Korean Researchers Develop Novel DNA Biosensor for Early Diagnosis of Cervical Cancer; Electrochemical Sensor Detects DNA of Human Papilloma Viruses HPV-16 and HPV-18 with High Specificity

Diagnosis of cervical cancer involves detection of target DNAs produced from human papillomavirus (HPV)-16 and HPV-18. Recently, researchers from Chung-Ang University in Korea developed an electrochemical DNA biosensor with enhanced sensitivity for effective HPV detection with high specificity. They achieved this feat using a graphitic nano-onion/molybdenum disulfide nanosheet composite with improved conductive electron transfer compared to the nanosheet alone. Their breakthrough can open doors to the development of electrochemical biosensors for early diagnosis of various ailments.
