Overview

The Espiña Research Group is dedicated to overcome some of the most challenging issue0073 in the water environment, making responsible use of original applied research on environmental nanotechnologies. The group develops and applies nanotechnology solutions for the safe and sustainable use of water resources.

Currently, we are looking for a Postdoctoral Researcher to join the group under the HARMONY project.

Job Duties

The job duties will be the following:

• Develop, characterise, test and validate biosensors based on cell receptors for marine biotoxins.
• Produce and/or isolate cell receptors, purify and characterise.
• Integrate cell receptors in microfluidic devices.
• Optimise and full characterise biosensor performance (e.g., LOD, LOQ, dynamic range, matrix effect).
• Collaborate with multidisciplinary teams with expertise in biosensors, marine biotoxins, microsystems and microfabrication technology, surface chemistry, and microfluidics.
• Produce several technical and scientific documentation as well as day-to-day management of work planning.
