Biosynthesis of nanoparticles and silver nanoparticles

Abstract

In this century, the development of nanotechnology is projected to be the establishment of a technological evolutionary of this modern era. Recently, nanotechnology is one of the most active subjects of substantial research in modern material sciences and hence metal nanoparticles have a great scientific interest because of their unique optoelectronic and physicochemical properties with applications in diverse areas such as electronics, catalysis, drug delivery, or sensing. Nanotechnology provides an understanding on fundamental properties of objects at the atomic, molecular, and supramolecular levels. Besides, nanotechnology also leads an alternative technological pathway for the exploration and revolution of biological entities, whereas biology provides role models and biosynthetic constituents to nanotechnology. The findings of this review are important to provide an alternative for the green synthesis of silver nanoparticles. It showed more cost-effective and environmental friendly application as well as easier for large production, with relation to the properties of silver nanoparticles as antimicrobial, can be served well as an alternative antiseptic agent in various fields. Typically, silver nanoparticles are smaller than 100 nm and consist of about 20-15,000 silver atoms. Due to the attractive physical and chemical properties of silver at the nanoscale, the development of silver nanoparticles is expanding in recent years and is nowadays significant for consumer and medical products.

Silver nano fabrication using leaf disc of Passiflora foetida Linn

“…3. The complete process is divided into three phases as activation, nucleation and growth phase (Keat et al 2015). The prevalent good example for synthesis of AgNps using Fig.…”

Biofabricación de nanopartículas de metales usando células vegetales o extractos de plantas

“…It has a series de NPs de metales, aunque también se encuentran resultados acerca de la biosíntesis de nanomateriales como el grafeno (Gurunathan et al, 2014). Se dispone de una serie de revisiones de literatura que señalan muchos casos específicos, incluyendo las especies vegetales utilizadas para la biofabricación de NPs, así como los elementos transformados a NPs (Iravani, 2011;Baker et al, 2013;Rai y Yadav, 2013;Pardha-Saradhi et al, 2014b;Ahmed and Ikram, 2015;Keat et al, 2015).…”

“…El proceso de fabricación biológica puede ocurrir de forma intracelular (Haverkamp and Marshall 2008), extracelular (Li et al, 2011) o inclusive ex planta por medio de los exudados radicales (Pardha-Saradhi et al, 2014a). Básicamente lo que se lleva a cabo para la biofabricación de NPs es poner en contacto una solución con 1 a 2 mM de iones de un metal con un cultivo celular, órgano, semillas o planta completa, de tal forma que se of reviews of literature that indicate many specific cases, including plant species used for biomanufacturing of NPs, as well as elements transformed to NPs (Iravani, 2011;Baker et al, 2013;Rai and Yadav, 2013;PardhaSaradhi et al, 2014b;Ahmed and Ikram, 2015;Keat et al, 2015).…”

Silver and Silver Chloride Nanoparticles and their Anti-Tick Activity: a Mini Review

“…However, it is known from the literature, 23,[35][36][37][38]55 that Gram-negative bacteria are effectively eliminated by Ag 0 nanoparticles. Then, the antibacterial studies regarding tick-borne infections are an open area for research.…”

“…One important nanostructure is the silver nanoparticles (Ag 0 ) or also nanoparticles of the silver cloride (AgCl). The silver nanoparticles biogenically synthesized are widely studied by many research groups in the world [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] and Ag 0 nanoparticles were quite efficient against Aedes aegypti.…”
