pH is an important physiological parameter within organisms, playing a crucial role in functional activities cells and tissues. Among various sensing methods, optical fiber sensors have gained wide attention due to their unique advantages. However, current silica fiber-based face some challenges such as weak biocompatibility, low biological safety, complex or unstable surface modification. Herein, we develop what believe be novel sensor based on CdSe/ZnS quantum dots-doped polymer microprobe (POF MP) grown at the end of using free radical photopolymerization process, which has advantages significant compactness, high flexibility, good easy functionalization, structural stability safety. Moreover, size POF MP are controllable, highly for applications requiring specific probe sizes those used special terrains. The proposed demonstrated sensitivity 0.18097/pH range from 4.5 9.0, while it exhibits linear correlation between fluorescence intensity value ( R 2 = 0.99448) reversibility reusability. This offers promising solution monitoring environments, contributing advancements biosensing, microenvironment monitoring, potential therapeutic applications.
