Nanoparticles Before Nanotechnology By víctor puntes, josep saldaña cavallé
Paperback: $22.80
Ships in 3-5 business days.
We are glad to present another NanoWiki compilation, following 'Balancing the promises' and 'Engines On'. This year we chose the subject of Nanoparticles Before Nanotechnology simply because we were... More > suspicious that nanoparticles are too often, in scientific and non-scientific circles, perceived as invented, while we think they should be understood as discovered. Nanomaterials are claimed to be so new that people become scared. However, before nanotechnology, one can find nanoparticles in the works of both nature and Man, although they passed unnoticed by us until recently. The origin of nanoparticles in nature is basically i) biogenic, ii) geogenic (and also at the bio-inorganic interface), or iii) cosmogenic, while the nanoparticles produced by men come unintentionally from origins as burning wood and oil or unnoticed in crafted stuff such as cosmetics and colored glass and ceramics. http://nanowiki.info< Less

Biosynthesis of copper nanoparticles and their antimicrobial activity By Dr.Bharat Makwana, Dr.Pratik Dave, Parth Parikh
Paperback: $14.97
Ships in 3-5 business days.
Development of green nanotechnology is generating interest of researchers toward ecofriendly biosynthesis of nanoparticles. Biomolecules present in plant extracts can be used to reduce metal ions to... More > nanoparticles in a single-step green synthesis process. This biogenic reduction of metal ion to base metal is quite rapid, readily conducted at room temperature and pressure, and easily scaled up. In this study, biosynthesis of stable copper nanoparticles were done using datura meta leaf extract. These biosynthesized Cu nanoparticles were characterized by UV/Vis-spectroscopy, Particle size analyzer (PSA), Transmission electron mictroscopy (TEM), Energy dispersive X-ray Analysis (EDX),Fourier transform infrared spectroscopy (FTIR). Thus, this method can be used for rapid and ecofriendly biosynthesis of stable copper nanoparticles.Synthesis mediated by plant extracts is environmentally benign.< Less
Label-free Optical Detection of Viruses and Nanoparticles By Anirban Mitra

In his thesis, the author explored optical methods to detect, quantify and characterize nanoparticles and viruses < 100 nm in size on a single particle basis, label-free and in real-time. The... More > methods are based on optical interferometry, where the signal obtained from a single nanoparticle is proportional to the amplitude of the light scattered from the particle, rather than intensity. This results in weaker size dependence of the signal than for a technique that measures light scattering intensity, and therefore enables detection of smaller particles.< Less
Microparticles and nanoparticles based vaccine/antigen carriers in fish By Truptimayee Behera, Priyabrat Swain

Fish vaccinology faces similar problems that are encountered in vaccine design for human and mammals, as they are considered to be very important in reducing economic losses in pisciculture caused... More > due to diseases. For some diseases, vaccine developments are required as protection levels are still inadequate. The key to solve this challenge might lie in the designing more efficacious vaccine delivery systems and adjuvants. However, there is a paucity of published information on adjuvants/antigen carriers for fishes. This promoted to write a book on different microparticles, nanoparticles and liposome based antigen carriers for fish.< Less

Nanobacteria (calcifying nanoparticles, nanobes, nanobacterium) are mysterious particles that have spurred one of the biggest controversies in modern microbiology. Nanobacteria were discovered as... More > cell culture contaminants more than 25 years ago. They are not members of Eubacteria or Archaea, but form an entity of their own that may be of primordial origin. Nevertheless, the literature and evidence on the role of nanobacteria in oral diseases is at a rather hypothetical stage with scarce studies both in-vitro and in-vivo to culminate sufficient reliable evidence. At this mini-book we will try to introduce nanobacteria to dental practitioners and discuss their role in oral diseases.< Less
