Extended Data Fig. 1: Fabrication of microfluidic chips and characterization of ferrobotic operations.
From: Ferrobotic swarms enable accessible and adaptable automated viral testing
a, Fabrication process of the microfluidic chip (e.g., individual testing chip). b, Optical images of ferro-droplet-carrying ferrobots at Δt = 0.25 s, visualizing the maximum achievable transportation velocities within different oil environments. In all cases, the ferrobots are programmed to travel at the highest possible velocity that allows for the ferro-droplets to keep up with the underlying ferrobot movement. c, Optical images of the arrays of aliquoted droplets for different corrugated opening widths. d, Relationship between the ferro-droplet diameter and volume. Insets show optical images of the ferro-droplets.
