We developed a polymerase reaction free, low-cost and sensitive assay for the colorimetric detection of Human Papilloma Virus (HPV), based on the use of a smart design exploiting magnetic microbeads, chimeric RNA/DNAzyme oligonucleotides, and double signal amplification. This method allows obtaining a fast response with a detection limit of 10 pM, avoiding the amplification of the target via traditional PCR.
