Fast and sensitive detection of biomarkers

As highlighted by the ongoing Covid-19 pandemic, the ability to quickly, cheaply and reliably detect biomarkers, such as RNA or antibodies, is an essential part of crisis preparedness.

We have developed a bio-sensor platform based on nanostructured surfaces to enable optical detection of biomarkers with 20 times higher sensitivity compared to traditional surfaces. The higher sensitivity may reduce the need of chemical amplification and enrichment steps, e.g. the PCR step for COVID-19 testing, and thus potentially give an instant result. Our cheap and scalable production technology, and the possibility to apply it to many different biomarkers, will enable widespread use of the nanoplatforms.
