Abstract

A new fluorescence enhancement technical platform based on the lithographically patterned anodic aluminum oxide (AAO) nanostructures is reported for the first time. The fluorescence images of several types of fluorescent dyes on the AAO and Au-coated AAO substrates have been obtained and examined. Significant fluorescence enhancement has been observed. This type of AAO-nanostructure platform has potential applications, especially its integration with microdevices and microfluidic devices for fluorescence-based biological analysis.
