Visual detection of HPV16 using a photoactivatable CRISPR-Cas12 system

Area of Science:

• Biotechnology
• Molecular Diagnostics
• Oncology

Background:

• Cervical cancer screening relies on accurate human papillomavirus (HPV) detection.
• Current methods may lack the speed and portability for widespread on-site use.

Purpose of the Study:

• To develop a simple, rapid, and convenient method for visualizing HPV16 detection.
• To explore the potential of photoactivated CRISPR-Cas12a combined with RPA for point-of-care diagnostics.

Main Methods:

• Utilized photoactivated CRISPR-Cas12a technology.
• Integrated a tube-in-tube structure with recombinase polymerase amplification (RPA).
• Enabled visualization detection under blue UV light (302 nm).

Main Results:

• Successfully demonstrated visualization detection of HPV16.
• The combined system offers a rapid and convenient detection method.
• The assay is facilitated by blue UV light, simplifying visualization.

Conclusions:

• The developed CRISPR-Cas12a and RPA system is a promising tool for HPV16 detection.
• This method has potential for on-site cervical cancer screening due to its portability and speed.
• Further development could enhance accessibility to HPV diagnostics.
