We report a strategy for using magnetic Janus microparticles to control the stimulation of T cell signaling with single-cell precision. To achieve this, we design Janus particles that are magnetically responsive on one hemisphere and stimulatory to T cells on the other side. By manipulating the rotation and locomotion of Janus particles under an external magnetic field, w e control the orientation of the particle-cell recognition and thereby initiation of T cell activation. This study demonstrates a step towards employing anisotropic material properties of Janus particles to control single cell activities without the need of complex magnetic manipulation devices.
