Shaping hydrogel bioinks into 3D, multiscale, perfusable models using multimodal printing

This paper develops a hybrid 3D printing platform combining digital light projection and two-photon ablation to create multiscale, perfusable hydrogel constructs that mimic in vivo-like structures.

3D osteocyte networks under Pulsatile Unidirectional Fluid Flow Stimuli (PUFFS)

This study develops a microfluidic model to investigate how pulsatile fluid flow affects 3D osteocyte networks, showing mechanotransduction via calcium signals and sustained gene expression.

Multipath projection stereolithography (MPS) for 3D printing microfluidic devices

The paper introduces MPS, a 3D printing method for microfluidic devices, enabling high-resolution features on centimeter-sized constructs.
