Nanosensors are miniature sensors in nanosystems technology with which physical quantities can be measured. They are manufactured using lithographic or semiconductor-based nanoelectronics processes and are only a few square millimeters in size, allowing them to be used in the tightest of spaces.
Nanosensors are implemented in microsystems engineering( MEM) or nanosystems engineering (NEM) and can be used where minute forces are generated, where microparts or tissue samples are examined for their stress.
In medicine, nanosensors have a wide range of applications. They can be implanted directly under the skin of subjects using minimally invasive procedures to measure blood pressure, blood glucose, heart rate and electrocardiogram( ECG), and to study the interaction between biomolecules, tissue cells and artificial implants.
