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.

Novel fluorescent amphiphilic block copolymers: photophysics behavior and interactions with DNA

eXPRESS Polymer Letters, 2007
In this study, novel amphiphilic fluorescent copolymers poly(N-vinylpyrrolidone)-b-poly(N-methacryloyl-N'-(α-naphthyl)thiourea) (PVP-b-PNT) were synthesized via ATRP with poly(N-vinylpyrrolidone)-Cl as macroinitiator and N-methacryloyl-N'-α ...

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

Non-native three-dimensional block copolymer morphologies

Nature Communications, 2016
Molecules can self-assemble to form ordered phases with defined shape and periodicity, but there are a limited set of morphologies reported. Here, the authors have manipulated block copolymer thin films via an iterative assembly process to form a diverse
