The fabrication of tissue-like soft batteries thus remains a challenge. Here, the first ultrasoft batteries totally based on hydrogels are reported. The ultrasoft batteries exhibit Young's moduli of 80kPa, perfectly matching skin and organs (e.g., heart). The high specific capacities of 82 mAh...
With a mechanistic understanding of the devices, we further characterize the performance of these mechanoionic hydrogel generators in the context of practical applications. The optimized electrode layout (ACC as the working electrode and CC as the counter electrode) was used for all the tests thereaft...
All materials were purchased from Sigma-Aldrich (Merck KGaA). For all droplet power sources, low-gelling-temperature (LGT) agarose was used to build the hydrogel scaffold. This material has enough gel strength for fabrication at around room temperature. Other materials were dissolved in Milli-Q w...
Both in vitro and in vivo studies have shown that the “sandwich” pretargeting platform was able to diagnose inflammation by targeting activated macrophages as well as improve the therapeutic efficacy by amplifying the drug delivery to the inflamed tissue. The overall results support that our new ...
2.2. Crosslinked IonDuring the fabrication process, some natural polymer like agar and gelatin, could form gels by physical heating-cooling method. Besides, other natural polymer needs to be crosslinked by ion (Fe3+, Ca2+, Li+) for forming hydrogel, such as alginate, κ-carrageenan, hyaluronic...
Wipe the case dry with a clean lint free tissue, then leave the case upside down on a clean tissue to air dry and place the lids face down. It is important to completely dry the case to prevent bacterial growth. Reassemble and store ...
Over the years, immense progress has been made in the field of bone tissue engineering. Various deposition techniques have successfully fabricated multifunctional biocompatible, non-corrosive, and mechanically resistant bioactive coatings for metallic implants with the aim of mimicking the structural and fun...
A hydrogel-mineral composite scaffold for osteochondral interface tissue engineering. Tissue Eng. 2012, 18, 533–545. [Google Scholar] [CrossRef] [PubMed] Jiang, J.; Tang, A.; Ateshian, G.A.; Guo, X.E.; Hung, C.T.; Lu, H.H. Bioactive stratified polymer ceramic-hydrogel scaffold ...
Droplets containing high densities of different cell types were printed onto a fibrin hydrogel and embedded into a sandwich-like structure to encapsulate the printed aggregates in a 3D environment. With the developed method it is possible to print different cell types in various constellations, ...
The hydraulic cushioning effect created by intercellular fluid communication may help to impart realistic shape and tissue-like consistency to the implant. The viscosity of the filler at body temperature is preferably related to the passage size to inhibit excessive free flow between cells in the ...
