Abstract

Al nanohole array plasmonic biosensors have been fabricated on polycarbonate (PC) substrates from convention- al compact discs (CD). Standard micro and nanofabrication processes have been used and optimized to be PC compatible. The viability of this CD-based plasmonic platform for label- free optical biosensing has been demonstrated through a competitive bioassay for biotin analysis using biotin- functionalized dextran-lipase conjugates immobilized on the transducer surface.
