| Abstract Scope |
This study presents the development and evaluation of a novel water-based CO2 colorimetric optical sensor (WCCOS) with enhanced sensitivity, achieved through the incorporation of albumin into the sensor matrix. The major goal of this work is to improve the sensitivity of WCCOS, which relies on a pH-sensitive dye that changes color in response to varying CO2 concentrations. WCCOS samples with and without albumin were fabricated. The results demonstrate that the inclusion of albumin enhances the sensitivity of the WCCOS to CO2 due to changes in the microenvironment that improve CO2 diffusion and dye responsiveness. These findings suggest that albumin plays a beneficial role in improving the performance of WCCOS, offering a promising pathway toward more effective and robust optical gas sensing technologies for environmental and biomedical applications. |
