Detection of Bioanalytes Using a Novel 3D Printed Sensor Technique

Recent COVID19 pandemic highlights the importance of the availability of fast/reliable biomarker detection schemes. Along with identification of a specific biomarker, there is a demand for the detection of several biomarkers simultaneously to provide additional information and improve diagnostics. Sensing devices available for simultaneous detection of several biomarkers are expensive and bulky, i.e. bench-top bio-analyzers, and limited to only a few analytes at most.

The proposed research addresses this issue with a novel bio-analyte sensor design scheme based for the first time on a configurable platform with simultaneous label-free detection of multiple biomarkers using minimal sample volumes. The platform is based on optical principles and additive manufacturing technology that had become feasible due to advanced developments in integrated photonics and additive manufacturing in recent years.

“The project is timely and highly topical. It is great to combine our efforts in realizing the main objectives of this project and the support provided by ECAS is much appreciated.

Lourdes Alwis

“The opportunity presented by ECAS re-enables a good research collaboration possibility and will allow us to work together on state-of-the-art technology within the biomedical sensing field.
