Fabrication of long-range surface plasmon-polariton Bragg gratings with microfluidic channels in Cytop claddings

Silicon photonic biosensors

“…In the field of silicon integrated microphotonic biosensors, plasmonic MIM waveguides can be used for demonstrating strongly miniaturised sensors exhibiting a resolution compliant with a wide range of emerging medical applications [51,52].…”

Selective detection of bacteria in urine with a long-range surface plasmon waveguide biosensor

“…A thick layer of photoresist was deposited onto the wafer before it was sent for dicing into ∼300 dies per wafer. The detailed fabrication process of the sensors was described in previous work [15,16]. A microscope image under 50 magnification of a portion of a die after experimentation is shown in Fig.…”

“…Test devices are manufactured in a wafer-based fabrication process [15,16] and are interrogated by a laser-based test system [17]. Injecting the content of syringes in the fluidic channel of the test device, the biosensing area is exposed to attachment chemistries then antibodies to functionalize the surface in preparation for a test.…”

Transmission light property due to grating-coupled long-range surface plasmon resonance

“…LRSPR has been used with grating coupling [13,14]; however, the property of transmission light due to LRSPR (T-LRSPR) has not been reported. In this study, T-LRSPR was initially investigated for BK-7 glass substrate/fluoropolymer CYTOP [15] with a grating structure/metal film/pure water system. T-LRSPR property changes were also observed with layer-by-layer (LbL) film deposition.…”
