Nonlinear immunofluorescent assay for androgenic hormones based on resonant structures

Opt Express. 2008 Aug 18;16(17):13315-22. doi: 10.1364/oe.16.013315.

Abstract

We report for the first time the use of two photon fluorescence as detection method of affinity binding reactions. We use a resonant grating waveguide structure as platform enhancement for detecting the interaction between fluorescent labeled Boldenone, a non-natural androgenic hormone, and a specific anti-anabolic antibody. We were able to detect a surface coverage of approximately 0.7 ng/mm(2).
