeros biodegradables y biocompatibles con aplicaciones comerciales en el área médica debido a su empleo en biomedicina. Estos materiales requieren un adecuado desempeño en propiedades mecánicas y normalmente se hace uso de nanorefuerzos para mejorar las propiedades finales. Relacionado a esto, la nanotecnología ha abierto la puerta a una serie de aplicaciones y tecnologías novedosas, por ejemplo, las nanoestructuras bio-basadas de celulosa, representan un refuerzo prometedor y ampliamente usado en matrices poliméricas debido a las propiedades, mecánicas, térmicas y biodegradables que puede llegar a aportar a los polímeros. Por otro lado, las nanopartículas de TiO2 también son empleadas como refuerzo debido a sus aplicaciones como pigmento de bajo costo y alta efectividad, su gran área superficial proporcionando propiedades únicas como efectividad en la protección UV que pueden mejorar las propiedades físicas y mecánicas de los materiales poliméricos.
