“…During the UV light-induced polymerization process, in situ formation of carboxyl-Zr 4+ coordination crosslinking and LMA hydrophobic association crosslinking occurred, endowing the hydrogel materials with a cohesive and integral network structure. [23][24][25] Throughout the incubation period in water, this cross-linked network was further strengthened on account of the generation of electrostatic interactions and the structural reconfiguration of the coordination complexes. More specifically, during the incubation of the pre-hydrogels in water, the electrostatic interactions between the N + of CTAB and the COO À on PAA chains gradually emerged, which was attributed to the partial ionization of AAc units accompanying the increase in pH.…”

“…As illustrated in Figure 3j, the fracture strength and Young's modulus of various DLP 3D printing hydrogels are summarized on an Ashby plot for comparison with the resilience hydrogels with tissue‐like softness. Remarkably, the fracture strength and Young's modulus of the springiness hydrogels in this work are much higher than those of various DLP 3D printed hydrogels such as P(DMAEMA‐MAA) hydrogel, [ 21 ] AAm‐PEGDA hydrogel, [ 22 ] GMHA‐PSPA hydrogel, [ 23 ] PSMA double‐network (DN) hydrogel, [ 24 ] MA‐Starch hydrogel, [ 25 ] PEG‐DA hydrogel, [ 26 ] GelMA hydrogel, [ 27 ] Sil‐MA hydrogel, [ 28 ] and HG hydrogel. [ 29 ] It can be seen that the stiffness of the resilience hydrogels is mechanically tunable in a wide range from a few kilopascals to hundreds of kilopascals, thus providing promising candidates for the fabrication of structurally sophisticated multiple soft tissue mimics.…”

Biomimicking organ phantoms with vivid biological structures and soft and slippery features are essential for in vitro biomedical applications yet remain hither to unmet challenges in their fabrication such as balancing between spatial structural complexity and matchable mechanical properties. Herein, 3D printable tissue-mimicking elastomeric double network hydrogels with tailorable stiffness are evolved to idiosyncratically match diverse biological soft tissues by regulating the compositions of hydrogel matrix and the density of metal coordination bonds. Relying on digital light processing 3D printing, various mechanically tunable biomimetic volumetric hydrogel organ constructs with structural complexity and fidelity, including kidney, brain, heart, liver, stomach, lung, trachea, intestine, and even the intricate vascularized tissues, are fabricated faultlessly. Proof-of-concept 3D printed hydrogel heart and liver phantoms provide sophisticated internal channels and cavity structures and external realistic anatomical architectures that more closely mimic native organs. For the in vitro application demonstration, a 3D printed hydrogel brain phantom with tortuous cerebral arteries and slippery characters serves as an effective neurosurgical training platform for realistic simulation of endovascular interventions. This platform offers a means to construct mechanically precisely tunable hydrogel-based biomimetic organ phantoms that are expected to be used in surgical training, medical device testing, and organs-on-chips.

“…Finally, Figure 6h offers insight into the stress-strain curves of the self-healed hydrogels, showcasing their performance over increasing healing durations. Zhang et al [90] experimented with Antheraea pernyi silk fibroin bioinks for DLP 3D printing, offering new opportunities in bioprinting and regenerative medicine. In another innovative stride, Xiang et al [91] focused on creating 3D-printed high-toughness double network hydrogels via DLP, contributing to the development of mechanically robust hydrogel materials.…”
