Aresa Biodetection scientists develop plant which can detect landmines and unexploded ordnance in the soil

Danish scientists of Aresa Biodetection have made a new discovery with considerable humanitarian and environmental potential. After several years of intensive research it is now possible to produce a plant, which, in the presence of specific compounds in the soil, can change colour from green to red within 3-5 weeks of growth. Hence, Aresa has developed a unique biodetection system, which has a great potential for a variety of applications. This technology is being developed to detect explosives present in landmines and unexploded
ordnance (UXO) in soil, as well as to detect and remove heavy metals in polluted soil.

The invention may significantly speed the removal of landmines and UXO in cultivatable areas to permit the subsequent use of cleared areas for agriculture to maximize socio-economic benefits. The plants will be tested and gradually introduced in landmine and UXO removal operations as the technology matures.

“This is a promising development in the efforts to find a safe and cost effective solution to detect mines, and is likely to be a very welcomed addition to current methods if successfully passing further testing in areas of operation”, says Geir Bjørsvik, Senior Advisor Landmines, Norwegian People Aid.

The technology is based on genetic engineering of the plant Thale Cress (Arabidopsis thaliana). This plant has several advantages in developing this system. For example, it is naturally selfpollinating and the plants developed by Aresa are conditionally fertile such that they are malesterile whereby growth of these Biodetection plants can be strictly controlled.

“This is a pioneering example of how we will see genetically engineered plants applied for humanitarian and environmental purposes in the future”, says professor John Mundy, Department of Plant Physiology, University of Copenhagen.

“Our team has set out to develop a technology with large potential benefits all around the world. In time we may contribute to clear land in large scale project much faster than possible today, and reduce the number of people getting injured or killed by landmines”, says CEO of Aresa, PhD Simon Østergaard.

Aresa Biodetection ApS is a biotech company founded in June 2001. Aresa is owned by Bracifeae A/S, a biotech holding and development company, and DTU Innovation A/S, A venture capital company.


Danske forskere hos Aresa Biodetection ApS har lavet en opfindelse med betydeligt humanitært og miljømæssigt potentiale. Efter adskillige års intensiv forskning er det nu muligt at producere en plante, som ved forekomst af specifikke stoffer i jord skifter farve fra grøn til rød efter 3-5 ugers vækst. Aresa´s unikke bio-detektionssystem har således stort potentiale i en række sammenhænge og anvendelsesområder. Teknologien bliver udviklet til at spore sprængstoffer, som forekommer i landminer og UXO´er (ueksploderet ammunition) i jorden, såvel som sporing og optagelse af tungmetaller i forurenet jord.

Opfindelsen forventes at kunne øge hastigheden, med hvilken landminer og UXO´er fjernes i områder egnet til landbrug m.m., hvilket vil maksimere nytten og socio-økonomiske fordele af sådanne arealer. Planterne vil blive testet og gradvist taget i anvendelse i operationer for fjernelse af landminer og UXO´er i takt med, at teknologien modnes.

”Det er en lovende opfindelse i bestræbelserne på at finde en sikker og omkostningseffektiv metode til at finde landminer, og vil sandsynligvis være et meget velkomment supplement til eksisterende metoder, såfremt den succesrigt klarer videre tests i operationelle områder” siger Geir Bjørsvik, Senior Landmine Rådgiver, Norsk Folkehjælp.

Teknologien er baseret på en genetisk modificeret plante af arten ”Gåsemad” (Arabidopsis thaliana). Planten har flere fordele i forbindelse med udvikling af systemet. Som eksempel er den selvbestøvende, og gjort betinget han-steril, hvorved spiring, vækst og spredning af planterne kan kontrolleres stringent.

”Dette er et banebrydende eksempel på, hvordan vi vil se gen-modificerede planter anvendt til humanitære og miljømæssige formål i fremtiden”, siger Professor John Mundy, Plantefysiologisk afdeling, Københavns Universitet.

”Vores team fokuserer hårdt på at udvikle en teknologi, som har store potentielle forbedringsmuligheder for hele verden. Med tiden vil vi forhåbentlig bidrage til at rydde store arealer væsentlig hurtigere end hvad er muligt i dag, og dermed reducere antallet af mennesker der såres eller dræbes af landminer”, siger administrerende direktør Ph.d. Simon Østergaard fra Aresa.

Aresa Biodetection ApS er et biotek selskab, der blev etableret i juni 2001. Aresa ejes af Bracifeae A/S et biotek holding- og udviklingsselskab, samt af DTU Innovation A/S et udviklings- og finansieringsselskab.
