Abstract

Al nanohole array plasmonic biosensors have been fabricated on polycarbonate (PC) substrates from conventional 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.
