Electrospinning has been extensively used to construct tissue‐engineered scaffolds because of its ability to provide the fibrous scaffold with structurally analogous to the naturally occurring protein in the extracellular matrix of native tissues. In addition, the modification of scaffolds with bioactive molecules is beneficial as this can create an environment that consists of biochemical cues to further promote cell adhesion, proliferation, and differentiation. In the present contribution, we prepared and investigated the potential used of aligned electrospun poly(3‐hydroxybutyrate) (PHB) scaffold immobilized with bioactive molecule to serve as nervous scaffold. Laminin was successfully immobilized on the surface using covalent binding between functional groups of modified scaffolds and protein. The ability to use for neural regeneration was evaluated in vitro towards murine neuroblastoma Neuro2a cell line and mouse brain‐derived neural stem cells. The surface modification with laminin immobilized on the PHB fibrous scaffolds supported the attachment and promoted the proliferation of Neuro2a very wells. Despite the good attachment and proliferation of Neuro2a and mouse brain‐derived neural stem cells were not able to proliferate on the neat PHB, hydrolyzed PHB and laminin immobilized on hydrolyzed PHB fibrous scaffold.
