Synthesis of nanoparticles for biomedical applications

Metallic oxide nanoparticles: state of the art in biogenic syntheses and their mechanisms

“…One of the important aspects of nanotechnology is the possibility to produce some nanostructures via ecological and friendly ways, avoiding the addition of toxic solvents or technologically expensive processes (Mandal et al 2006;Mohanpuria et al 2008;Sinha et al 2009;Durán et al 2010a, b, Narayanan andSakthivel 2010;Arya 2010;Blanco-Andujar et al 2010;Gade et al 2010;Thakkar et al 2010;Popescu et al 2010;Durán et al 2011;Marcato and Durán 2011;Li et al 2011). In this context, the production of metallic oxide nanoparticles via biogenic synthesis is a great new step to the development of chemical materials via new nanobiotechnological pathways.…”

An experimental study on the synthesis of poly(vinyl pivalate)-based magnetic nanocomposites through suspension polymerization process

“…In addition, MPM can also undergo chemical functionalization, which enables their use as specific ligands for immunoassays, sequencing of nucleic acids, cells, microorganisms and others [40]. In the biomedical field, the polymeric materials presenting bifunctionality are commonly used in applications such as cell separation, drug delivery systems, proteins and enzymes carriers, immunology and purification of nucleic acids [41].…”

Nanosilver: new ageless and versatile biomedical therapeutic scaffold

“…Three main components, namely organic and inorganic reducing agents, capping agents or stabilizers, and metal precursors or silver salts, are used in this method (Figure 2). Hydrogen gas, 94 borohydride, 80,94,95 citrate, 96 ascorbic acid, 97 hydrazine compounds, polyol process, Tollens' reagent, N,N-dimethylformamide, and poly (ethylene glycol) (PEG)-block polymers are the reducing agents most frequently used in this method. These reductants bring about a reduction of silver ions (Ag + ) to metallic silver (Ag 0 ) followed by agglomeration into oligomeric clusters in aqueous and nonaqueous solutions.…”
