Abstract Immunological synapse (IS) is a complex supramolecular structure formed at the interface between T cells and antigen presenting cells (APCs) during T cell antigen recognition. Microfabricated platforms have made great contributions to our understanding of the assembly dynamics and functional roles of the T cell synapses over the last decade. Here, we review three different types of microfabricated platforms developed to modulate and monitor the T cell synapse assembly. Firstly, multi‐protein micropatterned surfaces presenting key ligands for T cell activation that can modulate the spatial distribution of receptors/signaling molecules in T cell synapses are described. Secondly, micropatterned supported bilayers that can modulate the dynamics of T cell receptor (TCR) microclusters are introduced. Lastly, T‐APC pair arrays that allow for improved fluorescence live cell imaging are discussed.
