Identification of Mycoplasmas Using a Fluorophore-Free Microarray and Infrared Chemical Imaging (IRCI).

Mossoba MM, Chizhikov V, Volokhov DV, Martinez-Diaz Milians K, Schoen B, Al-Khaldi SF


A novel application of mid-infrared chemical imaging (IRCI) for the fluorophore-free detection and identification of mycoplasma species is reported for the first time. The PCR-amplified biotinylated targets hybridized to microarray probes were treated with streptavidin-gold nanoparticles followed by silver enhancement. This modification has the potential to expand the implementation of DNA microarray techniques in laboratories involved in the detection of cell substrates, other biological products, and clinical materials for the presence of mycoplasmas.
