In this paper we report on the fabrication and characterization of a potentiometric biosensor for the detection of triglycerides, based on lipase impregnated mesoporous silicon matrices. Prototypes, realized on 1x1 cm n+-type silicon wafers, show a very high enzymatic activity. Moreover the properties of these biosensors have been stable in a several months time interval, clearly showing their advantages with respect to traditional triglycerides detection systems.

Abstract
In this paper we report on the fabrication and characterization of a potentiometric biosensor for the detection of triglycerides, based on lipase impregnated mesoporous silicon matrices. Prototypes, realized on 1x1 cm n+-type silicon wafers, show a very high enzymatic activity. Moreover the properties of these biosensors have been stable in a several months time interval, clearly showing their advantages with respect to traditional triglycerides detection systems.
