Low-energy biomarker detection through charge-based impedance measurements

Mihai Adrian Ionescu, Junrui Zhang, Marco Mazza

A novel approach for the detection of biomarkers in aqueous condition via differential impedance is presented. The binding of biomarkers onto functionalized inter-digital electrodes induces a change in the sensor impedance, both in its real and imaginary c ...

Design, development, and validation of an in-situ biosensor array for metabolite monitoring of cell cultures

Giovanni De Micheli, Sandro Carrara, Jacopo Olivo, Cristina Boero, Marco Mazza, Maria Antonietta Casulli, Lorenzo Foglia

Conventional pharmaceutical processes involving cell culture growth are generally taken under control with expensive and long laboratory tests performed by direct sampling to evaluate quality. This traditional and well-established approach is just partiall ...

Electrical modeling and design of a wafer-level package for MEM resonators

Mihai Adrian Ionescu, Anja Skrivervik, Julien Perruisseau-Carrier, Marco Mazza

This paper presents the electrical design and characterization of a wafer-level, or 0-level, package for micro-electromechanical resonators. We start by identifying the requirements on the electrical parasitics of a packaged resonator, derived from an anal ...
