1. A support comprising a surface on which an assay for an analyte of interest can be performed, comprising:

  • an attachment layer comprising diamond-like carbon having sp2 and sp3 character on the support surface, wherein the attachment layer is adapted for capture of the analyte of interest for detection in the assay by binding the analyte directly to the diamond-like carbon; and

    an optically functional layer, an optical property of which is detectably altered upon a change in mass on said optically functional layer related to analyte binding, positioned on said support.
