VTT is the first in the world to have developed a drug test printed on paper. VTT used antibodies – produced by methods of molecular biology – as morphine sensing molecules when creating this printing technology-based morphine test. Using printing technology to manufacture rapid tests enables high production volumes and low production costs.   A paper-based test enables a rapid analysis of whether a compound – in this case, morphine – is present in a given sample. Possible future applications ...
