Multicompartment Hydrogels [PDF]
Macromolecular Rapid Communications, 2022 AbstractHydrogels belong to the most promising materials in polymer and materials science at the moment. As they feature soft and tissue‐like character as well as high water‐content, a broad range of applications are addressed with hydrogels, e.g., tissue engineering and wound dressings but also soft robotics, drug delivery, actuators, and catalysis ...

Proceedings of the National Academy of Sciences, 2007 Fungi are increasingly identified as major pathogens in bloodstream infections, often involving indwelling devices. Materials with antifungal properties may provide an important deterrent to these infections. Here we describe amphogel, a dextran-based hydrogel into which amphotericin B is adsorbed.

Advanced Science, 2018 AbstractAntibacterial materials are recognized as important biomaterials due to their effective inhibition of bacterial infections. Hydrogels are 3D polymer networks crosslinked by either physical interactions or covalent bonds. Currently, hydrogels with an antibacterial function are a main focus in biomedical research.

Photonic hydrogel sensors [PDF]
Biotechnology Advances, 2016 Analyte-sensitive hydrogels that incorporate optical structures have emerged as sensing platforms for point-of-care diagnostics. The optical properties of the hydrogel sensors can be rationally designed and fabricated through self-assembly, microfabrication or laser writing.

Hypoxia-inducible hydrogels [PDF]
Nature Communications, 2014 Oxygen is vital for the existence of all multicellular organisms, acting as a signalling molecule regulating cellular activities. Specifically, hypoxia, which occurs when the partial pressure of oxygen falls below 5%, plays a pivotal role during development, regeneration and cancer.

Stimuli-responsive hydrogel sponge for ultrafast responsive actuator
Supramolecular Materials, 2022 With the ability to deform in response to specific stimuli, polymeric hydrogel actuators are important bionic materials. However, because shape deformation is derived from the diffusion of water molecules, the response rate of hydrogel actuators is ...

Biomaterials, 2018 Programmable hydrogels are defined as hydrogels that are able to change their properties and functions periodically, reversibly and/or sequentially on demand. They are different from those responsive hydrogels whose changes are passive or cannot be stopped or reversed once started and vice versa.

Fabrication of salt–hydrogel marbles and hollow-shell microcapsules by an aerosol gelation technique [PDF]
, 2014 We designed a new method for preparation of liquid marbles by using hydrophilic particles. Salt–hydrogel marbles were prepared by atomising droplets of hydrogel solution in a cold air column followed by rolling of the collected hydrogel microbeads in a ...
