Green Nanotechnology is the study of how nanotechnology can benefit the environment, such as by using less energy during the manufacturing process, the ability to recycle products after use, and using eco-friendly materials. Nanotechnology covers the diverse area of matters at dimensions between approximately 1 to 100 nanometers.  Herbal medicines have been widely used all over the world since ancient times and have been recognized by physicians and patients for their better therapeutic value as they have fewer adverse effects as compared with modern medicines.  Phytotherapeutics need a scientific approach to deliver the components in a sustained manner to increase patient compliance and avoid repeated administration. This can be achieved by designing novel drug delivery systems (NDDS) for herbal constituents. The integration of the nanoscience as a NDDS in traditional system of medicine enriches the potential of herbal drugs for treating chronic diseases.  Ayurveda   is thousands of years old holistic system of Indian medicine. Various herbs, metals and non-metal preparations are used as medicine in Ayurveda.  This review paper opens door to a completely new dimension in herbal medicine and ayurveda using green nanotechnology.

: In this communication, very simple, low-cost and facile method for the synthesis of silver nanoparticles using Averrhoa bilimbi leaf extract is reported. Conventional methods for the synthesis of AgNPs have many disadvantages. Biosynthesis provides a cost-effective, non-toxic, and environment friendly method for the synthesis of nano particles. The biosynthesized AgNPs were characterized by UV-VIS spectroscopy, Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), X-Ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). The synthesized AgNPs showed a distinct surface Plasmon peak at 410 nm and also the colour of the solution changed to reddish brown. The TEM and SEM images revealed that the morphology of AgNPs is almost spherical with an average size of 10 to 15 nm. Crystalline nature and purity of the AgNPs were evident from the characteristic XRD pattern. XRD-analysis showed intense peaks corresponding to (111), (200), (220), (311), (222) planes of face centered cubic structure of metallic silver. FTIR was used to find out the specific functional group responsible for the reduction of silver nitrate to AgNPs. The antibacterial effect of AgNPs was determined by well diffusion method. The AgNPs showed antibacterial activities against food borne pathogens Escherichia coli and Listeria monocytogene.The antibactericidal effect increases with increase in the concentration of AgNPs. The promising results of biosynthesised AgNPs suggest its usage as an effective antibacterial agent to ensure food safety. These AgNPs can be incorporated with food package materials to prevent the attack and contamination of the food by the food borne pathogenic bacteria and hence corroborate the food safety.

It can be stated that, during germination, seeds original composition changes. During germination, and non protein amino acids also are produced, and changes in the quantity of several amino acids present in sprouts. In these changes, values of several biological proteins of sprouts also changes. During germination of seeds, composition of free fatty acids changes. Hydrolyzed free fatty acids originates from triglycerides. Ratio of the saturated fatty acids increases as compared to the ratio of the unsaturated fatty acids during the process of germination. Essential fatty acids like linoleic acids are originated from unsaturated fatty acids. Germination of seeds decreases antinutritive material and increases nutritive material. The utilization of elements such as micro and macro elements are increased owing to germination. Sprouts of several seeds contain proteins, vitamins, flavonoids, enzymes, antioxidants and isothiocyanates etc. These all contents are proved to be effective in several degenerative diseases and heart diseases.

Present research article deals with use of cheap, highly efficient, easily available, novel adsorbent, Indian Bael (Aegle marmelos) bark for adsorption of toxic dye like Malachite Green (MG) from the aqueous solution. Different parameters such as temperature, contact time, initial dye concentration, adsorbent dose, pH and effect of salt were studied and optimal experimental conditions were maintained. Batch adsorption technique was used to optimize the process parameter. Obtained result shows that with increase in the adsorbent doses and contact time percentage adsorption of MG increases while decreases with increase in temperature, dye concentration and addition of salt. The MG adsorption on Bael bark untreated, treated with nitric acid and treated with formaldehyde were 96.64%, 97.46%  and 97.39 % respectively at optimum pH 8. Adsorption data was well fitted with Langmuir and Freundlich isotherm models. Thermodynamic parameters indicate adsorption as an endothermic process with decrease in randomness.

In this report, the Nanohybrid synthesis of Chitosan/TiO₂ was executed by Liquid phase deposition technique in aqueous medium. Nanohybridizing was done in presence of PVP as the capping agent. Structural and Physico-chemical properties of the obtained Nanohybrid (CS/TiO₂) were systematically characterized by FT-IR, XRD, SEM, DLS and FL. The Prepared Nanohybrid act as a good Photocatalyst for the decoloration of Methylene blue (MB) dye under UV light illumination in aqueous phase. The result shows that Polymer (Chitosan) hybridized with TiO₂ could produce an effective Photocatalytic activity and the degree of Photocatalytic enhancement strongly depends on bonding of chitosan and TiO₂. It is attributed to the suppression of charge carrier’s recombination resulting from the interaction between chitosan and TiO₂. In addition, the Nanohybrid also proved to be an excellent antimicrobial agent against gram-positive (Bacillus) and gram-negative (E-coli) pathogens

It is always necessary to use valid, reliable and reproducible methods for the control and the monitoring of water quality. This study concerns the analysis of physico-chemical parameters of the Betwa River and correlations between these parameters in order to establish a diagnostic of water surface status of the river. To carry out the study, samples were taken on eight different sites in Vidisha district during the year of 2015. For the analysis of river water different parameters like pH, Electrical Conductivity, Total Dissolved Solids, Total Suspended Solids, Total Solids, Chloride contents, Total Alkalinity, Total Hardness, Dissolved Oxygen, Biochemical Oxygen Demand, Chemical Oxygen Demand, phosphates, nitrates, and sulphates were selected. This study revealed that there is a significant spatial variation in Total Solids, Total Suspended Solids and Chemical oxygen Demand which indicates different types of land use activities like agricultural or industrial uses. In duration of study, TS – TSS, chloride - Total alkalinity and Total hardness - Chemical Oxygen Demand were showing strong positive correlation. All parameters were under acceptable limit except TS and TSS. However it is necessary to improve and maintain the water quality of river in this area.

Renin is a hormone that controls many physiological functions in our body. Secretion of renin occurs from the Juxtaglomerular cell of the kidney. It activates the renin-angiotensin system (RAS) producing the angiotensin peptides which manage blood pressure, cell growth, apoptosis and electrolyte balanced. In this paper, molecular dynamics simulation of renin in aqueous environment has been considered. Molecular dynamics simulation has become an indispensable method for understanding the structure and biological functions of proteins. The following parameters radius of gyration, root mean square deviation, root mean square fluctuation was monitored.  It is seen from the analysis that elasticity exists in the protein and it does not act as a rigid body. Chain B is more fluctuating than chain A.

A mild and efficient solid acid catalysts were prepared from natural palygorskite collected from Karnataka and Hyderabad and compare their catalytic activities.  Modification technique used for the preparation of the catalysts are acid activation. During acid activation exchangeable cations are replaced by H⁺ ions and a part of octahedral cations are dissolving and thus creating new acid sites in the crystal. The catalytic performances of these catalysts were investigated by using the alkylation reaction. Alkylation reaction was done by treating benzene, biphenyl, naphthalene, anisole, p-Xylene and toluene with benzyl chloride in liquid phase medium. Physico chemical properties were characterized by XRD, SEM and NH₃-TPD measurements.
