A method which involves or potentially involves organically-substituted silica particles in desorption of an adsorbate in a liquid medium, other than a method which is at least part of a process for making said silica particles. In some processes, which an analyte displaces a detectable substance, e.g. a dye, from organically modified/hydrophobic silica particles for which the analyte has affinity. Direct or indirect determination of the occurrence or amount of desorption may be used to provide a measure of the presence or amount (e.g. concentration) of analyte. Other processes comprise desorption of an analyte from organically modified/hydrophobic silica particles by elution, without displacement of a detectable substance from the particles. The methods may comprise one or more further activities, for example for determining the presence and/or amount of the analyte. |
