Overview

Experimental findings show surfactants restore optical properties in fluorescein, indicating potential for novel encryption methods.

Key Points

  • Fluorescence intensity increased by approximately 2150-fold at pH 1.0, restoring optical properties under acidic conditions.
  • Experimental characterizations and theoretical calculations revealed the role of surfactants in breaking aggregation-related quenching.
  • This innovation allows fast response of 1 second for a user-friendly multi-channel encryption system.
  • The system shows promise in applications for anti-counterfeiting and information encryption, highlighting its practical significance.
