Diabetes mellitus is a group of long-term metabolic pathologies that occur when glucose levels in the body cannot be adequately controlled due to insulin deficiency. There is currently no cure, so its treatment is essential for the huge amount of the individuals that suffer from it. The part of the population who needs exogenous insulin administration for its management must monitor blood glucose levels several times per day. The devices that exist today for such monitoring are mainly classified as invasive and minimally invasive. The former provides a value of the blood glucose level from a sample taken at the time, and the latter performs a continuous measurement of the blood glucose level. On the other hand, different technologies are being investigated that allow non-invasive measurements of blood glucose levels. Among these is microwave technology, which has been used in different investigations for monitoring biomolecules such as glucose. Based on this information and on studies that relate dielectric properties such as permittivity with glucose concentration, the nBio research group developed several experiments to build a microwave sensor that could determine variations in glucose concentration by changes in permittivity. The experiments were first performed in water solutions containing glucose and then in human plasma and on the tongue of patients. The obtained results showed that the sensor was very sensitive but not very selective. This project proposes an experimental protocol for broadband RF measurements in cell culture, which would serve as an intermediate step between the measurements performed in water with glucose, and in human plasma and volunteers, to better understand the dielectric response in a living medium, such as cell culture, and the influence of glucose on it. For this purpose, two experimental procedures were developed to understand the effect of cell density and the effect of the glucose and its dynamics in cell culture. These two factors were found to influence the dielectric response of the culture. However, for future experiments, it is suggested to study in more detail the influence of the coaxial cable and the effects at the microscopic level caused by the interaction of cells with glucose. Additionally, it is also recommended to further standardize the parameters of the experiment to be able to make a more detailed analysis of the results
