摘要： The invention relates to a particle detection device and a method for detecting particles in a fluid by means of separation. A channel structure is arranged for separating an incoming flow into a major flow comprising a minor portion of particles above the first predetermined size and a minor flow comprising a major portion of particles above the predetermined size. One or more detectors are arranged for detecting particles in the major flow and minor flow. The channel structure further comprises a choked flow restriction arranged for enabling a constant flow independent of pressure conditions.

摘要： A device for the detection of analytes comprises a substrate (10) with nano-antennas (11,12). The nano-antennas (11,12) comprise an antenna material (11m, 12m) for forming resonant antenna structures which receive and resonantly interact with source light (L0) to form respective resonance peaks (R1,R2) over a resonant wavelength range (A1,A2) overlapping respective signature wavelength (λ1,λ2) of a target analyte (A). The resonant interaction causes a locally concentrated field (Ec) of the source light (L0) in the resonant wavelength range (Λ1,Λ2). The concentrated intensity (Ic) is localized around a respective target location (T1,T2) which is provided with a sorption material (11s, 12s) that sorbs the target analyte (A). This provides a locally increased analyte concentration (Ac) of the target analyte (A) coinciding with the locally concentrated field (Ec) of the source light (L0). Accordingly, the interaction of the source light (L0) with the target analyte (A) is enhanced.
