Programmable Delivery: Multifarious Transit Gates for Programmable Delivery of Bio‐functionalized Matters (Small 28/2019)

In article number 1901105, CheolGi Kim and co-workers develop the multifarious transit gates of return, delay, dividing, and rectifying functions for micro-robotic carriers on versatile magnetic pathways. The “0” or “1” binary encoding for bifurcation transit is enabled by the pulsed z-field during the gating time zones in addition to rotating the 2D field for forward transporting of the carriers. The proposed approach provides a novel magnetophoretic platform for the programmable navigation of bio-functionalized matters and living cells.
