Materials for Nanosensors
2.1 Introduction
When constructing a house, several materials are required, such as cement,
concrete, bricks, tiles, iron and steel bars, ooring materials, and so on.
Similarly, a large variety of materials is used to fabricate nanosensors. In fact,
numerous! But some materials like nanoparticles (NPs), quantum dots (QDs),
carbon nanotubes, inorganic nanowires, thin lms, and nanoporous materi-
als nd widespread usage in many nanosensors. One repeatedly stumbles
across their names while perusing nanosensor literature.
Low-dimensional nanometer-sized materials and systems have dened a
new research area
