Chapter 3

Smart Nanomaterials*

Abstract

The topic of “smart” nanotechnology branches into a variety of fields, from nanomedicine to electronics. Various “smart” nanomaterials, their response mechanism under different stimuli, some examples of accepted synthesis, and some of their applications are being examined in this chapter. The core types of nanomaterials are hydrogels (network of hydrophobic polymer chains), polymer brushes (e.g., extracellular polysaccharides on bacterial surfaces), carbon nanotubes (stiffest and strongest fibers known in addition to excellent conductivity), and cellulose (e.g., cellulose acetate for films). Responses vary based on the kind of nanoparticles (e.g., pH-responsive nanomaterials, light-responsive nanomaterials, ...
