3D Bioprinting of Self-Standing Silk-Based Bioink
by Zhaozhu Zheng, Jianbing Wu, Meng Liu, Heng Wang, Chunmei Li, María J. Rodriguez, Gang Li, Xiaoqin Wang and David L. Kaplan
Xiaoquin Wang at Soochow University and David Kaplan at Tufts University report on the preparation of a new silk based bioink for 3D printing of tissue constructs. The ink is composed of silk fibroin protein and PEG, which can be printed with high resolution and shape fidelity. Bone marrow mesenchymal stem cells can printed together with the ink and are growing in vitro and in vivo implanted in mice for more than 6 weeks.
Moldable Hyaluronan Hydrogel Enabled by Dynamic Metal–Bisphosphonate Coordination Chemistry for Wound Healing
by Liyang Shi, Yannan Zhao, Qifan Xie, Caixia Fan, Jöns Hilborn, Jianwu Dai and Dmitri. A. Ossipov
Biomaterial-based regenerative approaches would allow cost-effective off-the-shelf solution for the treatment of wounds. Dmitri. A. Ossipov et al. from Uppsala University in Sweden report a facile chemical strategy to generate “ready-to-use” HA supramolecular hydrogel that is uniquely adapted for the clinical applicability of wound treatment as it can fill irregularly shaped wound defects without the need for premolding. To achieve reversible crosslinking of HA chains, the biopolymer is modified with pendant bisphosphonate (BP) ligands using carbodiimide coupling and chemoselective “click” reactions. In addition, the in vivo evaluation using a rat full-thickness skin wound model shows significantly lower wound remaining rate and a thicker layer of regenerated epidermis as compared with the group left without treatment.
Skin Conformal Polymer Electrodes for Clinical ECG and EEG Recordings
by Flurin Stauffer, Moritz Thielen, Christina Sauter, Séverine Chardonnens, Simon Bachmann, Klas Tybrandt, Christian Peters, Christofer Hierold, and Janos Vörös
Janos Vörös and his collaborators from ETH Zürich, Switzerland report on wearable, preparation-free, skin-compliant, super-soft, and self-adhesive biopotential electrodes with a recording quality similar to standard commercial clinical wet gel electrodes, and better than existing dry electrodes. They can be used easily on dry as well as hairy skin without any attachment pressure and skin preparation or irritation, and result in high-fidelity recording of ECG and EEG signals, even under wet conditions. Such smart wearable electronics are of great potential interest for many specialists in the field, future healthcare applications, and the Internet of Humans.
