From Smartphone Assisted Sensing of Acid and Base Vapor to Antibacterial and Antibiofilm Activity: A Case Study of a FRET Pair Encapsulated Inside ZIF‐8
Year: 2026
Type: article
Abstract: In the current work, we investigated the Förster resonance energy transfer between an established pair of dyes fluorescein and rhodamine‐B encapsulated in ZIF‐8 metal organic framework (MOF) (RhB+Fl@ZIF‐8). The composite can successfully detect acid and base vapor within 10 min at ambient conditions, triggered by an optical change realized by the aid of a smartphone and a handheld UV torch. The change in color can be understood by any color matching applications available on the smartphone platforms. RhB+Fl@ZIF‐8 also shows considerable antibacterial activity (75.19%) whereas the individual composites of ZIF‐8 with fluorescein (63.81%) and rhodamine‐B (65.42%) showed lower improvement in antibacterial activity of pristine ZIF‐8 (66.64%). The current work opens up new avenues for designing multiutility MOF‐based materials for dual applications in optical sensing of acid and base vapor and as antibacterial agents.
