Polymer-assisted microcontact printing: Using a tailor-made polydimethylsiloxane (PDMS) stamp for precise patterning of rough surfaces

open access: yes, 2023
Rough, capillary-active surfaces remain demanding substrates for microcontact printing (µCP), as the diffusive mobility of the ink thereon drastically limits the printing resolution.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.
