ERC PoC – Holophrase

[Edit February 2023: Holophrase is now funded by the EPSRC, due to the UK-EU ongoing negotiations.] We are happy to share the news that the group has been awarded an ERC Proof of Concept grant, to develop an integrated on-chip pH sensor. HolopHrase is based on the ERC consolidator grant AMPHIBIANS, which introduces the metasurfaces technology in microfluidic environments. With HolopHrase, we will develop a flexible solution for the real time, label free, quantitative optical imaging readout of the pH level of a liquid solution. Our approach brings together the ease of access, simplicity, and cost of bulkier solutions, with the accuracy and level of integration of the most sophisticated sensors. Our device creates a holographic image that changes in real time with the pH of the solution, without requiring the introduction of absorbing dyes or costly and complicated sensing circuitry and cumbersome calibration steps.
