Nanotechnology focuses on materials with a length scale of 1 to 100 nm, where traditional disciplines as physics, chemistry and engineering converge. It is the ability to control the structure of matter on that small scale, that allows us to develop novel materials and products, which will impact a wide range of application areas.
Nanotechnology is beyond doubt the technology of the future and is prospected to offer novel solutions to the grand challenges we face today!
Nanotechnology is beyond doubt the technology of the future and is prospected to offer novel solutions to the grand challenges we face today: (green) energy harvesting, information technology, homeland security, clean water, sufficient food production, but also new avenues towards treatment of human diseases, such as cancer, neurodegenerative diseases, diabetes, etc.
Saxion is the first University of Applied Sciences in the Netherlands with a research group in Nanotechnology. Its activities embody Saxion’s vision of a strong profile in Living Technology.
The NanoPhysics research group, headed by dr.ir. Cas Damen, aims to bridge the gap between fundamental technology developed at research centres, such as the MESA+ institute at the University of Twente, and applications based on societal challenges. The focus is on implementation of chip-based technologies. Specifically, the following technologies are being studied:
- Integrated photonics
- Micro-electromechanical Systems (MEMS)
The Nanotechnology research group emerged from a joint initiative with Mesa+ Institute for Nanotechnology, University of Twente.
The Nanotechnology research group serves as a meeting point for students, staff, researchers and industry.
Nanotechnology service centre
The Nanotechnology research group serves as a meeting point for students, staff, researchers and industry. The department acts as a low-threshold service center, where students and industry can use nanotechnology-specific equipment and can work jointly on advanced research projects. A total project cycle is implemented, from conceptualization through product patent to development. Students of the nanotechnology study program are actively encouraged to contribute.
More information on this project will follow soon.
Foundries (aluminium, steel and iron) use moulds, in which the metal is poured in in liquid form, in order to take on the shape of the mould. These molds are produced with sand and a so-called binder. Usually this binder is an organic compound, which often is toxic. Especially in case of metal casting this results in the release of highly toxic substances in gaseous form. In this project GietechGo we aim to introduce inorganic binders in three different foundries in the provinces of Overijssel and Gelderland in the Netherlands. Read more
Sensors based on nanotechnology
Sensors based on nanotechnology are considered being a technology that can contribute to the quality of and reduction of costs in our health care. Due to their extreme sensitivity, this type of sensors is capable of giving a diagnose quickly yet accurately, using only a small quantity of sample from blood, saliva, breath of urine. This creates additional possibilities next to existing, often more extensive analysis techniques. Read more
Saxion is partner in this project, headed by Fontys. More information will follow soon.
The project runs from 1st September 2017 until 31st August 2021.

Sensor System for Early Detection of Veterinary Diseases
Many (veterinary) diseases are accompanied by the secretion of Volatile Organic Compounds (VOCs) in a specific composition. Detection of this VOC mixture in very low concentrations could help early detection, with possibilities for curing and prevention of spreading. To this end, the availability of a versatile, cheap, and yet very sensitive electronic nose system is needed. Such a system would consist of a generic sensor platform, based on micro- or nanotechnology in order to make it sufficiently sensitive, coated with capture layers, specific for the application. Because the capture layers cannot be made 100% specific for a given VOC, the readout of an array of sensors, each coated with a different layer, will have to be processed to yield a fingerprint of the composition of the mixture. This system is mimicking the way the (human) olfactory system works, where a pattern of responses from various odorant receptors in the nose is recognised as a specific smell. Hence, the name of an electronic nose.
Early detection of diseases is only one of the many challenges in society where cheap, yet sensitive sensor platforms for VOC detection in air would be of great benefit. Over the years, applications have been identified in prevention of food spoilage (rotting of crop), forensics (laboratories for synthetic drugs, explosives), safety (CO detection in low concentrations at home, wearable chemical sensors in plants, forest fires), to preventive maintenance (changes in VOC composition to indicate lubrication wear-out).
To this end, the applicants have taken up the challenge to try and write a proposal to be submitted in a PPS call in 2020, aimed at developing a cheap, yet very sensitive VOC detection system based on electronic nose principles. The aim is to bring together experts, both from industry and from science, in the fields of sensor devices, chemistry of functional thin layers, read-out electronics and data processing. In this HiTMaT project we plan to carry out a pilot study to check the feasibility and the current attainable accuracy with existing state-of-the-art technologies, which have never been combined to be used as VOC sensors.
In the proposed project we plan to pursue three separate goals:
First, we want to study the ultimate sensitivity of the combination of a photonic sensor platform (specifically a MicroRingResonator, or MRR), designed and manufactured by LioniX International BV, which will be functionalised with a capture layer made of polymer brushes. To this end, the chemistry of the polymer brushes needs to be modified at the University of Twente, in order to allow them to adhere to the Si3N4 top layer of the MRR device. Subsequently, a series of measurements needs to be carried out by Saxion University of Applied Sciences, in order to determine the ultimate sensitivity of the complete system towards acetone vapour at low concentrations (<10 ppm).
Secondly, we want to analyse the composition of a number of gas samples obtained via Avivet, derived from blood lice infected stables. This analysis should provide us with a rough understanding of the specific VOCs to be detected and at what levels they are present.
Finally, we want to dedicate part of the available budget and time to bringing together relevant partners within the Netherlands, both from Science and from Industry, to prepare the consortium for the PPS proposal, currently envisioned to be submitted in 2020. With many of the potential partners already a collaboration or in-depth discussion about this idea are in place, so there is a solid base to start from.

Why study nanotechnology?
Nanotechnology today plays a very important role in our lives and will undoubtfully increase its impact in the future. Whether in food, medicine, the environment, cosmetics or electronics, nanotech is the technology of the future! Consider the iPod, chemotherapy without side effects, self-cleaning glass windows and scratch resistant automotive paints. These are all nanotechnology enabled products. None of these would be there without nanotechnology. This is the reason why you want to study nanotechnology.
If you are studying a BSc course in Biology and Medical Laboratory Research, Chemistry, Electrical Engineering, Applied Physics or Mechanical Engineering at Saxion, you may decide to take on the Nanotechnology study program, as a specialization within your BSc program. From the third year of your BSc course, you will dive into the world of nanotechnology. This implies taking a number of subjects in nanotechnology, doing a Living Technology project at one of the Nanotechnology lectorates, and choosing a nanotechnology-related subject for your internship and final thesis work.
MSc Applied Nanotechnology
You can also go for the MSc Applied Nanotechnology course. This involves a 2-year MSc-level training in different subjects of applied nanotechnology research including numerous hands-on practicals (including cleanroom work) and projects related to ongoing research work in the research groups NanoBio and NanoPhysicsInterface.
More information about our Master programme can be found on the website of the Master Applied Nanotechnology.
