In this work a modified glassy micro-particles glucose sensor was developed applying a new and effective procedure to anchor glucose oxidase on glassy micro particles using urea medium. The resulting sensor, in the presence of glucose, generates a color development in 60 seconds working at room temperature. The intensity of the resulting color shows a straightforward relationship with the glucose concentration in the samples tested. The resulting biosensor was tested to demonstrate its sensibility on dissolutions of glucose and honey.
