Luminescent TiO2 nanoparticles synthesized from Mollugo Oppositifolia and Trianthema Portulacastrum for dye degradation, antimicrobial and antioxidant properties
In modern times, nanoparticles have materialized as indispensable things in contemporary medicine, with a variety of uses in clinical, drug and gene conveyance. In the present study, TiO2 nanoparticles (NPs) prepared from the leaf extracts of Mollugooppositifolia and Trianthema portulacastrum were compared with the chemical TiO2-NPs for antibacterial and antioxidant activities and environment-friendly nature through various tools like the UV-visible, X-ray diffraction with the aid of other analytical techniques like HR-TEM, Fourier transform infrared (FT-IR) and photoluminescence spectroscopic techniques. The morphology of green TiO2-NPs is found to be spherical, which is supported by HR-TEM images. FT-IR analyses and X-ray diffraction data ensure that the polycrystalline characters of TiO2-NPs alike to the presence of metal oxide. TiO2-NPs showed a possible photocatalytic activity for the ruin of acid black 1 dye after disclosure to sunlight. The chemical and green methods of TiO2-NPs have acid black 1 dye decomposition rates of 86.66% and 94.33%, respectively. The synthesized TiO2-NPs are also assessed for antimicrobial and antioxidant activities. Green TiO2-NPs exhibit antibacterial activity against Pseudomonas aeruginosa (17 + 0.56 mm) and Staphylococcus aureus (16 + 0.24 mm) at concentrations as low as 100 μL. The green TiO2-NPs showed high inhibition of DPPH I radical (50 μg/m) at 95.17 ± 21. Therefore, TiO2-NPs represent eco-friendly properties that aid in the degradation of dyes due to their antioxidant activity.
期刊介绍：
Luminescence provides a forum for the publication of original scientific papers, short communications, technical notes and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence and phosphorescence. Luminescence publishes papers on assays and analytical methods, instrumentation, mechanistic and synthetic studies, basic biology and chemistry.
