Développement de microcapteurs électrochimiques pour l'analyse en phase liquide

Abstract : The chemical and biological analysis techniques require the low cost development of reliable chemical sensors. In this context, the chemical field effect transistors ChemFETs and the microelectrodes offer innovating solutions but it involves an optimized interface between microtechnology, biology and chemistry. During this thesis, we have developed techniques allowing to couple chemical agents with silicon. Two approaches were studied, both based on the polymer use. First approach was centred on the encapsulation techniques development with realization of analysis microcuves and micro-canals in PDMS. The bacterial activity monitoring with pH-ISFETs was optimized within the framework study of the lactobacillus acidophilolus. The second approach relies on ChemFETs adaptation and gold microelectrodes to ions detection such as potassium and sodium. The photolithography technique allows us to make ionosensible layers using PSX (polysiloxane) in order to realize ion detection
