Excessive CO2 and food shortage are two grand challenges of human society. Directly
converting CO2 into food materials can simultaneously alleviate both, like what green crops
do in nature. Nevertheless, natural photosynthesis has a limited energy efficiency due to low
activity and specificity of key enzyme D‐ribulose‐1, 5‐bisphosphate carboxylase/oxygenase
(RuBisCO). To enhance the efficiency, many prior studies focused on engineering the
enzymes, but this study chooses to learn from the nature to design more efficient reactors …

Inspired by the Chinese legend of Shen Nong, the image portrays him using magical powers
to integrate enzyme/polyethyleneimine assembly structures, which mimics thylakoid
structures, into a microfluidic chip to convert CO2 into glucose precursor. This metaphor
symbolizes rice production, showcasing the reactor's exceptional activity, stability,
reusability, scalability, and potential for addressing CO2 emission and food shortage. More
