Increased neuritogenesis on ternary nanofiber matrices of PLCL and laminin decorated with black phosphorus

•Black phosphorus (BP)-functionalized PLCL and laminin nanofiber matrices are designed.•PLCL/Lam/BP nanofiber matrices favorably support the attachment and proliferation of hippocampal neurons.•PLCL/Lam/BP matrices can promote not only neurite outgrowth and alignment, but also increase neuritogenesis.•PLCL/Lam/BP matrices can be employed as potential scaffolds for neural tissue engineering and regeneration.
