Abstract

The invention relates to a method for the detection of target components that comprise label particles, for example magnetic particles (). The method includes (a) collecting the target components at a binding surface () of a carrier (); (b) directing an input light beam (L, L, L) into the carrier such that it is totally internally reflected in an investigation region () at the binding surface (); and (c) determining the amount of light of an output light beam (L, L, L) that comprises at least some of the totally internally reflected light. Evanescent light generated during the total internal reflection is affected (absorbed, scattered) by target components and/or label particles () at the binding surface () and will therefore be missing in the output light beam (L). This can be used to determine the amount of target components at the binding surface () from the amount of light in the output light beam (L, L, L). A magnetic field generator () is optionally used to generate a magnetic field (B) at the binding surface () by which magnetic label particles () can be manipulated, for example attracted or repelled.
