Biphasic Granular Bioinks for Biofabrication of High Cell Density Constructs for Dermal Regeneration

Advanced Healthcare Materials, EarlyView.
This study introduces a biphasic granular bioink (µInk) that enables 3D bioprinting of high cell density constructs for dermal regeneration. The bioink promotes cell proliferation, ECM deposition, and neovascularization, leading to tissue integration and reduced scar formation in vivo.

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

Advanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.
