I-Tech is a Swedish company limited by shares and founded in 2000 by a group of researchers from University of Gothenburg and Chalmers University of Technology. I-Tech’s biocide Selektope® (generic name Medetomidine) has sprung from extensive research on the development of environmentally sound marine paints through a government funded multi-year research project. Several putative biocides were included in this project, but Selektope® distinguished from the others when it was discovered to affect the behaviour of the barnacle larvae so that they would not settle on prepared surfaces. The substance was particularly interesting as the effect can be identified already at nano-molar concentrations. Further development refined Selektope® to a potent, ecologically verified marine biocide for use as an antifoulant in marine bottom paints. The technology holds extensive patent protection for all relevant maritime nations. Selektope® has received regulatory approvals in Japan and Korea and is under registration in Europe and China.
