• anodic porous alumina (tAPA) was fabricated from a 500 nm thick aluminum (Al) layer coated on silicon wafers, through single-step anodization performed in a Teflon electrochemical cell in 0.4 M aqueous phosphoric acid at 110 V. Post-fabrication etching in the same acid allowed obtaining tAPA surfaces

• of the use of tAPA–Au substrates as a platform for the development of surface-enhanced Raman spectroscopy (SERS) biosensors on living cells. In the future, these tAPA–Au-SLB substrates will be investigated also for drug delivery of bioactive agents from the APA pores. Keywords: anodic porous alumina

• ; SERS; nanopores; supported lipid bilayers; thiols; Introduction Anodic porous alumina (APA) is a layered material usually obtained in thick form (≈10 µm thickness scale) from electrochemical anodization in the acidic aqueous electrolyte of aluminum (Al) foils [1]. In APA, the control of pore size

• , following the success of nanostructured anodic porous alumina, anodic porous titania has also attracted the interest of academic researchers. This material, investigated mainly for its photocatalytic properties and for applications in solar cells, is usually obtained from the anodization of ultrapure

• , namely, anodic porous alumina (APA), which is mainly used in nanotechnology [8] because no particular pore order is required in this field. Here, a relatively uniform pore size and spacing is required and thus the preliminary electropolishing and two-step anodization used for APA to form hexagonal pore
