Description: A nanostructured sensor is a device that incorporates nanostructures to enhance its performance in detecting various physical or chemical magnitudes. These nanostructures, which can be nanoparticles, nanowires, or nanotubes, allow for greater sensitivity and selectivity compared to conventional sensors. Due to their small size, nanostructured sensors can interact with molecules at the atomic level, giving them the ability to detect minimal changes in the environment. Furthermore, their integration into Internet of Things (IoT) systems enables real-time data collection and transmission, facilitating monitoring and control of processes across various applications. The versatility of these sensors makes them ideal for use in fields such as healthcare, environmental monitoring, industry, and security, where precision and speed in detection are crucial. In summary, nanostructured sensors represent a significant evolution in sensor technology, providing innovative and efficient solutions for data collection in an increasingly connected world.
History: Research on nanostructures began to gain momentum in the 1980s when scientists started exploring the unique properties of materials at the nanoscale. In 1991, the discovery of carbon nanotubes by Sumio Iijima opened new possibilities for their application in sensors. Over the years, various techniques have been developed for the fabrication of nanostructured sensors, enabling their integration into real-time monitoring and control systems.
Uses: Nanostructured sensors are used in a wide range of applications, including toxic gas detection, air quality monitoring, disease detection through biomarkers, and industrial process control. Their high sensitivity makes them ideal for applications where precise and rapid measurements are required.
Examples: An example of a nanostructured sensor is the carbon nanotube-based gas sensor, which can detect gas concentrations in the air at very low levels. Another example is the use of gold nanoparticles in biosensors for disease detection, such as cancer, through specific biomarkers.
