Cocos nucifera is one of the most adaptable products which possess several protein fractions such as albumins, globulins, prolamines, glutelins 1 and 2 which were found and reported. Since C. nucifera was rich in nutritional value, it has wide medicinal applications. In this manuscript, we have reviewed on the anti-inflammatory, antioxidant, antimicrobial, antimalarial, leishmanicidal, and insecticidal activity. Also C. nucifera act as a low cost agricultural waste which was widely used in the preparation of nanoparticles: in this review, we have also focused on silver, gold, aluminum oxide, and doped nanoparticles like europium doped yttrium oxide nanoparticles. © 2015 Elsevier B.V.

AbstractNature and nanotechnology have not yet achieved a lucid correlation in the field of science but together they have exhibited immense potential towards the advancement and modification in future science and technology. Due to the unique properties of nanomaterials like nanoparticles gained considerable importance. Among all the nanoparticles, zinc oxide (ZnO NPs) are greatly utilized in sensors, catalysis, bioscience, etc. Antimicrobial activity by ZnO NPs had more attention by the implementation of nanotechnology for the preparation of ZnO NPs. At present, antimicrobial activity of ZnO NPs using Aegle marmelos (A. marmelos) leaves extract was done. The ZnO NPs subjected to UV-Vis, FT-IR, XRD, SEM and TEM analysis. The presence of phenolic group in extract has the capacity to form ZnO NPs and act as stabilizing agent. Every 5 min interval ZnO NPs was formed which recorded by UV-Vis spectrophotometer. The SEM analysis displayed a fine spherical ZnO NPs and EDAX report showed that the existence of zinc and oxygen in the ratio of 30.51% and 69.49%. The antimicrobial activity of ZnO NPs has high percentage inhibition against A. niger at 1000 ppm. Till now, no research carryout on A. marmelos mediated ZnO NPs and applications towards antimicrobial activity.

The eco-friendly synthesis of nanoparticles through green route from plant extracts have renowned a wide range of application in the field of modern science, due to increased drug efficacy and less toxicity in the nanosized mediated drug delivery model. In the present study, our research groups have biosynthesized the stable and cost effective copper oxide nanoparticles (CuO NPs) from the leaves of (Ormocarpum cochinchinense) O. cochinchinense. The synthesis of crystalline CuO NPs from the leaf extract of O. cochinchinense were confirmed by various analytical techniques like UV-Visible Spectroscopy (UV-Vis), Fourier-Transform Infrared Spectroscopy (FT-IR), X-Ray Diffractometer (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Selected Area Electron Diffraction (SAED) pattern. Further the synthesized CuO NPs were screened for anticancer activity on human colon cancer cell lines (HCT-116) by MTT (3-(4,5-dimethyl-2-tiazolyl)-2,5-diphenyl-2-tetrazolium bromide) assay. The obtained result inferred that the synthesized CuO NPs demonstrated high anticancer cytotoxicity on human colon cancer cell lines (HCT-116) with IC50 value of 40μgmL-1 were discussed briefly in this manuscript.

In this era, researchers have mainly concentrated on green synthesis of nanoparticles which is rapid, nontoxic, ecofriendly, reproducible and less cost when compared to the chemical and physical methods. Phytochemical reduction of AgNO3 to Ag NPs using root bark extracts of Catunaregum spinosa (C. spinosa) is reported in this manuscript. The resulting bio-reduced Silver nanoparticles (Ag NPs) were analyzed by UV–Visible Spectroscopy, FT-IR, XRD, TEM, Zeta potential and EDAX. Preparation of Ag NPs was identified by transformation of color from white to brown with maximum absorption at 442 nm due to Surface Plasmon Resonance. Crystalline studies by XRD inferred that the biosynthesized Ag NPs were crystalline in nature and further morphological studies revealed that the particles were spherically agglomerated with size ranging from 33 ± 2 nm. Moreover, the green synthesized Ag NPs were subjected for the degradation of toxic Amaranth dye using photoreactor exactly at 365 nm and pseudo first order kinetics were also stated the rate of degradation reaction were identified to be − K = 0.932 which provides significant results showing 94.07% degradation of azo grouped dye. © 2016 Elsevier B.V.

In recent decades, several scientists focused their process towards nanoparticles synthesis by using various sustainable approaches. Cocos nucifera (C. nucifera) was one of the versatile trees in tropical regions which also can act as a thrust quencher in all over the world. Cocos nucifera coir was one of the waste by-products in all coconut-refining industries and with the help C. nucifera coir, Palladium nanoparticles (Pd NPs) were synthesized. Green-synthesized spherical-shape Pd NPs were over layered by secondary metabolites from C. nucifera coir extract and with an average particle size of 62 ± 2 nm, which were confirmed by morphological analysis. Eco-friendly mediated Pd NPs were further subjected to several biological applications like larvicidal against Aedes aegypti (A. aegypti) and anti-feedent, ovicidal, and oviposition deterrent against agricultural pest Callasobruchus maculates (C. maculates) and compared with C. nuciferacoir methanolic extract, which results in LC50 value of 288.88 ppm and LC90 value of 483.06 ppm using LSD-Tukey’s test against dengue vector (A. aegypti). Cocos nucifera coir methanolic extract shows significant output while compared with Pd NPs towards anti-feedent assays; ovicidal activity and oviposition deterrent were discussed here. © 2016 Informa UK Limited, trading as Taylor & Francis Group.

Most of researcher focused their research towards synthesize of nanoparticles by the method of applied chemical method which was one of the costliest method. We have focused cheapest and simplest method for the synthesizing of lead nanoparticles (Pb-NPs) using cocos nucifera L extract. The methanolic extract of cocos nucifera L was efficiently used as a reducing agent for synthesizing Pb-NPs. On treatment of lead acetate with cocos nucifera coir extracts, stable Pb-NPs were formed. The synthesized Pb-NPs were further confirmed by UV-visible spectroscopy, X-ray diffraction (XRD), Transmission electron microscope (TEM) and Energy Dispersive (EDAX) analysis. The secondary metabolites present in methanolic extract which can mainly act as a reducing and capping agents for the formation of Pb-NPs were identified by GC-MS. Anti-microbial activity for Pb-NPs against four pathogenic strain's such as Staphylococcus aureus, Escheria coli, Staphylococcus epidermis and Bacillus subtilis. Result states that Pb-NPs size was 47 nm and also shows good activity against S. aureus. Further we report on photocatalytic absorption of malachite green dye processed in short UV wavelength at 254 nm. UV spectral analysis showed peak absorbance at 613 nm with special reference to the excitation of surfaces plasmon vibration by Pb-NPs.

Recently, in all over the world, nanotechnology plays a major role in various applications. Most of the researchers focused their work on bimetallic nanoparticles due to their several modes or mechanisms of synthesis such as chemical, physical, and biosynthesis methods. These nanoparticles are of great interest due to their enormous applications and catalytic activities. Currently, syntheses of bimetallic nanoparticles using different sources of natural products are focused due to their advantage of being nontoxic to human and environment. To our knowledge, there is no report on the review of bimetallic nanoparticles and their medicinal applications. Taking this fact into account, we discussed the various synthesizing methods of bimetallic nanoparticles and their application related to biology. © 2014 Springer-Verlag.
