• To combine droplet microfluidics with light-sheet microscopy on a single chip.
• To enable rapid, three-dimensional imaging and quantitative analysis of samples.

Main Methods:

• A novel optofluidic device integrating droplet microfluidics and light-sheet microscopy was designed.
• The device features orthogonal plane illumination and rapid liquid handling for sample preparation.
• Droplets are automatically scanned by a laser-sheet for 3-D reconstruction and analysis.

Main Results:

• The device achieved high-throughput sample compartmentalization, manipulation, and 3-D imaging.
• It demonstrated tunable droplet size, frequency, and ingredient preparation.
• The platform achieved 500 measurements per second and screened over 30 samples per minute.

Conclusions:

• This compact and cost-effective optofluidic platform simplifies 3-D imaging and sample preparation.
• It eliminates the need for complicated mechanical scanning systems.
• The device shows significant potential for lab-on-a-chip applications like embryo sorting and cell growth assays.
