“…FTIR peaks around 504, 554, 758 and 827 cm -1 were due to MnO NPs [36][37][38][39][40]. However, peaks around 603 (R-CH group), 922 (-C-O bond), 1220 (CH 2 group or C-O stretching), 1319, 1368 (C-O vibrations), 1475 (bending frequency methylene group), 1618 (aromatic C = C bond stretching), 1707 (C = O stretching vibrations), 2925 (-C = C bond) and 3393 (OH bond) cm -1 were observed mainly due to the presence of eugenol, caryophyllene, humulene and eugenol acetate in CE [41][42][43]. FTIR characterization of CE revealed similar peaks around 551, 600, 918, 1226, 1368, 1447, 1615, 1729, and 2936 cm -1 which were due to presence of these moieties (Supplementary figure S4b ).…”

Manganese oxide (MnO) NPs are widely used in contaminant sensing, drug delivery, data storage, catalysis and biomedical imaging. Green synthesis of NPs is important due to increased concern of environmental pollution. Green chemistry based synthesis of NPs is preferred due to its ecofriendly nature. In this study, MnO NPs of different sizes were synthesized in aqueous medium using clove, i.e., Syzygium aromaticum extract (CE) as reducing and stabilizing agents. These NPs were used for the electrochemical sensing of p-nitrophenol (PNP). The synthesis of MnO NPs was over in 30 min. MnO NPs of different sizes were obtained by varying metal ion concentration, metal ion volume ratio, CE concentration, CE volume ratio, and incubation temperature. Selectively, *4 nm MnO NPs were used for electrochemical sensing of paranitrophenol. The MnO NPs modified gold electrodes detected PNP with good sensitivity, 0.16 lA lM -1 cm 2 . The limit of PNP detection was 15.65 lM. The MnO NPs prepared using CE based green chemistry approach is useful for PNP sensing. These NPs can also be useful for various in vivo applications in which the NPs come in human contact.

“…Nanoparticle synthesis furthermore carried out using Szyygium aromaticum bud extract, Murraya koenigii leaf extract. This synthesis is owing to the natural reducing agent eugenol and could be carbazoles present in the extracts correspondingly [26,27]. Biosynthesis of gold nanoparticles utilizing the leaf extract of Mirabilis jalapa was explicated [28].…”

The uprising in materials science has been hosted by previous few decades. There has been a substantial research interest in the area of using particulate systems to accomplish various approaches. The conception or synthesis of material with nanometer-scale precision (nanoparticles), by means of material science, is nanotechnology. Nanoparticles are defined as particulate dispersal or solid particles, with a size in the range of 1-100 nm.This review intends to present biosynthesis and application of nanoparticles in minutiae. Here, we discussed different synthesis methods, i.e. chemical, physical and biogenic synthesis of nanoparticles. The potential come together between nanotechnology and biological science is enormous. Realistic biologics depends on units that have nanoscale dimensions (proteins, viruses, molecular motors, extra cellular matrix). Our major dictum is to focus the various facet of synthesis of nanoparticles, characterization, and its imperative application by giving accent on biogenic synthesis of nanoparticles.

“…For example from Hordeum vulgare (monocotyledonous) and Rumex acetosa (dicotyledonous) plants, iron oxide nanoparticles were produced [15]. In addition to that, Diopyros kaki leaf extract is known for the green production of platinum nano crystals [16], gold nanocrystals using Gnidia glauca flower extract [17], silver and gold nano crystals from Aloe Vera extract [18] and clove [19] have been reported.…”
