are shown in Fig.2a, b. We performed initial testing with the hydrogel film format (Figs.1b,2a). The cationic PIM(C4)-Mal, which has a butyl (C4) linker between the imidazolium rings, was pre-synthesized (Supplementary Fig.1). The1H NMR characterization of PIM(C4)-Mal is presented i...
In this work, we construct a layered cement skeleton with unidirectional pores by ice-template method, in which in-situ hydration was used instead of freeze-drying to effectively simplify the procedure. The ordered microstructures can be retained without freeze-drying treatments since hydration reaction...
is simple mixing of complete metal nanomaterials, such as nanoparticles, nanowires, and nanosheets, generated using different physical and chemical methods, such as electrochemical changes, chemical reduction, and photochemical reduction [51]. Typically, metal nanomaterials are mixed with a hydrogel precurs...
1 a-b). Interestingly, the recovery rates of both the modulus and the swelling ratio were found to depend on the hydrogel composition and initial properties. While the storage modulus of the stiffest 6% AAm composition increased by 2.5 times from 850 to 2′100 Pa and its swelling ratio ...
Although these newly formed tissues were not comparable to peripheral normal cartilage in terms of composition and function, the potentials of the Fe2O3/GelMA hybrid hydrogel to recruit different types of cells and potentially provide favorable iron also indicates that it is a promising scaffold ...
2i). Moreover, as described in previous studies, cell attachment to the hydrogel was dependent on the chemical composition, surface topography, and degree of porosity [12, 15]. Thus, our IPN GC hydrogels prepared with chitosan and GelMA are rich in Arg-Gly-Asp (RGD), contain a nanofiber...
(mIPN) after light irradiation. The formed network transverses both the hydrogel patch and the tissue, joining them together. In contrast to our recent earlier work15, where mIPN composition was tailored to maximize chemical interactions with the tissue, the herein explored mIPN system showcases...
2. The pharmaceutical composition of claim 1, further comprises a wetting agent. 3. The pharmaceutical composition of claim 2, wherein the wetting agent is a surfactant. 4. The pharmaceutical composition of claim 1, wherein the hydrophobic drug is about 1% to 95% by weight of the pharmac...
−1.11% °C−1at the temperature from 0 to 30 °C and 30 to 80 °C, which surpasses the performance of most polymer composites based temperature sensors. The comparison of composition and properties is summarized in TableS1. Furthermore, similarly data are fitted according to the ...
In the method of the present invention, the hydrolysis of the ester side chains is catalyzed by the gradual addition or in situ generation of a composition that will thermally or aqueously degrade to release acid or base in a mild fashion in the interior and on the surface of the hydrogel...
