A gas-liquid interface in microfluidic devices requires effective gas absorption and minimal leakage. Here, we present porous polydimethylsiloxane (PDMS) as a gas-liquid interface for microfluidic applications. Two different porous PDMS structures, cube and film, have been prepared and tested for carbon dioxide (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) absorption ability in microfluidic devices. Porous PDMS showed higher CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> absorption rates compared with original PDMS thin films. We also demonstrated the utility of porous PDMS gas-liquid interface via artificial photosynthesis device. The experimental results indicated that the porous PDMS gas-liquid interface facilitates sufficient glucose synthesis by allowing effective CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> penetration.
