Upcon technology brings new opportunities in the life science field


Is your assay lacking sensitivity? Do you need a lower detection limit for your lateral flow based assay?

Let us introduce a new label technology based on upconverting nanoparticles (UCNPs).

The market demand for more sensitive point-of-care assays seems to be strong nowadays. Upcon®, a concept by Kaivogen Oy and Labrox Oy, was then developed further to answer this demand. Now we offer a portable lateral flow reader, a smaller version of its original benchmark reader with similar performance.

With Upcon®, the emission is detected without autofluorescence. This leads to greater sensitivity in your assays, while you don’t need any complicated instrumentation either.

In the case of photon upconversion, detection occurs only at visible wavelengths, whereas in the case of conventional fluorescence, autofluorescence obstructs the detection of the emission at visible wavelengths. When the signals of interest are very indistinct, autofluorescence interferes with the detection since it causes other structures to become visible.
