## Abstract

This study introduces
a direct fluorescence-based molecular beacon
method to monitor droplet assembly in real-time, enhancing the precision
of synthetic biology and mesoscale material applications. Unlike traditional
imaging techniques, such as Pearson correlation from microscopic images,
the direct method allows continuous quantification of dynamic droplet
interactions with high sensitivity. This system utilizes single-stranded
DNA (ssDNA) beacons that fluoresce upon binding with complementary
ssDNA sequences in adjacent droplets, enabling the specific detection
of assembly events. The ability to manipulate assembly accurately
expands potential applications including the design of programmable
cellular mimics, biosensors for environmental monitoring, and smart
drug delivery systems that respond to specific cellular cues.
