Pollution is one of the major threats for the environment as well as society. It causes severe problems for the living organisms and can gives birth of various unknown issues. Different sources like cars, industrial belts, fossil fuels etc. are the major causes of air pollution. Different researchers are working to develop new methods to combat air pollution. In this work, a new solution is proposed to fight against air pollution. The proposed solution is based on nanotechnology which not only fight against the air pollution but, it can generate electricity using the nanostructured carbon materials. The proposed solution can be deployed in real life scenario to reduce the air pollution and produce electricity in a large scale to provide an alternate energy resource to the society.

In recent years, the interests of researchers are increased towards nanodrugs based on nanoparticles. The main direction of this work was to study the physicochemical, structural properties and stability of encapsulated nanoparticles, with the components from medicinal plants. Nanoparticles were obtained from the extract of the medicinal plant Сynara scolymus L. using a metal salt. Initial experimental data have shown that the originally obtained nanoparticles were not stable. Therefore, the nanoparticles were then stabilized with added sodium carboxymethylcellulose polysaccharide. It was found that new nanoencasulated nanoparticles with compounds from medicinal plants are very stable and can be a source of effective nanodrugs based on them.

Common methods of synthesizing metallic nanoparticles are chemical and physical. However, they are expensive and use toxic chemicals. Green synthesis is less costly and safer hence a potential alternative. Silver nanoparticles (Ag NPs) were synthesized using dichloromethane extract of Chrysanthemum cinerariaefolium and colour change from pale green to dark brown was observed. Scanning Electron Microscopy (SEM) images were faceted and others formed clusters. Transmission Electron Microscopy (TEM) images were spherical with an average size of 22.8± 17.5 nm. EDX analysis showed the nanoparticles had percentage abundance of 67.26%. Fourier-transform Infrared Spectroscopy (FTIR) analysis showed absorption bands at 3489.59 cm-1, 3217.80 cm-1, 2384.74 cm-1 , 1633.05 cm-1, 1405.08 cm-1, 1109.32 cm-1 and 505.93 cm-1. The UV-Vis analysis showed Surface Plasmon Resonance (SPR) peak at 434 nm. The nanoparticles were more active on P. aeruginosa with an MIC of 15 µg/ml while the cytotoxicity assay showed Ag NPs had an MIC of 33.33 µg/ml hence were noncytotoxic against Vero cells.
