Abstract Exploring the potential of microfluidic systems, this study presents a groundbreaking approach harnessing energy in flows within purpose‐built microreactor, enabling precise deposition functional biomaterials. Upon optimizing reactor dimensions and integrating it into system, sequentially flow‐induced DNA hydrogels transformation DNA‐protein hybrid materials with SpyTag/SpyCatcher technology is investigated. However, limited functionalization rates restrict its viability for targeted biocatalytic processes. Therefore, direct phenolic acid decarboxylase investigated, which efficiently deposited but shows performance due to shear‐induced denaturation. This challenge overcome by two‐step immobilization process, resulting bioreactors demonstrating initial high space‐time yields up 7000 g L −1 d , whose process stability proves unsatisfactory. exploiting principle immobilize recombinant E. coli cells as living overexpressing biocatalytically relevant enzymes, are produced that show equally continuous whole‐cell catalysis remain constant over periods 10 days. The insights gained offer optimization strategies advanced innovative systems holding promise applications fundamental science, biosensing, scalable production microreactors biocatalysis bioremediation.
