Sensors i biosensors

Group leader: Julián Alonso Chamarro

Scope of the group
The Group of Sensors and Biosensors (GSB) is a multidisciplinary team integrated by researchers coming from different scientific fields, the main objective of which is the design and implementation of new sensing schemes and strategies directed to simplify the chemical and biochemical analysis. The accumulated interdisciplinary know-how and the technological facilities available in both the group and the UAB sphere  allows the group to move easily from the conceptual design to the fabrication of integrated (bio)analytical instrumentation for selected aplications.

Research lines
New transduction systems for chemical and biological recognition.
Characterization of Sensors and Biosensors and Analytical Applications
Technology Transfer
