Urinary human papillomavirus DNA detection using piezoelectric biosensor

Cervical cancer is a disease that remains a concern for women worldwide. Despite the implementation of standard Pap test and the HPV test, the screening coverage is still low due to its invasive nature as both involve the collection of cervical samples. The HPV screening test itself is expensive, ex...
