Although hydrogels have been of both scientific and technical interest for a very long time, research into these compounds is very far from complete. Indeed, we can witness widespread research efforts to upgrade hydrogels into ever more sophisticated materials, with synthetic and physical chemists striving to make hydrogel structures and properties ever more complex and more ingenious (De France et al., 2018; Raghuwanshi and Garnier, 2019). Modern researchers are trying to make hydrogels more and more similar to materials found in biological bodies, with the aim of enabling such hydrogels to effectively mimic their bio-counterparts and thereby become available for increasingly advanced use in medicine (Du et al., 2015; Gharazi et al., 2018; Klotz et al., 2018; Li et al., 2018; Rosenberg et al., 2019; Xie et al., 2019). However, hydrogel applications are not limited to their traditional areas – the food and pharma industries – as they find use either directly as materials with specific properties or indirectly as templates for other products [see, for example, Zhou et al. (2019)].

The articles covering this research topic represent only a small window on contemporary research and development in the field of hydrogels. They are short pieces illustrating the whole mosaic with a special focus on bio-based materials, and report, for example, on progress in the development of self-healing hydrogels or bio-inks designed for the 3D printing of hydrogels for application in tissue engineering, as well as on experience with cell differentiation in relation to hydrogel stiffness and the potential application of hydrogels in the treatment of aneurysms.
