Abstract
An apparatus for determining an optical property of a set of cells is described. The apparatus may include a light source for providing a light signal, a light-conditioning unit configured to condition the light signal, and a diffractive structure. The diffractive structure may be configured to receive the conditioned light signal and produce diffracted light having plasmon-resonance properties and an angular spectrum. The angular spectrum may correspond to the set of cells when the set of cells are within a threshold distance from the diffractive structure. The apparatus further includes a light-collecting unit for collecting the diffracted light.
