제목 A Simple Route to Plasmonic Biosensor Array by Block Copolymer Lithography
초록 Highly uniform and dense, hexagonal noble metal nanoparticle arrays were achieved upon large-area transparent glass substrates via scalable, parallel processing of block copolymer lithography. Exploring their localized surface plasmon resonance (LSPR) characteristics revealed that Ag nanoparticle array displayed a UV-Vis absorbance spectrum sufficiently narrow and intense for biosensing application. A highly-sensitive, label-free detection of prostate cancer specific antibody (anti-PSA) with sub-ng/ml level detection limit (0.1 ~ 1 ng/ml) has been accomplished with the plasmonic nanostructure. Our approach offers a valuable route to low-cost, manufacturable-scale production of plasmonic nanostructures, potentially useful for various photonic and optoelectronic devices.
