A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Modeling of Micro-Hardness in the Au-Doped YBCO Bulk Superconductors

Journal of Superconductivity and Novel Magnetism, 2019
In this study, in order to investigate the effect of Au doping on mechanical properties of YBCO, Au-doped (from x = 1 wt% to x = 20 wt%) and pure YBa2Cu3O7-x samples were prepared by standard solid-state reaction method. The indentation load versus diagonal length of the samples under various indentation loads in the range of 0.245–2.940 N is measured.

Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

Advanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...

Plasma Gelation as an Overlooked Determinant of Transfection Efficiency in Protein Corona‐Coated Lipid Nanoparticles: Implications for In Vitro–In Vivo Translation

Advanced Healthcare Materials, EarlyView.
Upon contact with plasma, lipid nanoparticles (LNPs) rapidly acquire a protein corona (PC) that redefines their biological identity. In calcium‐containing environments, these coronated particles trigger the formation of a gel‐like plasma network, profoundly altering their transport properties and reducing their effective availability.
