TLDR
In this paper, a general classification of nanomaterials based on their dimensionality, shape, and composition is presented, including nanoparticles, nanotubes, and nanofilms, which can be made of single elements such as metals or carbon, or multiple elements, such as metal oxides or composites.Abstract:
In this chapter, we present a general classification of nanomaterials based on their dimensionality, shape, and composition. According to their dimensionality, nanomaterials include nanoparticles, nanotubes, and nanofilms. Nanomaterials can be made of single elements, such as metals or carbon, or multiple elements, such as metal oxides or composites. We review the most used types of nanomaterials up to date showing examples of their morphologies. The physicochemical properties of a material in nanoform can be very different from its bulk counterpart, depending not only on the type of materials, but on its size, shape, and functionalization. We discuss the most important physicochemical properties of nanomaterials, among which are morphology, dispersability, crystalline phase, melting temperature, and magnetic properties.read more

Nanoparticle Uptake by Plants: Beneficial or Detrimental?
Ivan Pacheco,Cristina Buzea +1 more
TL;DR: In this paper, the authors show that nanoparticles of many materials are already shown to be toxic to humans and animals; therefore nanoparticle uptake by plants may pose serious safety concerns, and the overall negative effects due to accumulation of nanoparticles in soil and plants might overshadow the limited beneficial aspects on some plants.
