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.

Опубликована: Июль 21, 2023

Semiconductor-based biointerfaces are typically established either on the surface of plasma membrane or within cytoplasm. In Gram-negative bacteria, periplasmic space, characterized by its confinement and presence numerous enzymes peptidoglycans, offers additional opportunities for biomineralization, allowing nongenetic modulation interfaces. We demonstrate semiconductor nanocluster precipitation containing single- multiple-metal elements periplasm, as observed through various electron- x-ray-based imaging techniques. The semiconductors metastable display defect-dominant fluorescent properties. Unexpectedly, defect-rich (i.e., low-grade) nanoclusters produced in situ can still increase adenosine triphosphate levels malate production when coupled with photosensitization. expand sustainability biohybrid system to include reducing heavy metals at primary level, building living bioreactors secondary creating semi-artificial photosynthesis tertiary level. biomineralization-enabled biohybrids have potential serve defect-tolerant platforms diverse sustainable applications.
