Abstract

The development of nanocomposites for sensor applications represents a significant breakthrough in materials science and engineering, driven by the unique properties of nanomaterials. Nanocomposites, which combine nanoparticles with polymers or other matrices, exhibit enhanced mechanical, electrical, and thermal properties, making them highly suitable for various sensing applications. The integration of nanoparticles, such as metal oxide, carbon nanotubes, and graphene, into a composite framework can dramatically increase sensitivity and selectivity, enabling the detection of low concentrations of target analytes. Recent advancements in nanocomposite materials have led to innovations in gas sensors, biosensors, and environmental monitoring devices. These materials can be tailored to optimize their performance for specific sensing tasks, allowing for rapid response times and improved accuracy. Various studies have highlighted the advantages of integrating nanoparticles into polymer matrices to create materials that exhibit superior sensitivity, selectivity, and stability compared to conventional sensors. One prominent area of research involves metal oxide nanoparticles, such as zinc oxide (ZnO) and tin dioxide (SnO2), which have been extensively studied for gas sensing applications. These materials benefit from a high surface-to-volume ratio, facilitating increased interactions with target gases. Graphene-based nanocomposites have also emerged as a key focus area due to their exceptional electrical and thermal properties. It is found that graphene oxide incorporated into polymer matrices can significantly improve the sensitivity and selectivity of biosensors, enabling the detection of biomolecules at lower concentrations. The integration of nanocomposite sensors into real-world applications, such as wearable devices and smart environmental systems, remains a challenge. Issues related to scalability, cost-effectiveness, and integration with existing technologies require further investigation to translate laboratory successes into practical solutions. Additionally, the focus on real-world applications, such as wearable devices and environmental monitoring, positions this research at the forefront of addressing practical challenges in sensor technology, ultimately contributing to enhanced safety, health, and environmental monitoring solutions. The development of nanocomposites for sensor applications combines advanced nanotechnology with material science, enabling highly sensitive, selective, and efficient sensors. These innovations address critical challenges across diverse fields, paving the way for smarter, cost-effective, and scalable solutions, and ultimately driving progress in healthcare, environmental monitoring, and industrial automation.
