Photonic hydrogel sensors [PDF]

open access: yesBiotechnology 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]

open access: yesNature 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

open access: yesSupramolecular 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 ...

Programmable hydrogels [PDF]

open access: yesBiomaterials, 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.
