Welcome to the Crespo research group at the Royal Institute of Technology situated in the lovely Stockholm city! During 2017, we have been recruiting outstanding researchers in early and mid-career as well as motivated Ph.D. students. Would you like to be the next one?

What is our interest? We develop fundamental electrochemical and optical concepts to be integrated into ‘chemical sensors’ aiming to solve current problems in healthcare, environment, wellness, food among others.

One of our papers on wearable all-solid-state sensors has been highlighted as the front cover for the prestigious journal TrAC, Trends in Analytical Chemistry. The review covers areas such as why wearable all-solid-state sensors mainly detects ions in sweat out of all bodily fluids as well as the sensors current position within analytical chemistry today. For more information, check out the review here.
