nanoagents
Nanoagents are nanoscale devices or agents designed to perform specific tasks at the molecular or cellular level. They include engineered nanoparticles, DNA-based nanostructures, and synthetic molecular machines that can operate autonomously or under external guidance. In medicine, nanoagents are studied for targeted drug delivery, diagnostic imaging, and minimally invasive therapies, with the ability to recognize molecular markers, release payloads in response to stimuli, and navigate complex biological environments. In diagnostics, they can function as in vivo sensors that report on chemical or biological signals. In environmental and industrial settings, nanoagents may detect pollutants, catalyze reactions, or assist in assembling materials at small scales.
Design and operation often involve inorganic materials, polymers, lipids, or biological components. Movement and function can
