Recent developments have introduced the concept of Janus membranes-structures with asymmetric, dual-function surfaces-offering promising solutions to these challenges. While various reviews have addressed barrier membranes for periodontal and bone regeneration, comprehensive reviews specifically focusing on multifunctional Janus membranes are still limited. This review highlights recent advances in Janus membrane design for GTR and GBR applications.

Here, utilizing the H<sub>2</sub>O<sub>2</sub> generation capacity of doxorubicin (DOX), polyacrylic acid (PAA)/CuMnSe nanospheres (NSs) are designed for efficient delivery of DOX to the TME, promoting cuproptosis and CDT simultaneously.

The cations (Cu<sup>2+</sup>/Cu<sup>+</sup> or Mn<sup>4+</sup>/Mn<sup>2+</sup>) endow the NSs with cuproptosis and CDT activity, respectively, while CuMnSe acts as a photothermal agent, rendering the NSs near-infrared (NIR)-responsive. Controlled release of DOX in the TME rapidly elevates H<sub>2</sub>O<sub>2</sub> to accelerate two coupled redox reactions underpinning cuproptosis and CDT.
