Abstract Extracellular matrix (ECM) proteins containing cell‐attachable Arg‐Gly‐Asp (RGD) sequences exhibit variable bridging and non‐bridging in fibronectin‐collagen laminin‐collagen complexes that can regulate inflammation, tissue repair, wound healing. In this study, linking molecule‐mediated conjugation of 1D magnetic nanocylinders (MNCs) to material surfaces pre‐decorated with gold nanospheres (GNSs) is performed, thereby yielding RGD‐coated MNCs (RGD‐MNCs) over GNSs (RGD‐GNSs) a state. The RGD‐MNCs are drawn closer the RGD‐GNSs via field‐mediated compression molecules establish between them.
