Nanosensors are small devices that can detect and measure biological or chemical substances at the nanoscale. There are several synonyms that can be used for the word "nanosensor", such as nanodetector, nanobiosensor, nanomechanical sensor, and nanoprobe. Nanodetectors can sense and capture individual molecules, making them useful for disease detection and environmental monitoring. Nanobiosensors detect biological molecules and can be used for medical diagnostics and drug development. Nanomechanical sensors measure the mechanical properties of materials and can be used for materials science and engineering applications. Nanoprobes can detect and manipulate molecules and structures at the nanoscale, making them useful for imaging and manipulation of biological systems.
