The first microfluidic synthesis of ionomer‐based bifunctional Janus supraballs possessing two distinct magnetic‐nanoparticle‐dropped and quantum dots–polymer hemispheres within an anisotropic structure is reported. Based on such Janus supraballs with stable fluorescence and superparamagnetism, a magnetoresponsive fluorescent switch is developed to realize free‐writing under a magnetic field. This is a promising, simple way to fabricate novel flexible bead displays.
