Microbial Potential

The synthesis of nanoparticles (NP) using marine plants has been well developed. In recent years, few reports of NP synthesis use mangroves, which are used as bio plants for synthesis. In addition, mangroves are a renewable, sustainable and economical source compared to other marine organisms, so they can be explored effectively in the synthesis of green NPs (Green Synthesis). Therefore, this study reports on the biosynthesis of NP, especially silver nanoparticles (AgNPs) using mangrove extracts. NPs synthesized by this method are primarily spherical with promising anti-microbial potential. The biosynthesis of silver nanoparticles can be triggered by several compounds such as carbonyl, terpenoid, phenolic, tannin, flavonone, amine, amide, protein, pigment, alkaloid and other reducing agents in biological extracts capable of as reducing agents and capping agents. Marine bio-nanotechnology has great promise in nanomedicines, groceries, pharmaceuticals and industrial fabrics for the future.

First Time

Production of silver nanoparticles from the leaf extracts ofPimenta dioicais reported for the first time in this paper. Three different sets of leaves were utilized for the synthesis of nanoparticles—fresh, hot-air oven dried, and sun-dried. These nanoparticles were characterized using UV-Vis spectroscopy and AFM. The results were diverse in that different sizes were seen for different leaf conditions. Nanoparticles synthesized using sun-dried leaves (produced using a particular ratio (1 : 0.5) of the leaf extract sample and silver nitrate (1 mM), resp.) possessed the smallest sizes. We believe that further optimization of the current green-synthesis method would help in the production of monodispersed silver nanoparticles having great potential in treating several diseases.

Development of an ecofriendly, reliable, and rapid process for synthesis of nanoparticles using biological system is an important bulge in nanotechnology. Antioxidant potential and medicinal value of Adiantum philippense L. fascinated us to utilize it for biosynthesis of gold and silver nanoparticles (AuNPs and AgNPs). The current paper reports utility of aqueous extract of A. philippense L. fronds for the green synthesis of AuNPs and AgNPs. Effect of various parameters on synthesis of nanoparticles was monitored by UV-Vis spectrometry. Optimum conditions for AuNPs synthesis were 1 : 1 proportion of original extract at pH 11 and 5 mM tetrachloroauric acid, whereas optimum conditions for AgNPs synthesis were 1 : 1 proportion of original extract at pH 12 and 9 mM silver nitrate. Characterization of nanoparticles was done by TEM, SAED, XRD, EDS, FTIR, and DLS analyses. The results revealed that AuNPs and AgNPs were anisotropic. Monocrystalline AuNPs and polycrystalline AgNPs measured 10 to 18 nm in size. EDS and XRD analyses confirmed the presence of elemental gold and silver. FTIR analysis revealed a possible binding of extract to AuNPs through –NH2 group and to AgNPs through C=C group. These nanoparticles stabilized by a biological capping agent could further be utilized for biomedical applications.

Studies of green synthesis of nanoparticles mediated by plants extract is extensively explored and studied in recent time due to eco-friendliness, cost-effectiveness, and use a minimum amount of toxic chemicals in the process of inorganic material synthesis. In this study, the immobilization of silver nanoparticles on the surface of titanium dioxide (TiO2) was carried out using Uncaria gambier Roxb. leaf extract as a silver ion (Ag+) reducing agent. The synthesized Ag/TiO2 nanocomposite was characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), and Diffuse Reflectance Spectroscopy (DRS). The formation of silver nanoparticles was confirmed through UV-Vis spectroscopic analysis, which showed a silver surface plasmon resonance (SPR) band at 426 nm. The X-ray diffraction pattern shows that Ag can inhibit the transition of the anatase into rutile phase. The presence of Ag particles in TiO2 can increase the absorption ability from an initial wavelength of 407 nm to 438 nm. Based on the results of Rhodamin B degradation, it can be seen that Ag/TiO2 has a higher photocatalytic activity than bare TiO2 with 99% percent degradation at 120 minutes of irradiation time.

Abstract Background: The present work describes the synthesis of silver nanoparticles (AgNps) from leaf extracts of Piper betle and Jatropha curcas using a green approach. Green synthesis of nanoparticle is superior over other methods of synthesis as it is ecofriendly and cost effective. The phytochemical components in the leaf extract play a vital role in reducing the AgNO3 and hence synthesizing the silver nanoparticles. During this reduction activity, the several factors which affect the synthesis of nanoparticles were investigated and optimized according to the yield of nanoparticles. The experimental conditions investigated were pH, temperature, pressure, time of reaction, microwave radiation, UV radiation and concentration of plant extract, silver nitrate & sunlight. Satisfactory yields of silver nanoparticles synthesis from plant extract were obtained by using optimum conditions when compared to conventional synthesis of nanoparticles. The optimization parameter was later Result: A mathematical model was formulated to correlate the interactive influence of the parameters and the significant reduction. Plackett-Burman design (PBD) indicated that concentration of plant extract, concentration of silver nitrate and sunlight were the major parameters affecting the synthesis of silver nanoparticle. The mutual interactions of these variables are mapped in the design by 3 Box-Behnken design (BBD). The significant factors and their interactions in the green synthesis were examined by analysis of Variance (ANOVA). The result indicated that the BBD was a good predictive model for the experimental results. Though the plant extracts are different, the characterization of the synthesized nanoparticle after optimization of parameters showed uniform size and shape i.e. spherical shape and size of 41 nm. Conclusion: The silver nanoparticles were synthesized under different optimization parameters were uniformly shaped (spherical) and sized (41 nm) particles. The mathematical models Plackett-Burman and Box-Behnken helped in analyzing the impact of the optimization parameters.

Nanoparticles are gaining interest in biomedical applications due to its importance such as anti-bacterial, anti-fungal and anti-cancer agents. Conventional methods for the synthesis of metal nanoparticles involves toxic reagents which produce harmful by-products and are hazardous to the environment. To overcome these limitations, green synthesis of nanoparticles was established. Eco-friendly methods using plant extracts are gaining popularity due to the abundance of raw materials and the production of non-toxic by-products threatening to the environment. Moreover, the nanoparticles synthesized from the plant extract are cost-effective. In addition, nanoparticles produced by green synthesis methods produces synergetic effect where both the nanoparticles as well as the natural bioactive constituents of the plant influence the biocidal properties. Different methods namely heating in water bath, microwave oven and exposure to bright sunlight were adopted for the synthesis of silver nanoparticles. Plant extract based synthesis of silver nanoparticles was eco-friendly and shows an alternative promise in bio-medical applications and it undertakes the negative effects of synthetic drugs.

New modifications in nanoparticles changed their applications obviously. Green synthesis of nanoparticles and their biomedical utilizations have been the focus of increasing attention in recent years. Silver nanoparticles (AgNPs) demonstrated surprising effects and many advantageous features for cancer therapy. Investigations indicated the anticancer activity of AgNPs in different ways, comprising cell cycle arrest, DNA damaging and apoptosis, alteration of P53 function, up/down regulation of some important cytokine genes and so on. But some key inquiries like the ability to control the accidental effects of AgNPs, or encompassing process for parcels, which reduces the toxicological profile of nanoparticles, still remained. “Green synthesis” of nanoparticles has been shown to be a kind of approach to resolve the toxicity amounts in a range of 10-18 times. Using distinctive properties of this approach, i.e. as green synthesized silver nanoparticles (G-AgNPs), in order to raise potential therapeutic efficacy, even up to two-fold higher than cis-platin, is going to play a crucial role in cancer treatment and could be considered as a new insight in this field. The current review focuses on the antioxidant activity of G-AgNPs and potential impacts on cancer cells.
