Increased Surface Area: Nanomaterials provide a larger surface area for interaction with the pH-sensitive material, which enhances the sensor's performance. Enhanced Sensitivity: Due to their small size and high reactivity, nanomaterials can detect minute changes in pH levels, making them highly sensitive. Rapid Response Time: The high surface area and reactivity of nanomaterials allow for quicker response times, which is crucial in applications requiring real-time monitoring. Custom Functionalization: Nanomaterials can be functionalized with specific chemical groups to target particular pH ranges, improving selectivity.
