Recent development in the green synthesis of titanium dioxide nanoparticles using plant-based biomolecules for environmental and antimicrobial applications

Silica nanoparticles as novel sustainable approach for plant growth and crop protection

“…Extracts such as bioactive polyphenols, proteins, phenolic acids, alkaloids, sugars, terpenoids etc., are responsible for reduction during NPs development (Figure 2). The major sustaining aspect for physical properties of the synthesized NPs is the difference in quantity and conformation of these reducing bio agents with aqueous metal ions (Aslam et al, 2021). During the process, the plant and waste extract and the metal salt suspension are mixed perfectly at room temperature (Siddiqi et al, 2018).…”

Physico-chemical characteristics and cytotoxicity evaluation of CuO and TiO2 nanoparticles biosynthesized using extracts of Mucuna pruriens utilis seeds

“…Extracts of multitudinous plants and plant parts (leaf, root, stem, bark, flower and fruits) have previously been employed in phytogenic synthesis of various metallic nanoparticles including copper oxide (CuO) and titanium dioxide (TiO 2 ) ( Ahmad et al., 2012 ; Sunny et al., 2022 ). The bioactive compounds (phytochemicals) in the extracts serve as natural reducing and capping agents to functionalize and stabilize the synthesized metal nanoparticles in order to prevent their agglomeration ( Aslam et al., 2021 ). Plants including Magnolia kobus ( Lee et al., 2013 ), Syzygium aromaticum (Clove) ( Subhankari and Nayak, 2013 ), Euphorbia nivulia (Common milk hedge) ( Valodkar et al., 2011 ), Sterculia urens (Karaya gum) ( Padil and Černík, 2013 ), and many others have been used in this regard.…”

Synthesis, Characterization, and Photocatalytic Activities of Graphene Oxide/metal Oxides Nanocomposites: A Review

“…It can be used to determine analyte concentrations or the chemical conversion of a component. The range of reflection and absorption is measured so that the nanocomposites visible and ultraviolet optical activity is defined (Aslam et al, 2021). The characteristics of various metal nanoparticles ranging from 2 to 10 nm could be based on light wavelengths of between 300 and 800 nm.…”
