Microneedles functionalized with aptamers for the optical detection of cortisol

matteo ecolasse

The goal of this subject is to develop a biosensing device using microneedles and aptamers to measure cortisol. That device would offer a reliable way to diagnose cortisol related medical conditions.

I am Matteo, an engineer coming from Normandy, France, and I recently started working on a collaborative project between the DPM and CEA-Leti laboratories. During different internships, I’ve sharpened my interest for fluorescent biosensing probes and microneedles, it motivated me to work on a project combining both. The development of efficient, ready-to-use, and portable devices still being a great challenge, in particular for medical applications, that subject possible results greatly motivate me.  The cross and multidisciplinary environment of Arcane, which offers opportunities for pertinent and new ideas, will, I hope, be a catalyst for my PhD. For the future I would like to working in research and development environment, hopefully in the industry.
