Nanoparticle drug delivery systems are engineered technologies that use nanoparticles for the targeted delivery and controlled release of therapeutic agents. A nano meter is a unit of measure equal to one-billionth of a meter, or three to five atoms across. 1. Research programs on nanoparticles and nanotechnol-ogy around the world suggest different strengths have developed in various countries, a fact that would sug-gest the need of international collaboration (Siegel et al., 1999; Roco, 1998). Three classes of nanofertilizers have been proposed: 1. nanoscale fertilizer (nanoparticles which contain nu- trients), 2. nanoscale additives (traditional fertilizers with na- noscale additives), and Nanotechnology. The technology promises scientific advancement in many sectors such as medicine, consumer products, energy, materials and manufacturing. This article is about nanotechnology and its applications in different fields. ZnO nanoparticles damage digestion, although it was not clear whether the toxicity was due to the high Zn dose achieved with nanoparticles or to the ZnO nanoparticles themselves. nanoparticles and nanofibers have possible applications to use as biosensors. 07/20/2021 / Mike Adams. A fascinating exploration based on the idea that nanotechnology is a very much older concept than we think. Furthermore, " smart packaging ", through which biological changes occurring in the food are detected is also one of the significant applications of Nanotechnology. Nanotechnology is a field that incorporates the studies related to nanosized particles, their function and behavior with respect to different systems.
