Nanobotics is a developing field of nanotechnology that features a nanoscale
measurement and can be anticipated to work at the nuclear, atomic, and cellular levels.
Nanobotics offers a new frontier in biomedicine, with the potential to transform
diagnostics and therapeutics through its unique ability to manipulate biological systems
at a nanoscale level. Nanobots have a carbon-based skeleton and a toolkit that includes
components such as a hole containing the medicine, a payload, a capacitor, and a
microcamera with a tail having the action of swimming. Nanobots are equipped with
special sensors that diagnose target particles and molecules inside the body. These
sensors can be used to diagnose and treat different imperative infections like cancer,
diabetes, atherosclerosis, kidney stones, etc. Nanobots can be used to deliver targeted
drugs to target areas of the body that are difficult to reach through traditional drug
delivery methods such as blood circulation. Nanobots are either powered by exogenous
energy (e.g., magnetic field, light, acoustic field, electric field, etc.) or endogenous
energy (chemical reactions energy). They have been shown to be capable of
encapsulating, transporting, and delivering therapeutic content directly to the site of
disease, improving the therapeutic effectiveness and reducing systemic adverse
reactions of toxic drugs. This chapter covers the following topics: Nano-based
nanobots for diagnostics and disease management, types of nanobots, advantages and
limitations, robotic approaches in drug delivery, biomedical applications of nanobots,
and their future prospects.
