Advances in early diagnosis of cervical cancer based on biosensors

Abstract

Human papillomavirus (HPV) is a causative agent of cervical cancer among women worldwide. Serological and molecular tests are commonly used to detect and identify HPV, but all the detection methods for HPV have some limitations. Nowadays, considerable advancements in nanosensors have enabled monitoring of hybridization procedures dynamically for HPV detection. Biosensors, as effective, quick, economical, and highly sensitive tools, can be used in the diagnosis of HPV as an alternative technique instead of other detection methods. Biosensor detection methods of HPV in use from 2000 to 2021 were investigated using several databases such as Google Scholar, Scopus, PubMed, and the Scientific Information Database. Furthermore, a manual search of the references of the retrieved articles was performed. On analyzing the most recently developed biosensors for HPV identification, we observed that three biosensor systems, electrochemical, optical, and piezoelectric systems, are the main transducers used in the development of HPV biosensors. The aim of this review is to examine recent research on biosensors for the detection of HPV and perform a comparison with other diagnostic methods.Considering the importance of rapid HPV detection in the control of infection and development of public health measures, improvement of biosensors as an economical and quick method can be very useful in the diagnosis of HPV.

“…Histologic evaluation of cervical biopsy is the basis for the diagnosis of cervical cancer [ 5 , 6 ]. The two most common histopathologic types of cervical cancer include squamous cell carcinoma (up to 85% of cases) and adenocarcinoma (up to 25%), including adenosquamous carcinoma and other histopathologic types (6%) [ 7 , 8 , 9 , 10 ].…”
