Nanoporous Anodic Alumina Barcodes: Toward Smart Optical Biosensors
Advanced Materials, 2012 Toward a smart optical biosensor based on nanoporous anodic alumina (NAA): by modifying the pore geometry in nanoporous anodic alumina we are able to change the effective medium at will and tune the photoluminescence of NAA. The oscillations in the PL spectrum are converted into exclusive barcodes, which are useful for developing optical biomedical ...

Pecularities of tubular anodic alumina formation
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The formation conditions of anodic alumina with a tubular structure have been investigated. It is shown that alumina has the self-ordered tubular structure at temperature of barrier oxide layer to be several tens of degrees more than electrolyte ...

Chemical analysis of a single basic cell of porous anodic aluminium oxide templates [PDF]
, 2010 We prepared anodic aluminium oxide (AAO) templates with “honeycomb” geometry, i.e. hexagonally ordered circular pores. The structures were extensively studied and characterized by EPMA coupled with FEG-SEM and FEG-TEM coupled with EDX at meso and ...
