“…These were then evaluated further for antibacterial and photocatalytic activity. The results reported by patil et al in 2022 showed that metal oxides nanoparticles have better antibacterial activity and photocatalytic potential over aqueous leaves extract [43]. The leaves mostly contain triterpenoids as shown in Table 1 which include nimbin and its derivatives, gedunin and its derivatives, salannin and its derivatives, zafaral, nimbolides, nimocinol, nimonol, lupeo, isomeldenin.…”

Azadirachta indica (neem) can be considered as “Nature’s Chemist” due to its therapeutic, pharmaceutical, agro and medicinal properties. Neem tree is the most researched tree so far and has proven to be the most prospect target for the future drug discoveries. Its bioactivity has been associated with vast richness in phytochemicals whereas the terpenoids are the major medicinal components. Terpenoids are classified into different categories which display a wide range of biological activities. This article reviews the terpenoids reported in different parts of neem tree, classes, structures, their usage and application in modern medicine.

“…Owing to the phytochemical property, the semispherical shape occupied the majority of the TiO 2 nanoparticles attached to it, which appeared as a larger grain size [27]. The impure phytochemicals formed a layer over the TiO 2 surface and fused the nanoparticles resulting in semispherical shapes [28,29]. The polycrystalline nature of larger ZnO particles may be facilitated by the presence of a layered zinc hydroxide phase.…”

Rhodamine B (RhB)'s photocatalytic activity was enhanced through the green chemical synthesis of metal oxide nanoparticles (ZnO and TiO2). To produce nanoparticles, zinc nitrate hexahydrate and titanium tetra-isopropoxide precursors were hydrothermally generated using extracts from Vachellia hebeclada. These synthesised nanoparticles were then calcined at high temperatures. Variations in several parameters, including their effects on the crystal size and morphological properties of nanoparticles, were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transforms infrared spectroscopy analysis (FTIR), and UV-vis spectroscopy. With ZnO and 26.9% with TiO2 nanoparticles, the photocatalytic efficiency of RhB degradation under ultraviolet light illumination was 56.9% within 180 minutes. The reaction rate of the ZnO pseudo-first-order kinetics was the highest (0.017 min− 1) while the reaction rate of the TiO2 nanoparticles was the slowest (0.005 min− 1). The driving force for the separation of photo-excited charge carriers is taken away by the reduced photocatalytic activity of mixed-phase TiO2 particles. ZnO nanoparticles with photocatalytic applications can be produced in an environmentally friendly manner through green nano-production. According to these findings, V. hebeclada extract-mediated synthesis of ZnO and TiO2 nanoparticles may have potential applications in the photocatalytic degradation of organic pollutants like RhB. However, additional research is required to improve the synthesis procedure and investigate the effectiveness of these nanoparticles in actual wastewater treatment applications.

“…Table summarizes the latest literature on ex situ biological synthesis of NPs using plant extracts. Biologically formed NPs on textiles are playing pivotal roles due to their reliability, consistency, and robustness in the resulting functional products. , The NPs on the textiles formed by in situ and ex situ processes may affect certain properties and performances of the products. Most of the NPs are employed in the development of antimicrobial and healthcare textiles through textile finishing processes.…”

Tremendous progress has been made in developing highly efficient cutting-edge materials and textile surfaces by applying a wide range of nanostructures during the past few years. Due to their extraordinary and attractive features, metal and metal oxide nanoparticles (NPs) have introduced prominent novel antimicrobial, photocatalytic, stain repellence, fire retardant, and UV protective functions on textile surfaces. Unfortunately, their conventional syntheses based on physicochemical procedures often require energy-intensive processes and toxic chemicals, bringing environmental and human safety concerns. To address these issues, the latest approaches based on the biological production of NPs on polymeric material surfaces are currently being pursued. In this perspective, we present a systematic and comprehensive summary of the biological in situ and ex situ formation of metallic NPs on the surfaces of textiles and fibers. A detailed and insightful discussion on the ex situ and in situ mechanisms of nanoparticle formation from chemical compounds derived from plants and fungi is also provided. Finally, critical research gaps are identified, and prospects for efficient and sustainable nanofinishing technologies for textile surfaces using biological chemicals are provided.
