EXASENS

Sputum characterization using SiGe high-frequency monolithic sensors

Objective

There is a growing demand for “all-electrical” sensor platform in conjunction with microfluidic techniques for biosensing in order to circumvent the existing problems of optical sensors, therefore, eventually leading to more compact lab-on-chip devices. SiGe high-frequency circuits offer the platform for all-electrical biosensing along with front-end electronics on the same chip. For tuberculosis detection, characterization of sputum using IHP SiGe BiCMOS high-frequency sensor is the main objective of the project.

IHP's Contribution

Designing of the monolithic BiCMOS sensor and the read-out circuit is the main contribution of IHP in the project. IHP along with University of Potsdam, has already established the first high-frequency dielectric immunosensor for creatinine. Polymer based microfluidic system was integrated with the BiCMOS high-frequency chips for particle concentration detection in aqueous solution.

Funding

This project receives funding by the Federal Ministry of Education and Research (BMBF) in the funding program "InnoProfile Transfer" with funding number 13N13862.
