Multichannel piezoelectric genesensor for the detection of human papilloma virus.

Objective: To establish a method for rapid detection and sub-typing of human papilloma virus (HPV).

Methods: We utilized the piezoelectric genosensor (PG) technique, which is a combination of the piezoelectric biosensor and gene chips for HPV identification in 22 recurrent biopsy specimens and 22 corresponding original biopsy specimens. The control samples came from normal tissue of healthy persons.
