and while unoptimized, have potential as conductive biological interfaces. To explore the versatility of the TR-CP, we studied its processability by deposition on warm substrates or injection in warm fluids. First, we drop-casted 5.6 wt% TR-CP onto a glass slide heated to 37 °C (Fig. , Supplementary Video 2). The gel formed instantly on contact with the glass and assumed a hemispherical shape. The TR-CP gel was sliced with a razor blade, and the two halves maintained their shape well when kept at 37 °C. The gel was then allowed to cool to room temperature and was re-formed on heating the glass slide to 37 °C, thus displaying a selfhealing behavior. Further, we investigated the injectability of TR-CPs into a warm, viscous alginate precursor solution (non-crosslinked) maintained at 37 °C (Fig. Video 3). The injected TR-CP gelled instantly, displayed minimal spreading, and stayed gelled as long as the temperature was maintained above 35 °C (SI Section 3.12.2, Fig. ).
