Article Synopsis
- The study focuses on creating a non-invasive glucose biosensor that uses saliva and a smartphone camera, improving accessibility for diabetes detection.
- The sensor works by changing color when it reacts with glucose in saliva, with a quick response time of 20 seconds and good sensitivity.
- Calibration shows reliable glucose detection across different subjects, indicating its potential for widespread use in areas with limited healthcare resources, as it only requires a low-cost test strip and a smartphone.

In our present study, we developed an optical biosensor for direct determination of salivary glucose by using immobilized glucose oxidase enzyme on filter paper strip (specific activity 1.4 U/strip) and then reacting it with synthetic glucose samples in presence of co-immobilized color pH indicator. The filter paper changed color based on concentration of glucose in reaction media and hence, by scanning this color change (using RGB profiling) through an office scanner and open source image processing software (GIMP) the concentration of glucose in the reaction medium could be deduced.
