“…There were a lot of cells adhering to the TCPS, but no obvious cell adhesion was observed from the hydrogel (Figure a,b), the number of cells in the experimental group and the control group was counted (Figure c). These results suggest the antibacterial adhesion of the hydrogel, which is consistent with its excellent antiprotein adsorption, cell adhesion, and bacterial adhesion of zwitterionic betaine, this is important for preventing the formation of wound adhesions or thrombus . H-G 60 showed remarkable resistance to bacterial adhesion and prevented the formation of biofilms.…”

Flexible electronic devices with biological therapeutic and sensing properties are one of the current research directions. Here, a multifunctional hydrogel for stress sensing and wound healing was prepared by a simple one-pot method and a solution replacement method. Among them, zwitterionic polymers promote wound healing by promoting the polarization of M2 macrophages, collagen deposition, and blood vessel formation. Glycerin can significantly improve the resilience and frost resistance of the hydrogel, ensuring that a sensor made using the hydrogel can work normally in a cold environment. In addition, zwitterionic polymers are highly biocompatible, providing excellent antibacterial adhesion to aid the wound healing process, and good electrical conductivity enhances sensing sensitivity and stability. Based on these properties, multifunctional hydrogels could detect human vital activities while promoting wound healing, providing new ideas for the fields of diagnosis and wound dressing.

“…According to these criteria, a number of anti-biofouling polymers have been developed that effectively prevent the adhesion of proteins, cells, and bacteria. These include hydrophilic polymers ( Epstein et al, 2012 ; Keefe et al, 2012 ; Chen et al, 2015a ; Mohan et al, 2015 ; Zhu et al, 2015 ; Guo et al, 2019 ; Jiang et al, 2020 ), e.g., PEG, PEGylated polymers, PHEMA, polysaccharides, and zwitterionic polymers ( Carr et al, 2011 ; Chen et al, 2012 ; Sin et al, 2014 ; He et al, 2016 ; Kang et al, 2016 ; Wang et al, 2018 ; He et al, 2019 ; Liu et al, 2020c ; Erathodiyil et al, 2020 ; Su et al, 2020 ; Zhang et al, 2020 ; Zhang et al, 2021a ; Zhang et al, 2021b ; Zhou et al, 2021 ), e.g., PSBMA, PCBMA, and PCBAA. Although these polymers differ in their structures and chemistry, they are all able to bind strongly to water, resulting in the presence of a layer of water that reduces interaction and attachment between the surface and the foulant.…”

The use of anti-biofouling polymers has widespread potential for counteracting marine, medical, and industrial biofouling. The anti-biofouling action is usually related to the degree of surface wettability. This review is focusing on anti-biofouling polymers with special surface wettability, and it will provide a new perspective to promote the development of anti-biofouling polymers for biomedical applications. Firstly, current anti-biofouling strategies are discussed followed by a comprehensive review of anti-biofouling polymers with specific types of surface wettability, including superhydrophilicity, hydrophilicity, and hydrophobicity. We then summarize the applications of anti-biofouling polymers with specific surface wettability in typical biomedical fields both in vivo and in vitro, such as cardiology, ophthalmology, and nephrology. Finally, the challenges and directions of the development of anti-biofouling polymers with special surface wettability are discussed. It is helpful for future researchers to choose suitable anti-biofouling polymers with special surface wettability for specific biomedical applications.

“…Particularly, the hydrogels are attracting more and more attention due to their high water content, excellent self‐healing ability, remarkable mechanical properties (high strength, high ductility, high elasticity), and so on. [ 21‐22 ] Moreover, the stratum corneum (the outermost layer of our skin) provides mechanical, physical, and chemical protection simultaneously. Many researches have been done to construct a protect film onto the hydrogel.…”

A Superhydrophobic Hydrogel for Self‐Healing and Robust Strain Sensor with Liquid Impalement Resistance

et al. 2021

Main observation and conclusion The superhydrophobic strain sensor is a fantastic direction, which could protect the strain sensor in harsh environment. Nevertheless, the self‐healing superhydrophobic strain sensor has not been reported. In this research, we developed a superhydrophobic strain sensor, which demonstrated excellent self‐healing, mechanical robustness, and liquid impalement resistance simultaneously. The key innovation is to partially embed hydrophobic graphene and carbon nanotubes into the hydrogel matrix. The hodrogel substrate endows the sample with self‐healing property. The graphene, carbon nanotubes and hydrogel together lead to an accurate and real‐time monitoring of human motion. Furthermore, the prepared sample demonstrated super‐robust superhydrophobicity, which retained superhydrophobicity after many kinds of damage (such as 1000% stretch, 10000 stretching‐releasing cycles, hand‐rub, tape‐peeling, and high‐speed drop/jet impact).
