Insights
A novel biosensor enables simultaneous detection of hepatitis B and C viruses (HBV and HCV) using particle counting and signal amplification. This sensitive method aids in diagnosing overlapping viral hepatitis infections.
Area of Science:
- Biomedical Engineering
- Infectious Diseases
- Nanotechnology
Background:
- Hepatitis B virus (HBV) and hepatitis C virus (HCV) are major causes of liver disease.
- Similar transmission routes increase the risk of co-infection and cross-infection.
- Accurate and sensitive detection methods are crucial for managing HBV and HCV infections.
Purpose of the Study:
- To develop a highly sensitive biosensor for simultaneous detection of HBV and HCV.
- To distinguish between HBV and HCV infections, including cases of overlapping infection.
- To provide a new diagnostic tool for viral hepatitis.
Main Methods:
- Utilized an Exo III assisted signal amplification strategy combined with particle counting technology.
- Employed dark-field microscopy for automatic particle enumeration.
- Leveraged colorful light scattering from plasmonic nanoparticles for detection.
Main Results:
- Achieved low limits of detection: 0.194 pM for HBV and 0.169 pM for HCV.
- Demonstrated the capability for simultaneous detection of both viruses.
- The assay showed high sensitivity and selectivity.
Conclusions:
- A novel biosensor, the "hepatitis virus indicator," was successfully developed.
- The method offers a simple, sensitive, and selective approach for simultaneous HBV and HCV detection.
- This technology presents a new strategy for early diagnosis of viral hepatitis, potentially applicable to other hepatitis viruses.
Abstract:
As the common hepatitis viruses, hepatitis B virus (HBV) and hepatitis C virus (HCV) are important causes of liver diseases, which greatly threaten human health and public hygiene. Furthermore, due to the similar transmission routes of HBV and HCV, it is highly susceptible to suffer from the cross-infection of HBV and HCV when humans are infected by hepatitis viruses. So it is urgent to develop strategies with high sensitivity to distinguish HBV/HCV and detect their overlapping infection. Herein, a new biosensor named "hepatitis virus indicator" for simultaneous detection of HBV and HCV based on the automatic particle enumeration was developed by the combination of Exo III assisted signal amplification strategy and particle counting technology with a dark-field microscopy. The limit of detections (LOD) were as low as 0.194 pM for HBV and 0.169 pM for HCV, respectively. In addition, the proposed method was capable of simultaneously detecting HBV and HCV based on the colorful light scattering from plasmonic nanoparticles. The proposed assay was simple, sensitive and selective for the simultaneous detection of HBV and HCV, which provided a new idea for the early diagnosis of diseases, such as hepatitis A virus (HAV), hepatitis D virus (HDV) and hepatitis E virus (HEV).
