Delta Diagnostics raises from i&i Biotech Fund and other investors €5.25 million in Series A Funding to Revolutionize Biosensing Technology

09 May 2023


Prague, May 9, 2023 – Dutch start-up, Delta Diagnostics, a leader in label-free, multiplexed biosensing, announced today that it has successfully secured Series A funding of €5.25 million. The funding round was made possible by a consortium of four investors: i&i Biotech Fund, Oost NL, InnovationQuarter and PhotonDelta.

The investment will fuel the company's ambitious vision of making rapid, sensitive, and low-cost biosensors accessible to all, transforming the Life Sciences industry and paving the way for novel and faster solutions in Life Sciences research. Delta Diagnostics is a TNO spin-off that simplifies biosensing, the detection of biomolecules, using photonic integrated circuits. This cost-effective method accelerates Life Sciences research and enables multiplexing to analyze multiple biomolecules at once. 

"Securing Series A funding marks a significant milestone for Delta Diagnostics, validating our technology and our vision to create multiplexed biosensing," says Guy Dewil, CEO of Delta Diagnostics. "We are grateful to our investors for their support and strongly believe in our mission. This investment will accelerate the launch of our first product. It will unlock the full potential of our biosensing technology to drive discoveries in Life Sciences."  

“We firmly believe that Delta´s technology can effectively bring a significant improvement in the biosensing arena. We are convinced, the interest of industrial partners for this technology maintains the committed team of Delta on the right trajectory to future success.”
