Trends in Biosensors for HPV: Identification and Diagnosis

Figure 1

Schematic representation of a biosensor developed to detect HPV. The response arising from the biospecific interaction between the oligonucleotide probe and the HPV target DNA will be transduced into a measurable signal, which will be amplified and processed by computer software. The main types of signal transduction methods used in biosensors for HPV are optical, electrochemical, and piezoelectric. In addition, the signal conversion can be accomplished through SPR, EIS, and QCM techniques [31, 70, 103].
