Moreover, the hydrogel demonstrates a low strain detection limit of 1 % and shows great potential for applications in human health monitoring. Interestingly, based on the principle of Morse code, the hydrogel can be used for information transmission in hazardous environments for emergency signaling. More importantly, when used as an electrolyte in flexible zinc-ion battery, it significantly inhibits zinc dendrite growth and supports stable charge-discharge cycles, making it ideal for small flexible electronic devices.

This study aimed to explore the effects of different charged polysaccharides on the release and bioaccessibility of β-carotene from 3D printed delivery systems and to analyze their relationship with protein secondary structure.

The printed systems induced by adding guar gum (neutral), locust bean gum (neutral) and gum arabic (anionic) exhibited higher DH of protein and release of FFAs (>91 %), higher β-carotene release (>93 %) and bioaccessibility (>30 %). The release of β-carotene from the printed systems during digestion conformed to the logistic model, with frame erosion and Fickian diffusion being main mechanisms.
