title: An aptamer-based keypad lock system.
abstract: An aptamer-based security system mimicking keypad lock function was successfully designed. The system was turned "ON" with a strong fluorescent output signal only when the inputs were added according to the correct combination and exact sequence. Otherwise, the system was kept "OFF" to prevent illegal access.
