CellStudio: a Modular, Tunable and Accessible Platform for Analysis of Growth Factors Secretions in Cell Cultures.

Traditional cell culture methods face significant limitations in monitoring cell secretions with spatial and temporal precision. Advanced microsystems incorporating biosensors have been developed to address these challenges, but they tend to lack versatility, and their complexity, along with the requirement for specialized equipment, limits their broader adoption. CellStudio offers an innovative, user-friendly solution that exploits Printing and Vacuum Lithography combined with bead-based assays to create modular and tunable cell patterns surrounded by biosensors.

Engineering Metal-Phenolic Network Nanoparticles via Microfluidics.

Microfluidics opens new avenues for materials engineering, as it enables scalable synthesis and provides highly controllable environments for reactions. Herein, we leverage microfluidics to engineer the properties of (bioactive) metal-phenolic network nanoparticles (MPN NPs), an emerging and highly modular nanoparticle platform for the incorporation and delivery of bioactive cargo. By varying the microfluidics operating parameters (flow rate ratio, total flow rate, temperature) and NP composition, we assemble MPN NPs, which consist of poly(ethylene glycol), biomacromolecules, metal ions, and polyphenols.
