Nanomedicine is a discipline of medicine that employs nanotechnology's knowledge and techniques to disease prevention and treatment. Nanomedicine is the use of small materials in living organisms, such as biocompatible nanoparticles and nanorobots, for diagnostics, delivery, sensing, and actuation. The increasing state of research in nanomedicine has aided in the reformulation of existing drugs and the invention of new ones. Nanotechnology in medicine causes changes in toxicity, solubility, and bioavailability profiles.
Nanosensors are platforms with a distinctive size - nanoscale in scale - that function similarly to sensors in which they detect minute particles or small amounts of something. Nanosensors are chemical or mechanical sensors that can be used to detect chemical species and nanoparticles on the nanoscale, and monitor physical characteristics such as temperature. Medical technology, precision agriculture, urban farming, plant nanobionics, prognostics and diagnostics, SERS-based sensors, and many more industrial applications all benefit from nanosensors.
