After a current breakthrough, it appears solely a matter of time earlier than growers have a helpful virus sensor that gives fast perception into the presence of pathogenic viruses of their water techniques. “We’re only one hurdle away from a world first,” says venture chief André van der Wurff of Normac Groen Agro Management. Along with Kees Koopal of Sendot Analysis, he provides an replace on the daring venture, whose ending line is in sight, at Glastuinbouw Waterproof.
Though a virus sensor in itself just isn’t distinctive, current units are far too massive and expensive to contemplate sensible use at horticultural places in any respect. Due to this fact, the “virus sensor growth” venture can actually be referred to as daring.

Sensor features
“Handy and reasonably priced sensors for each day use at horticultural places merely don’t exist,” says Van der Wurff. “Whereas there’s a nice want for them worldwide, as water-borne viruses are a rising downside in skilled horticulture and restrict alternatives to recirculate water. Glastuinbouw Nederland and Plantum acknowledged this and made this advanced venture doable. We’re more than happy to have cleared one other essential hurdle. The virus sensor has been realized and is functioning. That in itself is a world first. For repeated real-world use, we now want to beat yet one more hurdle: cleansing the detector.”
Lively and inactive virulent materials
The venture chief tells his story along with Kees Koopal, R&D supervisor inside sensor maker Sendot Analysis. “It took blood, sweat, and tears to translate the big, current laboratory idea right into a helpful, functioning sensible instrument that gives close to real-time readability,” Koopal says. “For the primary time, this makes use of fiber optics, during which our firm specializes.”
Virus detection takes place by loading the detector with antibodies and bringing it into contact with water during which there could also be virulent materials. These bind to the antibodies and, with free secondary antibodies current, have been handled with a fluorescent substance. This makes them ‘readable’ to the optical sensor. What’s particular is that the sensor can distinguish between energetic (strongly certain) and inactive (weakly certain) virulent materials. This distinction is important, as defined in earlier publications on Glastuinbouw Waterproof.
Another hurdle to clear
“Based mostly on this precept, the sensor can detect cucumber inexperienced mottle mosaic virus (CGMMV), PlamV, and Tulip virus-X with particular antibodies,” Van der Wurff continues. “What nonetheless must be developed is a regeneration technique. That could be a flushing technique that permits us to discharge the detector in order that it’s clear and prepared for the subsequent measurement. That requires greater than a container of water, so there’s nonetheless some work forward.”
Observe-up venture requested
As the unique venture is now full, the venture group – once more with assist from Plantum and Glastuinbouw Nederland – has utilized to the Prime Sector for a follow-up venture. Given the enthusiastic response from the organizations and due to the large potential of a helpful virus sensor for world horticulture and environment friendly water use, Koopal and Van der Wurff are longing for a inexperienced gentle.
“By the tip of this yr, we’ll know whether or not we will go forward,” the Sendot researcher concludes. “Then we may choose up the thread in spring ’24.”
