Synthesis, characterization and pharmacological activities of silver nanoparticles using leaves extract of turmeric plant

In present manuscript describes synthesis of silver nanoparticles using turmeric leaves extract, traditional turmeric is a common spice that comes from the root of Curcuma longa, chemical called curcumin. Turmeric has a warm, bitter taste and is frequently used to flavor or color curry powders, mustards, butters, and cheeses. People commonly use turmeric for osteoarthritis, hay fever, depression, high cholesterol, liver disease, itching. There is also no good evidence to support using turmeric for COVID-19. Synthesis of silver nanoparticles AgNO powder was dissolved in distilled water to prepare 10 mM AgNO stock 3 3 solution from which different composition prepared. The AgNO solutions were mixed with urmeric plants 3 t leaves extract in equal proportion in flask. The flask was wrapped with an aluminum foil and was then heated in a water bath at 50-60 C for 2 hours. The synthesis of nanoparticles, which was confirmed by UVSpectra and TEM. UV-Vis spectra and visual observation showed that the color of the fresh leaf extractsof Vinca rosea turned into brownish yellow, respectively, after treatment with silver. In addition, TEM analysis confirmed that AgNO solutions for all concentrations produced ilver nanoparticles and their average size 3 s was less than 20 nm. Turmeric plants extract of fresh leaves can be used as bioreducing agents, drug resistant strains, toxic nature towards microbial agents, play an important role in nanoscience and nanotechnology, particularly in nanomedicine and potential applications in cancer diagnosis and therapy.

Green synthesis of silicon dioxide nanoparticles and L arginine@silicon dioxide nano- composites using cellulose of Zizyphus Spina-Christi along with biological evaluation

The recent research focused on the green synthesis of silicon dioxide nanoparticles, SiO2@Cellulose of Zizyphus Spina-Christi nanocomposites, and L-Arginine@SiO2@Cellulose of Zizyphus Spina-Christi nanocomposites using cellulose of Zizyphus Spina-Christi as a new green polymeric surfactant. The structures of nanoparticles and nanocomposites were characterized by different spectroscopy and microscopy techniques. Nanoparticles and nanocomposites were utilized to determine the concentration of chromium, cadmium, and lead in COVID-19 patients using double-vortex-ultrasonic assisted surfactant enhanced dispersive liquid-liquid microextraction. Mean recoveries of chromium, cadmium, and lead were obtained in the range of 86-98% with relative standard deviations below 4%. The advantages of the proposed method are green and novel polymer surfactant with low detection limit. Finally, antibacterial activities were investigated. The maximum inhibition zone of L-Arginine@SiO2@Cellulose of Zizyphus Spina-Christi nanocomposites was obtained for StaphylococcusAureus (21.9..0.4 mm). L-Arginine@SiO2@Cellulose of Zizyphus Spina-Christi nanocomposites have low cytotoxicity against MCF-7 cancer cells. These results indicated the potential ability of L-Arginine@SiO2@Cellulose of Zizyphus Spina-Christi nanocomposites in the determination of metal concentrations in biological samples along with good antibacterial properties and cytotoxic properties.

Nanotechnology is the applied science of making and manipulating matter on a small scale in the range of 1-100 nm. The application of nanotechnology, particularly in vaccine science, has developed rapidly in recent years, leading to the birth of "nanovasinology". Nanotechnology is playing an increasingly important role in vaccine development, thanks to nanocarrier-based delivery systems that offer the possibility of enhancing cellular and humoral immune responses. Nanoparticle-based vaccine applications can protect vaccines from premature spoilage, increase stability, and have good adjuvant properties. NPs, with their biodegradable, minimally toxic properties, provide effective and alternative platforms to traditional vaccine methods that can be used to deliver various antigens to specific tissues and organs. Virus-like particles, liposomes, ISCOMs, polymeric inorganic nanoparticles, and emulsions;out-of-scale materials are attracting attention as potential delivery vehicles that can both stabilize vaccine antigens and act as adjuvants. The composition of the nanoparticle material plays an important role in the transport and pharmacokinetic properties of the nanoparticles, the rate of release and cellular uptake, biodegradability and biocompatibility. It is thought that nanoparticular vaccines may guide the development of vaccines for many diseases in the future, including rapidly emerging pandemics such as COVID -19 and cancers that cannot be controlled by vaccination. This review;It provides information on the physical properties of nanoparticles and nanoparticle vaccine types and reviews studies using nanoparticle-based vaccine technologies.
