Introduction to Nano-sized Devices
Nano-sized devices are
engineered structures that operate at the nanometer scale, typically ranging from 1 to 100 nanometers. These devices leverage the unique properties of materials at the nanoscale, such as increased surface area and quantum effects, to perform specific functions that are not possible with larger-scale devices.
What are Nano-sized Devices?
Nano-sized devices are tiny machines or structures designed to interact with their environment at the molecular or atomic level. These devices can include
nanorobots, nanosensors, and
nanomaterials with specific functionalities. They are capable of performing tasks such as drug delivery, environmental monitoring, and even
repairing cells in the human body.
