The development of portable flexible sensors for sensitive gas detection with antibacterial activity is of great significance for protecting human health and environment safety. In this paper, we designed a ratiometric sensing platform (PLA@RPEG@TBSN) for reliable and visual monitoring of gaseous HO by electrospinning technology, which reveals self-antibacterial function and highly photostability simultaneously. By employing the aggregation-induced emission (AIE) active nanoparticles (TBSN) as fluorescent responder and Rose Bengal modified photosensitive polymer (RPEG) as reference unit, accurate ratiometric sensing process of PLA@RPEG@TBSN film was realized based on the specific peroxide-mediated reaction between TBSN and HO. The flexible film system demonstrated superiorsensingperformance toward HO vapor, including excellent selectivity, visualized color change and low detection limit (7 ppb). Additionally, benefitting from the photodynamic activity of RPEG, the PLA@RPEG@TBSN film exhibited highly effective antibacterial performance (killing 84 % of bacteria). Moreover, the multifunctional wearable potential is supported by employing film sensor onto the protective mask, which reveals dual capabilities of ratio sensing and resistance bacteria aerosols, encouraging the application of the sensor in complex practical scenario.
