“…These bands are indicative of the presence of alkyl halides, alkenes, aliphatic amines, alkanes, aliphatic nitro compounds, amides, amines phenols and alcohols. The occurrence of these groups can be attributed to the reduction of titanium isopropoxide to TiO 2 NPs which is achieved through organic source [40–43] . The transmittance maxima of TiO 2 NPs are at about 3281 cm −1 , 2940 cm −1 , 1649 cm −1 , 1531 cm −1 , 1382 cm −1 , 1041 cm −1 , and 422 cm −1 (Figure 3b).…”

Primary objective of this research was to examine the biogenic production of TiO2 NPs using Brassica juncea (L.) Czern seed and investigate the prospective uses of thus synthesized nanoparticles in the area of biomedicine. The synthesized TiO2 NPs were subjected to characterization using several analytical methods namely TEM, UV‐vis, XRD, FE‐SEM, FTIR and EDAX. The average particle size (TEM) is found to be 38 nm, exhibiting irregular shapes. The FT‐IR spectra indicated that the extract contains functional groups, such as polyphenolic, hydroxyl and carboxylic groups, which are likely responsible for formation of nanoparticles. The cytotoxicity studies of the synthesized TiO2 NPs against breast cancer cells (MCF‐7) and lung cells (A549) are shown to be dosage dependent. The inhibitory doses (IC50) were determined to be 43.98 μg/mL and 74.50 μg/mL on MCF‐7 and A549 cells, respectively. Green synthesized TiO2 NPs were assessed for antioxidant activity inhibition rate (DPPH 89.42 %). TiO2 NPs exhibited a maximal zone of inhibition of Staphylococcus aureus 23±0.20 mm against and 20±0.30 against Klebsiella pneumoniae at a concentration of 100 μg/mL, indicating strong antibacterial activity. The findings suggest Brassica juncea (L.) Czern seed encapsulated TiO2 NPs possesses excellent biological applications which can be explored for its application in pharmaceutical field.

Environmental photocatalysis of wastewater is an important application of TiO 2 nanoparticles (NPs). This paper reports the microwave-assisted green synthesis of TiO 2 NPs using the isolated extract of Permelia perleta lichen. Development of TiO 2 NPs was confirmed using Fourier transform infrared spectroscopy, X-ray diffraction analysis, scanning electron microscopy, and ultraviolet-visible (UV-Vis) spectroscopy. The acquired TiO 2 NPs were utilized as a nano photocatalyst in the degradation of acridine orange and phenol red dyes as model organic pollutants. The degradation efficiency of the developed TiO 2 NPs was evaluated using a UV-Vis spectrophotometer. We found that the acquired TiO 2 NPs had an average particle size of 30-40 nm, and the nanoparticles were somewhat agglomerated and are nonuniform in shape. The developed nano photocatalyst degraded the selected dyes efficiently, and the degradation efficiency was much better when the test sample was irradiated with UV light with a wavelength of 310 nm.

Recently, dermal infections caused by fungus have increased drastically, affecting people’s daily lives and causing embarrassment. These infections are either due to dermatophytes or non-dermatophytic fungi. Basically, three genera of dermatophytes namely Trichophyton, Microsporum and Epidermohyton are the main cause of dermatophytosis. Candida albicans is also responsible for some dermal infections as a non-dermatophytic fungus. Traditional antifungal compounds cause side effects and resistance in fungi, so better and non-toxic alternatives are needed. Now a day’s, nanotechnology is widely used in the pharmaceutical field and has proven to be a good antifungal agent. This study used TiO2 nanoparticles (NPs) against four human pathogens Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum gypseum, and Candida albicans. Green and chemical synthesis methods were used for the synthesis of TiO2 nanoparticles. In green synthesis, we used aqueous leaf extract of Pogostemon cablin Benth. The formation of TiO2 nanoparticles is confirmed by UV-visible spectroscopy, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FTIR) and X-ray Diffraction (XRD) analysis. According to XRD, the average size of chemically synthesized nanoparticles was 70.52 nm, while green synthesized nanoparticles were 71.82 nm. All the characterizations support that Pogostemon cablin aqueous extract can synthesize TiO2 nanoparticles. The minimum inhibitory concentration was determined according to the broth microdilution recommended assay. This study concluded that green synthesized TiO2 NPs showed good results against all four pathogens.
