Aránzazu del Campo und Shrikrishnan Sankaran: Review Article on „Engineered Living Materials“ in Nature Reviews Materials

Research on living materials and, in particular, on targeted designed living materials is developing rapidly and in a wide variety of application areas.

In collaboration with the Centre for Cellular Microenvironment (CeMi) at the University of Glasgow, Aránzazu del Campo, scientific director of INM and head of the program division Dynamic Biomaterials, and Shrikrishnan Sankaran, head of the Bioprogrammable Materials’ program division, have summarized the development and state of the art in a review article and ventured a look into the future.

Biomaterials have evolved from inert materials that lack interaction with the body to biologically active, instructive materials that host and provide signals to surrounding cells and tissues. Engineered living materials contain living cells (responsive function) and polymeric matrices (scaffolding function) and, thus, can be designed as active and response biomaterials. In this Review, we discuss engineered living materials that incorporate microorganisms as the living, bioactive component. Microorganisms can provide complex responses to environmental stimuli, and they can be genetically engineered to allow user control over responses and integration of numerous inputs. The engineered microorganisms can either generate their own matrix, such as in biofilms, or they can be incorporated in matrices using various technologies, such as coating, 3D printing, spinning and microencapsulation. We highlight biomedical applications of such engineered living materials, including biosensing, wound healing, stem-cell-based tissue engineering and drug delivery, and provide an outlook to the challenges and future applications of engineered living materials.
