Quenching influence of cell culture medium on photoluminescence and morphological structure of porous silicon

► Porous silicon was prepared by stain-etching using a HF:HNO3 solution. ► Photoluminescence of porous silicon under the influential actions of cell culture medium was studied for degradation effects. ► B50 rat hippocampal neuron cell was cultured over visible photoluminescent porous surfaces. ► Porous silicon was used for direct culturing over nanostructured morphology.
