제목 A Conical-Shape Ag Nanoparticle Array for Localized Surface PlasmonResonance Biosensor via Block Copolymer Lithography
초록 Highly uniform and dense, conical-shape 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 characteristics revealed that Ag nanoparticle array displayed a UV-vis absorbance spetrum sufficiently narrow and intense for biosensing application. A highly-sensitive, label-free detection of prostate cancer specific antibody with sub-ng/ml level detection limit has been accomplished with the plasmonic nanostructure. Our nanofabrication process offers a valuable route to low-cost, manufacturable-scale production of plasmonic nanostructures, potentially useful for various photonic and optoelectronic devices.
