The project is evaluating biosensors as a fast screening tool for monitoring/screening of contaminants (mycotoxins) in food and feed. Aptamers and Mips (Moleculary Imprinted Polymers) can be considered as an alternative of antibodies, with several advantages compared with the latest (animal friendly, adaptable, cheap…). Aptamers will be selected and characterized by analytical methods (SPR, QCM). These fast screening test will be developed based on lateral diffusion methodology (dipstick) and are based on newly developed nanoparticels. A further development towards more complicated Biomems biosensors is a possibility. This multi-disciplinary project involves aspects of biotechnology, molecular biology, chemistry , surface chemistry.
The project can be seen in the view of the high need of fast and payable alternatives for chemical analytical tools.
The project involves:
Full PhD grant (a one year proof period, that can be extended for the full PhD period).
A diploma as Master in Biology, Chemistry, Biomedical Sciences, Biological Engineer, Civil engineer, Pharmacist, Veterinarian sciences or any other relevant field
Information and application
Applications are open to 1st class students worldwide.
Start of the project is November 2021
Projects can be adjusted towards the personal interest of motivated candidates. Therefore we also encourage people to submit their CV for the open positions below or for a ‘personal’ topic within the expertise areas of the lab.
For further information and application, please send your CV with a letter to express your interest and three references to Johan Robbens PhD MBA by email Johan.firstname.lastname@example.org
Antwerp is the real urban deal, a refreshingly down-to-earth yet vivacious cosmopolitan habitat blessed with magnificent architecture, fashionable shop fronts, beer-washed pubs, dazzling monuments, jazzed-up clubs, inspired artworks and restaurant tables piled with plates of superb Belgian and multicultural food. Antwerp, home of the Flemish Baroque master Rubens, not only has a wealth of outstanding museums, picturesque galleries, sculpted streets and beautiful architecture, but is also laced with refreshing greenery and urban haunts. Its culture, history, vibrant nightlife and world class shopping are within easy reach, thanks to excellent access by air, train, motorway and even water.
As a fashion city Antwerp owes its reputation to the pioneers of the fashion movement, the so-called 'Antwerp Six': Walter Van Beirendonck, Ann Demeulemeester, Dries Van Noten, Dirk Van Saene, Dirk Bikkembergs and Marina Yee travelled to London and Paris together in the Eighties as well as Martin Margiela (the seventh). Together they conquered the fashion world with their very distinct vision of fashion.
Antwerp World Diamond Centre is not just a slogan. “Antwerp quality” and “Antwerp cut” are international trade terms synonymous with perfect processing and flawless beauty. Antwerp has a long and magnificent tradition as a diamond city. Since the 15th Century the city has played an important role in the diamond trade and industry.
Some 1,500 diamond companies are concentrated in the city centre. In less than one square kilometre, nearby Central Station, more than half of all cut diamonds pass through a network of diamond cutting shops, diamond bourses and selling centres. Of the 25 diamond exchanges worldwide, 4 operate in Antwerp. Elegant showrooms offer the visitor fascinating tours and the opportunity to visit interesting exhibitions
Antwerp is a pocketsize metropolis.
Antwerp is situated less than one (or two) hour away from Amsterdam, Paris, London, Brussels…

The most versatile and accurate particle sizing and counting analyzer available today. Using The Coulter Principle, also known as ESZ (Electrical Sensing Zone Method), the Multisizer 3 Coulter Counter provides number, volume, mass and surface area size distributions in one measurement, with an overall sizing range of 0.4 µm to 1,200 µm. Its response is unaffected by particle color, shape, composition or refractive index. The Coulter Principle is the absolute leading technology in high resolution and accuracy and it is further enhanced in the Multisizer 3 by using a Digital Pulse Processor (DPP). You will get the ultra-high resolution, multiple channel analysis and accuracy not provided by any other technology. It all makes the Multisizer 3 indispensable for any industrial or life science research project involving sizing and/or counting. Equally a powerful tool for quality control, it provides the analyst with a system which is easy to use, yet so technologically advanced that it is able to solve most particle sizing problems.
Particles suspended in a weak electrolyte solution are drawn through a small aperture, separating two electrodes between which an electric current flows. The voltage applied across the aperture creates a "sensing zone". As particles pass through the aperture (or "sensing zone"), they displace their own volume of electrolyte, momentarily increasing the impedance of the aperture.
This change in impedance produces a pulse that is digitally processed in real time. The Coulter Principle states that the pulse is directly proportional to the tri-dimensional volume of the particle that produced it. Analyzing these pulses enables a size distribution to be acquired and displayed in volume (µm3 or fL) and diameter (µm). In addition, a metering device is used to draw a known volume of the particle suspension through the aperture; a count of the number of pulses can then yield the concentration of particles in the sample.
The EB&T research group has an array of 6 climate rooms in which temperature and light cycle can be adjusted to the prefered test conditions and/or test organism. All rooms have recently been upgraded with new control units and cooling and heating systems. The flexible infrastructure of these climate rooms allows us to perform scientific research on a wide variety of test organisms such as fresh and marine species of algae, invertebrates (Daphnia, Artemia,...) and fish (Carp, Zebrafish, Sea bass, ...).
In traditional Flow-through Aquaculture Systems, water is passed through the culture system only once and is then discharged back to the aquatic environment. The flow of water through the culture system supplies oxygen to the fish and carries dissolved and suspended wastes out of the system. Water quality within the culture system is maintained by flushing of contaminants and by replacing all system water before dissolved oxygen concentrations drop below minimum acceptable limits or contaminate concentrations (i.e. ammonia, solids, and carbon dioxide) can accumulate to above maximum acceptable limits. Flow through systems are where fish are held in ponds, tanks, raceways or other specially designed apparatus which have water constantly passing through them. These systems can be used to grow or expose either fresh or marine species.
Intensive and semi-intensive flow through culture systems are those where fish are stocked at high densities and are fed on artificial diets. Appropriate stocking densities will depend on the species stocked and prevailing environmental conditions. These systems generally require large quantities of water to allow high stocking densities without water becoming degraded through the system.
Flow through systems may be either gravity feed or use pumps to supply their water. The advantage of gravity fed systems are that there are no pumping costs involved.
The main goal of a Flow Through system connected to a peristaltic pump, is to obtain a constant concentration of an element in your exposuretanks.
You always start from a stocksolution. Attached ( and in) this stocksolution, tubings are connected with a peristaltic pump. This pump pumps your stocksolution through tubings into your exposure tanks at a certain flow rate. In your tank you'd have to provide a continous flow through, through your system, to keep the same concentration of your stocksolution at any time during exposure. From your exposuretank, you'd have to make a connection with your drainnigsystem, to prevent water rising above the top of the tank.
The lab is equipped with a number of different spectroscopy applications for determining metal concentrations in a wide variety of samples including water, soil and organic content. Total and dissolved concentrations can be measured with Graphite Furnace Atomic Absorption Spectrometry (GFAAS), Flame Atomic Absorption Spectrometry (FAAS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). Our latest acquisition is a quadrupole Inductively Coupled Plasma Mass Spectrometer (ICP-MS) with autosampler (Varian, Palo Alto, USA) which allows the direct detection of different isotopes from the same element (e.g. for Cu: Cu-63 and Cu-65). This technique of isotope discrimination is currently being implemented as an alternative to radio-active labeled tracer studies.
