Applicability of Metal Nanoparticles in the Detection and Monitoring of Hepatitis B Virus Infection

Maxim Shevtsov et al. Viruses. .

Abstract

Chronic infection with the hepatitis B virus (HBV) can lead to liver failure and can cause liver cirrhosis and hepatocellular carcinoma (HCC). Reliable means for detecting and monitoring HBV infection are essential to identify patients in need of therapy and to prevent HBV transmission. Nanomaterials with defined electrical, optical, and mechanical properties have been developed to detect and quantify viral antigens. In this review, we discuss the challenges in applying nanoparticles to HBV antigen detection and in realizing the bio-analytical potential of such nanoparticles. We discuss recent developments in generating detection platforms based on gold and iron oxide nanoparticles. Such platforms increase biological material detection efficiency by the targeted capture and concentration of HBV antigens, but the unique properties of nanoparticles can also be exploited for direct, sensitive, and specific antigen detection. We discuss several studies that show that nanomaterial-based platforms enable ultrasensitive HBV antigen detection.

Schematic representation of magnetic nanoparticle (MNP) clustering in the presence of a specific antigen. Following interaction between functionalized MNPs and an antigen, the clustering of MNPs induces a change in the T2 relaxation values of the surrounding water molecules, which can be detected by (diagnostic) magnetic resonance.
