Project description
Exploring the potential of microalgae as a soft actuator
Recent scientific research is working on ways to create engineered living materials – materials formed from living cells that can interact with their environment and imitate biological systems. The unique properties of microalgae, namely that they change behaviour and move in response to light, may prove suitable for creating a living material that deforms or moves as a whole. Funded by the European Research Council, the AlgaeLeaf project aims to develop the first microalgae-based living material that can be dynamically controlled by light. The project will explore microalgae behaviour in hydrogel and validate ways to reinforce it with polymers. The new material will open doors to novel applications ranging from soft robots to photosynthetic devices.
Objective
Nature fabricates materials with remarkable properties, having the ability to grow, move and sense their environment. Such dynamic and interactive materials are in strong contrast with man-made synthetic materials. Recent scientific interest has emerged to incorporate living cells into materials to form living materials, using most often muscle cells or bacteria. While underexplored, microalgae-based living materials are highly promising due to the light-driven movement of microalgae. The aim of this ERC project is to develop the first microalgae-based photosynthetic living material with a dynamically light-controllable shape and with locally tuned (mechanical) properties.
The fabrication of light-responsive microalgal living materials will be possible through novel fundamental knowledge that we will gain regarding the growth and motion of microalgae within a porous hydrogel. Although this constrained environment mimics one of the microalgae natural habitats (soil), we have limited understanding of the microalgae behaviour within such an environment. We will first investigate how cells move within a porous environment and how they respond to light, with the goal of using light for 3D patterning. We will then explore how the hydrogel-based living material can be locally mechanically reinforced with cell-secreted polymers, and finally how to harness the microalgae light response as a mean to create a soft actuator.
My independent research team uniquely combines expertise in microalgae cell biophysics and in engineered living materials, and we are thus ideally positioned to take on the challenge of creating microalgae-based living materials dynamically controlled by light. This ERC project opens up a new class of materials with life-like functionalities such as shape change and light-sensing, which are likely to find wide applications, from soft robots to photosynthetic devices.
