Speckle-microscopy is used for the detection of Chlamydia trachomatis in aqueous suspensions or on slides. Monoclonal antibody tagged with gold nanoparticles that form biospeckles have also been used with a small number of scatterers. By devising a prototype of laser scanning speckle-microscope, we now demonstrate that the signal of speckle microscope can be significantly amplified in the presence of gold nanoparticles. This enhancement of signal emitted from gold nanoparticles offers a better approach to the detection of C. trachomatis.
