Background: Chronic obstructive pulmonary disease is a leading cause of morbidity and mortality worldwide. Effective infection control in rehabilitation units essential but remains insufficiently studied. This study investigated bacterial contamination, the distribution species, effectiveness antimicrobial strategies center. Methods: Surface swab sampling ZnO-based were employed to assess contamination The samples cultured, species identified. Results: Bacterial on six key surfaces was initially high (over 500 CFUs/100 cm2) significantly reduced after application ZnO tape these surfaces. antibacterial rates exceeded 80% one week using nanoparticle suspension; however, some surfaces, declined even three weeks. These findings suggest that protection should be renewed weekly maintain its efficacy. Conclusions: solution effectively center, underscoring need for regular disinfection innovative strategies.

Abstract Background The synthesis of nanomaterials has traditionally relied on methods that pose significant environmental risks due to high-energy demands, hazardous chemicals, and waste generation. For instance, conventional techniques such as chemical vapor deposition the sol–gel process are known for their consumption production toxic by-products. This context emphasizes importance sustainability in nanomaterial synthesis, leading a shift toward more eco-friendly integrate principles green chemistry lessen influence environment. transition addresses harmful effects associated with traditional approaches promotes use renewable resources, biomass agricultural waste, production. Main body review focuses sustainable utilize biomass, natural extracts. These reduce energy consumption, limit generation, enhance recyclability, supporting nanocircular economy. Various strategies, including hydrothermal solvents, examined effectiveness producing desirable properties. also highlights broad applications these catalysis, sensing, biomedical fields, storage. Despite considerable advancements, field faces ongoing challenges related scalability, comprehensive impact assessments, need performance optimization. Conclusion presents opportunities advancing technologies reducing footprint While remain, continued research innovation promise further progress scalable efficient methods, driving development an environmentally conscious approach synthesis.
