Area of Science:

• Biotechnology
• Molecular Biology
• Medical Diagnostics

Background:

• Nucleic acid amplification tests (NATs) are crucial for pathogen detection but often require specialized equipment.
• Point-of-care NATs (POC-NATs) are needed for rapid diagnosis and treatment initiation.
• Existing POC-NAT systems like the Kaneka DNA chromatography chip (KDCC) face limitations in detection performance and amplification speed due to primer modifications.

Purpose of the Study:

• To identify improved primer modification substances for KDCC to enhance NAT system speed and performance.
• To develop a rapid herpes simplex virus detection system utilizing optimized KDCC technology.

Main Methods:

• Investigated various primer modification substances for KDCC.
• Evaluated amplification speed and detection performance of modified KDCC systems.
• Developed and tested a rapid herpes simplex virus detection system using azobenzene-modified primers.

Main Results:

• Azobenzene-modified primers demonstrated the highest amplification speed and detection performance among tested modifications.
• The new system achieved a 10-100 fold lower detection limit while maintaining reaction time.
• A rapid herpes simplex virus detection system was successfully developed.

Conclusions:

• Azobenzene modification significantly enhances KDCC performance, addressing limitations of previous primer modifications.
• This advancement facilitates faster and more sensitive POC-NAT, improving medical diagnostics.
• The developed system holds potential for wider POC-NAT utilization, particularly in resource-limited settings.
