About ECsens

As a spin-off of the University of Twente, ECsens is a high-tech research start-up focusing on Lab-on-a-Chip platforms for liquid biopsies. With unique experience in nanoscale electrical engineering, sample transport and surface functionalization, we develop extremely sensitive and selective, plug ’n play health care technology. Our mission:

To enhance treatment efficacy with smarter screening tools.


Our surface engineering ensures minimal fouling and maximal affinity, reducing false positives and false negatives.


Nanofabricated electrochemical sensors award the sensitivity to detect biomarkers down to the single nanoparticle level.


Smart sample handling drives analytes to sensors,  increasing throughput by orders of magnitude for quick and reliable readout.

What we offer

Development of liquid biopsy-based integrated sensor platforms for various applications is our main focus. Our technology is uniquely capable of detecting and quantifying (single) nano- and microparticles in a range of complex media, either passively or targeted using specific recognition elements. If you have a custom application in mind whereby our skillset and access to advanced cleanroom technology could be of use, we welcome you to challenge us to satisfy your exact needs.


We are developing versatile technology and high-performance functionalization, aimed at specific quantification of various submicron analytes in various bodily fluids.


Our technology is capable of analysis of dispersions of (sub)micron particles in fluids of any kind, not limited to biological applications.


Specializing in thin-film nanoscale patterning and (unconventional) microfluidics, we can support the development of varying integrated systems.


We have the experience necessary to bring a range of functionalities to numerous types of surfaces, ranging from polymers to ceramics and metal alloys. Moreover, we have access to the required surface characterization equipment to optimize your coatings.


Several positions are available at ECsens for canditates in various stages of their career: from students to senior team members. For a recently granted EU research project (UNICORN Dx), 5 postdoc positions are available worldwide.

Internship or thesis (e.g. with affiliate research groups at UT)

At ECsens, we are always excited to welcome students -some of our most valuable know-how comes from these bright young minds!

Typically our applicants are from Electrical Engineering, Applied Physics or Nanotechnology. We also had many Biomedical Engineering and Biomedical Laboratory students. But we’re also keen on meeting students from Industrial Design, Industrial Engineering, (Business) Information Technology and especially any other program – we love to learn from fresh perspectives!

For your bachelor or master thesis assignment, we can collaborate with research groups at UT, e.g. NanoElectronics, BioElectronics, Medical Cell BioPhysics or AMBER.

If you just contact us through LinkedIn or send a (preferably short) message to student@ecsens.com, we’ll create a position especially for you!

University of Twente –
Applied Microfluidics for BioEngineering Research

This project aims at developing an innovative sensing platform using a multi-modal detection mechanism for the detection of biomarkers at the single-particle level. Your role in this broad project will focus on the sample preparation steps and the device integration. You will develop an integrated microfluidic platform to support a “sample-in/answer-out” paradigm for a point-of-care solution integrating adequate sensing modalities (developed by other partners).

Johannes Kepler Universtät Linz – NanoElectronics

The Nanoelectronics group is looking for two PostDocs to work with us on an EU project that develops a biosensor platform for virus detection.

The platform will be based on an approach that uses single-entity biosensing by combining DC electrochemical measurements and AC detection at GHz frequencies.

The successful candidate will focus on the implementation of the Surface GHz Resonance detector.

Both detection modalities will be combined in purpose-made lithographically fabricated nanodevices.
