| Summary: | Glucose is an important molecule, it is responsible for providing energy to cells in our body, in human glucose appears in blood, excessive glucose levels in the blood are an indicator of diabetes mellitus, therefore it is important to measure it. To test the feasibility of photothermal techniques to measure glucose, thermal properties of glucose in aqueous solution were determined in the 0.7 to 3.2 mg/ml range. Thermal effusivity diminishes as glucose concentration increase. Obtained results show that used setups can measure glucose concentrations up to 600 μ g/ml. Full thermal characterization for water-glucose mixtures is presented in this work. |
