Abstract
Microplasma arrays and channels fabricated on plastic substrates by replica molding are well suited for biomolecule detection in liquid flow streams. Arrays of orthogonally oriented linear channels with cross-sectional areas of 100 × 100 μm2 have been operated in Ar/3% N2 gas mixtures at atmospheric pressure. Similar experiments with arrays of parallel linear channels having cross-sectional areas of 200 × 100 μm2 and lengths of 6 cm have also been conducted. Spatially uniform emission in the near ultraviolet (λ ∼300-400 nm) from the microcavity plasma sources and the photoluminescence of organic molecules in solution in adjoining channels have been observed.
