Recent advances in synthetic biology and materials science have given rise to a new form of materials, namely engineered living (ELMs), which are composed matter or cell communities embedded self-regenerating matrices their own artificial scaffolds. Like natural such as bone, wood, skin, ELMs, possess the functional capabilities organisms, can grow, self-organize, self-repair when needed. They also spontaneously perform programmed biological functions upon sensing external cues. Currently, ELMs show promise for green energy production, bioremediation, disease treatment, fabricating advanced smart materials. This review first introduces dynamic features systems potential developing novel We then summarize recent research progress on emerging design strategies from both perspectives. Finally, we discuss positive impacts promoting sustainability key future directions.

Abstract Whole‐cell inorganic‐biohybrid systems, integrating inorganic photosensitizers with intact living cells, have shown great potential for solar hydrogen production. However, the typical whole cell biohybrid system often suffers from sluggish kinetics of electron transfer in transmembrane diffusion process, which severely restrict their photocatalytic activity. Here, a unique periplasmic photosensitized is constructed by translocating CuInS 2 /ZnS quantum dots (QDs) into Shewanella oneidensis MR‐1 (SW) cells that express hydrogenases. The photoexcitation and processes QDs occur simultaneously periplasm SW reduces distance transport avoids extra energy loss involved process. As expected, H generation fabricated 8.6 times higher than bare under visible light irradiation. Moreover, good viability stability this endow it an excellent sustained production within 45 h, representing most stable among reported whole‐cell systems.
