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.

Functionalized Hydrogel-Based Wearable Gas and Humidity Sensors

open access: yesNano-Micro Letters, 2023
Breathing is an inherent human activity; however, the composition of the air we inhale and gas exhale remains unknown to us. To address this, wearable vapor sensors can help people monitor air composition in real time to avoid underlying risks, and for ...

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 ...
