Abstract Active pharmaceutical ingredients have emerged as an environmentally undesirable element because of their widespread exploitation and consequent pollution, which has deleterious effects on living things. In the pursuit sustainable environmental remediation, biomedical applications, energy production, there been a significant focus two-dimensional materials (2D materials) owing to unique electrical, optical, structural properties. Herein, we synthesized 2D zinc oxide nanosheets (ZnO NSs) using facile practicable hydrothermal method characterized them thoroughly spectroscopic microscopic techniques. The are used efficient photocatalyst for antibiotic (herein, end-user ciprofloxacin (CIP) was model antibiotic) degradation under sunlight. It is observed that ZnO NSs photodegrade ~ 90% CIP within two hours sunlight illumination. molecular mechanism proposed based ex-situ IR analysis. Moreover, ZNO antimicrobial agent exhibit antibacterial qualities against range bacterial species, including Escherichia coli , Staphylococcus aureus MIC bacteria found be 5 μg/l 10 μg/l, respectively. Despite having biocompatible nature ZnO, as-synthesized also shown cytotoxicity types cancer cells, i.e. A549 A375. Thus, showed nontoxic nature, can exploited promising alternatives in different applications.

Fungal growth on construction materials in tropical climates can degrade aesthetics and manifestations modern historical sick buildings, affecting the health of their inhabitants. This study synthesized ZnO nanoparticles with enhanced antifungal properties using a precipitation method. Different concentrations (25%, 50%, 100%) Eichhornia crassipes aqueous extract were used Zn(NO3)2·6H2O as precursor to evaluate spectroscopic, morphological, textural, properties. X-ray diffraction confirmed hexagonal wurtzite phase crystallite sizes up 20 nm. Fourier-transform infrared spectroscopy identified absorption bands at 426, 503, 567 cm−1 for ZnO-100, ZnO-50, ZnO-25, respectively. Nitrogen physisorption indicated type II isotherm macropores fractal dimension coefficient near 2 across all concentrations. Polydispersity index analysis showed that ZnO-50 had higher PDI, indicating broader size distribution, while ZnO-25 ZnO-100 exhibited lower PDI values, reflecting uniform monodisperse particle sizes. FESEM observations revealed semi-spherical morphologies prone agglomeration, particularly ZnO-25. Antifungal tests highlighted most effective, especially against Phoma sp. an MFC/MIC ratio 78 µg/mL. Poisoned plate assays demonstrated over 50% inhibition 312 µg/mL tested fungi, outperforming commercial antifungals. The results indicate NPs E. effectively inhibit fungal materials. procedure offers practical approach improving durability building may contribute reducing risks associated exposure compounds.
