摘要

木材和骨骼等生物物质表现出非凡的 "生命 "特征,如自我生长能力、遇到损伤时的自我修复能力以及感知和适应环境变化的能力。这些特性是它们在复杂环境中生存和适应的关键。在材料科学领域,人们对开发能够自我监测、适应环境条件并在必要时进行自我修复的仿生材料越来越感兴趣。这些功能将延长材料的使用寿命,并为智能应用铺平道路。然而,创造具有与生物系统同等的自主性和智能性的材料仍然是一项艰巨的挑战。在这种情况下,合成生物学提供了一条大有可为的途径。它不仅可以利用活生物体固有的动态特性,还可以赋予合成材料系统无法实现的其他高级功能。这种方法可以将活细胞融入材料,使其具有自然赋予或人工设计的特性。这些创新材料被称为 "工程活体材料"(ELMs),是一类新兴的智能材料,具有自主功能,应用范围从生物医学到可持续技术不等。

Programmable Bacterial Biofilms as Engineered Living Materials

Programmable Bacterial Biofilms as Engineered Living Materials
Biological substances like wood and bone demonstrate extraordinary characteristics of “living” features, such as the ability to self-grow, self-heal upon encountering damage, and sense and adapt to environmental changes. These attributes are crucial for their survival and adaptation in complex environments. In the field of material science, there is a growing interest in developing biomimetic materials that can self-monitor, adapt to environmental conditions, and self-repair when necessary. Such capabilities would extend the lifespan of materials and pave the way for intelligent applications. However, creating materials with autonomy and intelligence on par with biological systems remains a daunting challenge. In this context, synthetic biology offers a promising avenue. It not only allows for harnessing the inherent dynamic properties of living organisms but provides the possibility of imparting additional advanced functionalities beyond the reach of synthetic materials systems. This approach enables the integration of living cells into materials, providing them with naturally endowed or artificially designed traits. These innovative materials, known as Engineered Living Materials (ELMs), represent an emerging category of smart materials capable of autonomous functions, with applications varying from biomedicine to sustainable technology.
