Several cheaper raw materials are becoming increasingly popular in nanotechnology:
Silica: Abundant and inexpensive, silica can be used to create a variety of nanostructures, including nanotubes and nanoparticles. Carbon-Based Materials: Materials like graphene and carbon nanotubes can be derived from graphite, which is relatively cheap. Cellulose: Derived from plants, cellulose nanofibers are a sustainable and cost-effective option for various applications. Clay: Natural clay minerals can be used to create nanoclays, which are useful for making nanocomposites.
