“…The main peak of h=27.42°matches the (110) crystallographic plane of rutile form of TiO 2 nanoparticles, indicating that the nanoparticles structure produced is only rutile form and not of anatase or brookite form (Roopan et al 2012). The formation of TiO 2 NPs synthesized using N. arbor-tristis leaves extract was supported by XRD peaks at 25.3°, 37.8°, 47.9, 54.5°, 62.8°, 69.5°, and 75.1°which indexed the planes 101, 004, 200, 105, 204, 116, and 215, respectively, of the cubic face-centered titanium dioxide (Sundrarajan and Gowri 2011).…”

Titanium dioxide nanoparticles (TiO2 NPs) are considered to be among the best photocatalytic materials due to their long-term thermodynamic stability, strong oxidizing power, and relative non-toxicity. Nano-preparations with TiO2 NPs are currently under investigation as novel treatments for acne vulgaris, recurrent condyloma acuminata, atopic dermatitis, hyperpigmented skin lesions, and other non-dermatologic diseases. The present study was to investigate the acaricidal and larvicidal activity of synthesized TiO2 NPs utilizing leaf aqueous extract of Mangifera indica L. (Anacardiaceae) against hematophagous parasites. The anti-parasitic activity of TiO2 NPs against the larvae of Rhipicephalus (Boophilus) microplus, Hyalomma anatolicum anatolicum and Haemaphysalis bispinosa (Acari: Ixodidae), fourth instar larvae of Anopheles subpictus, and Culex quinquefasciatus (Diptera: Culicidae) were assessed. The green synthesized TiO2 NPs were analyzed by UV-Vis, FTIR, X-ray diffraction (XRD), AFM, SEM, and TEM. The XRD analysis of synthesized TiO2 NPs revealed the dominant peak at 2θ value of 27.81 which matched the 110 crystallographic plane of the rutile structure indicating the crystal structure. The FTIR spectra exhibited a prominent peak at 3,448 cm(-1) and showed OH stretching due to the alcoholic group, and the OH group may act as a capping agent. The SEM images of TiO2 NPs displayed spherical, oval in shape, individual, and some in aggregates. Characterization of the synthesized TiO2 NPs using AFM offered three-dimensional visualization and uneven surface morphology. The TEM micrograph showed agglomerates, round and slight elongation with an average size of 30 ± 5 nm. The maximum efficacy was observed in synthesized TiO2 NPs against the larvae of R. microplus, Hyalomma anatolicum anatolicum, Haemaphysalis bispinosa, A. subpictus, and Culex quinquefasciatus with LC50 value of 28.56, 33.17, 23.81, 5.84, and 4.34 mg/L, respectively. In the present study, a novel, simple, and eco-friendly approach has been suggested to control blood-feeding parasites.

“…For example, Roopan et al have found that Annona squamosa peel could be used to effectively synthesize TiO 2 nanoparticles [256], while Nyctanthes arbor-tristis leaf extracts have been found to produce spherical particles ranging in size from 100 to 150 nm [257] and Eclipta prostrata leaf extracts can produce particles ranging in size from 36 to 68 nm [258,259]. Velayutham et al have used a Catharanthus roseus leaf extract to biologically synthesize TiO 2 nanoparticles.…”

Nanotechnology is the creation, manipulation and use of materials at the nanometre size scale (1 to 100 nm). At this size scale there are significant differences in many material properties that are normally not seen in the same materials at larger scales. Although nanoscale materials can be produced using a variety of traditional physical and chemical processes, it is now possible to biologically synthesize materials via environment-friendly green chemistry based techniques. In recent years, the convergence between nanotechnology and biology has created the new field of nanobiotechnology that incorporates the use of biological entities such as actinomycetes algae, bacteria, fungi, viruses, yeasts, and plants in a number of biochemical and biophysical processes. The biological synthesis via nanobiotechnology processes have a significant potential to boost nanoparticles production without the use of harsh, toxic, and expensive chemicals commonly used in conventional physical and chemical processes. The aim of this review is to provide an overview of recent trends in synthesizing nanoparticles via biological entities and their potential applications.

“…Titanium dioxide (TiO 2 ) is naturally formed and usually used as a white pigment and paints, food colorants, papers, plastics, inks, and toothpastes because it is nontoxic, it is also considered as low-cost metal due to its wide existence in nature. Due to its ability to absorb UV light and high refractive index, TiO 2 nanoparticles have been used to synthesize nanoparticles with many plants like Nyctan, arbortristis extract, leaf extract of Catharanthus roseus, Eclipta prostrate aqueous leaf extract, and peel extract of Annona squamosa L. 13,14 .…”

Titanium nanoparticles (TiNPs) have been synthesized due to its certain characteristics that are expected like non-toxic, eco-friendly, and bioactivity. In this study, the researchers used Banana Peels Extract (BPE) with titanium dioxide to prepare new nanoparticles which are never carried before. These nanoparticles were biologically synthesized using an aqueous solution of banana peel extract as a bioreductant. The novel TiNPs were successfully prepared and characterized using Ultraviolet-Visible Spectroscopy (UV-VIS), Atomic Force Microscopy (AFM), X-Ray Diffractometer (XRD), and examined its antimicrobial activity against several pathogenic bacteria as well as insecticidal agent against Musca domestica. The instrumental analysis confirms the presence of TiNPs with average diameter: 88.45 nm and volume 31.5 nm as resulted by AFM and XRD respectively, while the bioactivity exam to TiNPs shows inhibitory effect against several pathogenic bacteria, as well as it cause a high mortality percentage against three larval stages of house fly.
