Bio-bar-code dendrimer-like DNA as signal amplifier for cancerous cells assay using ruthenium nanoparticle-based ultrasensitive chemiluminescence detection

Bio-bar-code dendrimer-like DNA (bbc-DL-DNA) is employed as a label for the amplification assay of cancer cells in combination with the newly explored chemiluminescence (CL) system of luminol-H(2)O(2)-Ru(3+) and specificity of structure-switching aptamers selected by cell-based SELEX.
