Nanotechnology is a fast-evolving discipline that already produces outstanding basic knowledge and industrial applications for the benefit of society. Whereas the first applications of nanotechnology have been developed mainly in material sciences, applications in the agriculture and food sectors are still emerging. Due to a rapid population growth there is a need to produce food and beverages in a more efficient, safe and sustainable way. Here, nanotechnology is a promising way to improve crop production, water quality, nutrition, packaging, and food security. There are actually few comprehensive reviews and clear textbooks on nanotechnology in agriculture, water, and food. In this book there are 10 chapters describing the synthesis and application of nanomaterials for health, food, and agriculture are presented. Nanomaterials with unique properties will dramatically improve agriculture and food production. Applications will include nanofertilisers to enhance plant growth and nanosensors to detect food contamination. An overall view of nanotechnology applications in agriculture, food, water, and environment are described in the first two chapters by Dasgupta et al. and Singh. Health and environmental applications of nanotechnology are presented in chapters 3-5. Shukla and Iravani review green methods to synthesize metal nanoparticles, and give applications to water purification, in chapter 3. The removal of up to 95% of contaminants by nanoparticles, nanotubes and nanostructured membranes is described by Naghdi et al. in chapter 4. Yoti et al. then review nanosensors for the detection of pathogenic bacteria in chapter 5. Those nanosensors can be used as biodiagnostics to control food and water quality. Food applications of nanoscience are presented in chapters 6 and 7 by Kuswandi and Sarkhar et al. Kuswandi explain in chapter 6 that nanomaterials can improve packaging quality and that nanosensors can detect freshness and contanimants. The use of nanoparticles to protect ingredients such as vitamins, flavours, and antimicrobials is reviewed by Sarkhar et al. in chapter 7.

Research Paper (undergraduate) from the year 2011 in the subject Chemistry - Other, Gulbarga University (Microbiology Dept), course: Ph.D, language: English, abstract: This study reports the extracellular synthesis of silver nanoparticles by Rhizopus stolonifer and its efficacy against multidrug resistant (MDR) E.coli and S.aureus isolated from Khwaja Bande Nawas Hospital, Gulbarga, Karnataka. Synthesis of silver nanoparticles (AgNPs) was carried out by using fungal filtrate of R.stolonifer and an aqueous solution of AgNO3. The characterization of AgNPs was made by UV-Visible absorption Spectroscope, Scanning Electron Microscope and Energy Dispersed Spectroscope (SEM-EDS), Transmission Electron Microscope (TEM), Fourier Transform Infrared (FTIR) spectroscopy and Atomic Force Microscope (AFM). TEM micrograph revealed the formation of spherical nanoparticles with size ranging between 3 to 20 nm. Atomic force microscopy gives the three dimensional structure of the particles. The presence of proteins was detected by FTIR spectroscopy. Three dimensional structure of AgNPs was studied by AFM. AgNPs produced by R.stolonifer gave good antibacterial activity against clinical isolates which were multidrug resistant. Here we report the efficacy of mycogenic metal nanosilver against MDR strains which is difficult through conventional chemotherapy.
