What Are the Challenges in Achieving High Sensitivity and Low Noise?
One of the main challenges in achieving high sensitivity and low noise is the inherent trade-off between these two parameters. Enhancing sensitivity often involves increasing the interaction between the sensor and the target analyte, which can also increase noise levels. Balancing these factors requires careful design and optimization of the nanomaterials and device architectures. Moreover, maintaining high sensitivity and low noise in real-world environments, which are often subject to various interferences, remains a significant challenge.
