Welcome to Nanoionics, part of the MESA+ Institute of Nanotechnology and of the Faculty of Science and Technology at the University of Twente, the Netherlands.

We are a recently founded, internationally oriented group, aiming to enhance the fundamental understanding of electrostatics and electron transfer in liquid and across the liquid/solid interface, and to explore new concepts for fluidic devices based on this new understanding.

Recent and current research topics include for example electrochemical detection of single molecules in nanofluidic devices, high frequency CMOS-based nanosensors, the nanophysics of ionic liquids, nanoscale electrocatalysis and electrochemical scanning probe methods.

Our experimental tools, which are largely dictated by the intrinsic nanometer scale of the systems that we study, include scanning probes, highly sensitive electronics, and lithography-based microfabrication.

FluidFM people

Our postdoctoral researcher, Dr. Jos Quist, will tell you about his interesting and challenging research on using FluidFM to study single living cell. Read more about his interview here https://cytosurge.com/blog/cytosurge-news-2/post/fluidfm-people-jos-quist-16

Around the world and beyond

For the NI winter group outing, the NI group decided to kick off the holiday season with an Escape Room event. Our brave group members embarked on amazing journeys, not only around the world, but even to Mars! Success rates vary: while part of the group managed to blaze around the world in an all-time record time, others wandered and lost their way (and may even be drifting around aimlessly in space). Importantly, there was much merriment and mirth.

The new record holders

Lost in space

P.S. Should you encounter on of our lost group members on your travel, please contact us and and let us know they are safe.

Cutting-edge paper

Cecilia contributes to a groundbreaking paper in Nature Nanotechnology on using high-frequency impedance spectroscopy to enable label-free detection of a broad range of analytes. The paper, a collaboration with our colleagues at NXP Semiconductors (NL), U. Udine (IT) and 3PRI-Bioscience, Wageningen (NL), combines fundamental exploratory experiments on prototypical systems, detailed quantitative simulations, and imaging of cancer cells. Yes, it is fun.

Play for your life

In the greatest-of-all-time group outing, many of us have shown high performance to survive in the jungle by climbing from ‘Tree2Tree’ during NI 2015 summer group outing. Some (albeit not all) admit that it was scary.

Before the carnage.

Sahana explains to Stanley why it’ll be so much fun. He thinks about it, but he’s not quite convinced yet.

So young, yet so much to lose…

Ab shows us how to do it right.

Wouter gets it…

… although his tips get Minmin into a funny situation (and vice-versa, it has later been recorded).

This is why I didn’t choose Letters for my PhD – it might have been too easy.

The following pic might look like Zinaida but it is a stunt double. We would never ask this from a group member, given the >10 m height. Really.

In conclusion: we’ll never do this again, right? Right???

And there was much merriment.
