AVAC  Technology

Optical Reader & Particle Counter

The plasmonic nanoparticles are optically detected by measuring the weak scattering signal with proprietary dark-field micro-spectrophotometry. (Patents US10281330B2, EP19382244, EP19382245)


Single Particle Digital Counting

As each plasmonic nanoparticle binds specifically to a biomarker of interest, by classifying and counting the different nanoparticles it is possible to quantify the amount of each biomarker immobilized on the substrate. (pending EP19382245, EP19382244)


High sensitivity in the femtogram range has been demonstrated for different biomarkers


PSA, biomarker for prostate cancer recurrence detection.

Cardiac diseases
