DOWNLOAD EBOOKNanotechnology is an emerging field of science. It has increased applications in diverse area for the development of new materials at nanoscale levels. Synthesis of nanoparticles using biological methods is referred as greener synthesis of nanoparticles. Green synthesis provides advancement over chemical and physical method as it is cost effective, environment friendly, and safe for human therapeutic use. Stingless bees are highly social (eusocial) insects which populated the tropical earth 65 million years ago longer than honey bees. Among the most common uses of stingless bee honey are to treat stomach disturbance, cough, tonsillitis, sore throat, stomach and intestinal ulcers, cold, disease of the mouth, mucus membrane, and as a wound dressing due to its antimicrobial activity. Stingless bees honey were used to for the green synthesis of silver nanoparticles. Antimicrobial activity of the green synthesised nanoparticles were tested used agar diffusion method against Escherichia coli (E. coli), Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Klebsiella pneumoniae. The results showed that stingless bee honey could be effectively used for the synthesis of silver nanoparticle. The synthesized silver nanoparticles shows antibacterial activity on both Gram positive and Gram negative bacteria. This biosynthesis of nanoparticles is cost efficient, pollutant free and simpler to synthesize.

DOWNLOAD EBOOKBachelor Thesis from the year 2013 in the subject Biology - Miscellaneous, grade: M.Sc., , course: Biotechnology, language: English, abstract: Research and analysis of nanoparticles (NPs) synthesis and their biological activities has been expanded significantly in the recent years. The agents used for nanoparticles (NPs) synthesis are of organic (mainly carbon) and inorganic (metal ions like silver and gold) origin (Singh et al., 2010). Among these, silver (Ag) is the most preferred NPs synthesis agent due to its reported use in medical field as best topical bactericides from ancient times (Lavanya et al., 2013). The stable silver nanoparticles had been synthesized by using soluble starch as both the reducing and stabilizing agents (Shrivastava et al., 2012). So the concern of scientific community shifted towards ecofriendly, natural and cheaper method of NPs synthesis by using microorganisms and plant extracts (Mohanpuria et al., 2008). The use of plant materials for silver nanoparticles (AgNPs) is most popular due to its potential biological activities, easy availability and faster rate of synthesis there by cutting the cost of NP's synthesis (Huang et al., 2007 and Salam et al., 2012). The nanoparticles had been clinically used for infection, vaccines and renal diseases (Malhotra et al., 2010). The plant extract of petals of herbal species like Punica granatum, Datura metel (Chandran et al., 2011) and stem extracts of Svensonia hyderobadensis (Linga et al., 2011) had been effectively used for AgNPs synthesis and investigated for their antimicrobial activities. Nanoparticles could be synthesized by various approaches like photochemical reactions in reverse micelles (Taleb et al., 1997), thermal decomposition (Esumi et al., 1990), sonochemical (Zhu et al., 2000) and microwave assisted process (Santosh et al., 2002 and Prasher et al., 2009). Nanocrystalline silver particles have found tremendous applications in the field of high sensitivity biomolecular detection and diagnostics (Schultz et al., 2000), antimicrobials and therapeutics (Rai and Yadav., 2009 and Elechiguerra et al., 2005) and micro-electronics (Gittins et al., 2000). Acacia auriculiformis A. Cunn. is an exotic species that can survive in degraded lands in Thai savanna (Badejo et al., 1998). Besides its high adaptability in degraded savanna areas, A. auriculiformis is known for its nitrogen fixation property (Sprent and Parsons, 2000) enriching macrofaunal composition (Mboukou-Kimbatsa et al., 1998), low allelopathic effects (Bernhard-Reversat et al., 1999) and ability to pump nutrients from the subsoil (Kang et al., 1993).

DOWNLOAD EBOOKDocument from the year 2017 in the subject Chemistry - Bio-chemistry, Mansoura University, language: English, abstract: Forty-two medicinal plants were collected depending on their availability on Egypt. These plant were extracted and screened for their activity towards green synthesis of AgNPs. A new modified method was used in order to screen large number of extracts in short time (high throughput screening). In this method, the synthesized nanoparticles were evaluated in using 96-well plate which is transparent to facilitate the color monitoring and easy to be read spectrophotometrically using microplate reader. The green synthesis activity by the different plant extracts was monitored and evaluated by color change and UV-Vis absorption at time intervals. Out of these 42 plants, only 3 plants viz.,Pyllanthusemblicafruits, Psidium guajava leaves and Lawsoniainermisleaves, showed high AgNPs synthetic activity. The most active plant extracts were further partitioned with ethyl acetate. The results showed that the EtOAc fraction of the three active plants showed superior AgNPs green synthesis over their remaining aqueous. Thus, chromatographic columns were used to isolate the active compounds from the EtOAc fraction of each plant. Metal nanoparticles synthesis is a leading topic of research in modern material science owing to their distinctive potential applications in the field of electronic, optoelectronic, information storage and Health care. Among the all noble metal nanoparticles, silver nanoparticles are one the main products in the field of nanotechnology which has acquired limitless attention due to their unique properties such as chemical stability, good conductivity, catalytic and most important antibacterial, antiviral and antifungal activities. Nevertheless, there is still need for economic commercially viable as well as environmentally clean synthesis route to synthesize the silver nanoparticles.
