Micromotor‐Based Biomimetic Carbon Dioxide Sequestration: Towards Mobile Microscrubbers

We describe a mobile CO₂ scrubbing platform that offers a greatly accelerated biomimetic sequestration based on a self‐propelled carbonic anhydrase (CA) functionalized micromotor. The CO₂ hydration capability of CA is coupled with the rapid movement of catalytic micromotors, and along with the corresponding fluid dynamics, results in a highly efficient mobile CO₂ scrubbing microsystem. The continuous movement of CA and enhanced mass transport of the CO₂ substrate lead to significant improvements in the sequestration efficiency and speed over stationary immobilized or free CA platforms. This system is a promising approach to rapid and enhanced CO₂ sequestration platforms for addressing growing concerns over the buildup of greenhouse gas.
