Abstract
An optofluidic antenna device () for shaping a light field of sample light emitted or scattered by a sample () comprises a substrate () and a liquid layer () being supported by the substrate () and being arranged for accommodating the sample () to be investigated between a first liquid surface () facing to the substrate () and a second liquid surface () opposite to the first liquid surface (), wherein a thickness of the liquid layer () between the first and second liquid surfaces () and refractive indices of the substrate () and the liquid layer () are selected such that an optofluidic antenna is formed, which is capable of directing the sample light mainly towards the substrate (), and a gas volume () is arranged above the liquid layer (), so that the second liquid surface () is formed as a liquid-gas-interface. Furthermore, a measuring apparatus (), that comprises the optofluidic antenna device (), and a method of detecting at least one photon emitted or scat-tered from a sample (), in particular a single analyte in a liquid, are described.
