The present work describes the eco-friendly synthesis of silver nanoparticles using dried fruit extract of C. carandas. The synthesized AgNPs were characterized by UV-Vis analysis, FTIR, XRD, SEM and TEM with histogram. The TEM image of the precipitated solid phase of AgNPs showed in the range of 23 ± 2 nm in size. Further, the catalytic degradation on crystal violet dye in the presence of C. carandas dried fruit extract and AgNPs was also studied.

Inorganic and Nano-Metal Chemistry

This book chapter scrutinizes the total synthesis of natural products extricate from fruits and vegetables and its biological activities allied to certain diseases. Generally, natural products are extricated from plants and their products. Which render nutrition, phytochemicals, vitamins, fibers, and minerals etc.., these are manifest numerous biological activities such as antioxidant, antibacterial, anti-inflammatory, and antifungal activity etc., hostile to chronic diseases like cancer, Alzheimer's, heart disease, arthritis, and asthma etc., at a certain level, and gift with good health. Natural products are present in the free form or associated with glycosides in little quantity, sometimes difficult to isolated in pure form. Therefore, total synthesis plays a major role in the current engrossment, synthesis and its study allied to biological activities. © Springer International Publishing AG, part of Springer Nature 2018.

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.

In recent era researchers are mainly focused on silver (Ag) and silver doped nanoparticles due to its vast area of applications which are effectively acts against the microbial activity. Silver nanoparticles (AgNP’s) were one of the metal nanoparticles which have high activity against various diseases causing pathogens to safeguard the environment. However, there is increasing concern related to biological impacts by the use of silver doped nanoparticles on a large scale. The synthesized silver nanoparticles were doped with other chemical reagents by using various physio-chemical methods. The stability of silver nanoparticles was governed by morphological features, capping agents and organic molecules. This review article briefs about the synthesis of silver doped nanoparticles using different methods and their antimicrobial activity. © 2014, Springer Science+Business Media New York.

In this paper, we have established for the first time, the terrific efficiency of aqueous extract of agricultural waste dried peel of sugar apple (Annona squamosa) in the rapid synthesis of stable SnO2 nanoparticles. In topical years, the deployment of secondary metabolites from plant extract has emerged as a novel technology for the synthesis of various nanoparticles. In this paper, we have studied the potential of SnO2 nanoparticles assembly using agricultural waste source for the first time. The synthesized nanoparticles were characterized and confirmed as SnO2 nanoparticles by using UV-visible spectroscopy, XRD, and TEM analysis. The motivation of this study was to examine cytotoxicity study of SnO2 nanoparticles against hepatocellular carcinoma cell line (HepG2). SnO2 nanoparticles inhibited the cell proliferation in a dose- and time-dependent manner with an IC50 value of 148 μg/mL. The treated cells showed an altered morphology with increasing concentrations of SnO2 nanoparticles. Our result shows that the SnO2 nanoparticles exhibit moderate cytotoxicity towards the hepatocellular carcinoma (HepG2) at tested concentrations.

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.

Biosynthetic trends and future aspects of bimetallic nanoparticles and its medicinal applications

Inflammation plays an important role in various diseases with high prevalence within populations such as rheumatoid arthritis, ulcer, atherosclerosis, and asthma. Many drugs are available in the market for inflammatory diseases. They exhibit several unwanted side effects to humans. Therefore, alternative treatments with safer compounds are needed.Carissa carandasplant is used in traditional medicinal system for its various diseases curing property. In the present study, we examined the anti-inflammatory effects of dried fruit methanol extract on carrageenan-induced hind paw edema in rats.C. carandaswas defatted with petroleum ether, followed by methanol extraction. The methanol extracts of the dried fruits ofCarissa carandaswere given orally to the experimental rats caused significant activity (P≤0.05) when compared with the control group. The maximum inhibition of paw edema was found to be in Group V, that is, 76.12% with inhibition of paw volume in a dose-dependent manner. The anti-inflammatory activity of the methanol extract of the dried fruits shows that the presence of potential constituents present in this extract may provide assistance in the drug discovery process. The phytochemical compounds of the extract were screened by GC-MS analysis and it was found that 11 compounds are present in methanol extract of dried fruits ofCarissa carandas.
