“…[ 26,27,40 ] Moreover, these self‐growing hydrogels also exhibit a fracture strain (from 12% to 50%) similar to that of skin, muscle, and hydrogels made of gellan gum or chitosan (Table S6, Supporting Information). [ 27,40 ] Therefore, the mechanical properties of self‐growing hydrogels could be rationally tailored to that of biological materials.…”

[26,27,[30][31][32][33][34][35][36][37][38][39] previously reported hydrogel-based actuation systems (Figure 5d and Table S7 (Supporting Information)), such as electroresponsive poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) gel strip, [52] anisotropic swelling of 4D printed hydrogel, [50] photoresponsive graphene-elastin gel, [51] etc. [45][46][47][48][49] It is revealed that our self-growing PAAm hydrogel could generate much higher power density than those hydrogel-based actuation systems, despite its high water content (71.5 wt%).…”

“…To implement our design rationale, as depicted in Figure 1b, we choose AAm as the precursor, which is usually used to prepare hydrogel materials through free radical polymerization. [26,27] As an active material with unpaired electrons, [28] liquid metals of EGaIn have been widely exploited as a highefficiency radical initiator for monomers like acrylamides or acrylates, in order to synthesize polymer or hydrogel materials. Therefore, a polyacrylamide (PAAm)/EGaIn hydrogel composites could be readily obtained by uniformly dispersing EGaIn nanoparticles (≈100 nm in diameter) within AAm aqueous solution under ultrasonication.…”

The production of natural materials is achieved through a bottom‐up approach, in which materials spontaneously grow and adapt to the external environment. Synthetic materials are specifically designed and fabricated as engineered materials; however, they are far away from these natural self‐growing attributes. Thus, design and fabrication of synthetic material systems to replicate the self‐growing characteristics of those natural prototypes (i.e., hairs and nails) remains challenging. Inspired by the self‐growing behaviors of keratin proteins, here the fabrication of synthetic hydrogels (i.e., polyacrylamide (PAAm)) from the free radical polymerization at the interface between AAm precursor solution and liquid metals (i.e., eutectic gallium–indium (EGaIn)) is reported. The newly formed hydrogel materials at the EGaIn/AAm precursor interface gradually push the whole hydrogel upward, enabling the self‐growing of these synthetic hydrogel materials. This work not only endows the fabrication of synthetic materials with unprecedented self‐growing characters, but also broadens the potential applications of self‐growing materials in actuation and soft robotics.

With the “many-headed” slime mold Physarum polycelphalum having been voted the unicellular organism of the year 2021 by the German Society of Protozoology, we are reminded that a large part of nature's huge variety of life forms is easily overlooked – both by the general public and researchers alike. Indeed, whereas several animals such as mussels or spiders have already inspired many scientists to create novel materials with glue-like properties, there is much more to discover in the flora and fauna. Here, we provide an overview of naturally occurring slimy substances with adhesive properties and categorize them in terms of the main chemical motifs that convey their stickiness, i.e. , carbohydrate-, protein-, and glycoprotein-based biological glues. Furthermore, we highlight selected recent developments in the area of material design and functionalization that aim at making use of such biological compounds for novel applications in medicine – either by conjugating adhesive motifs found in nature to biological or synthetic macromolecules or by synthetically creating (multi-)functional materials, which combine adhesive properties with additional, problem-specific (and sometimes tunable) features.
