Lateral Flow Assay (LFA) have enjoyed a broad acceptance as an aid in the large field of analysis and diagnostics for years.

Their easy useability, their low price and their fast evaluability are, however, in contrast to their worse limits of detection compared to other analytical methods (ELISA, HPLC, MS) and the increasing demand for multi-parameter methods.

The q-Flow project aims to obtain a novel LFT system that contains the advantages of the LFTs, but increases the sensitivity to the level of ELISAs and allowing multiparameter analysis through the combination of semiconductor nanoparticles – so-called quantum dots – and enzymatic signal amplification.
