Herpes simplex virus type-1 attachment inhibition by functionalized graphene oxide

Area of Science:

• Bioscience and Biotechnology
• Nanomaterials Science
• Virology

Background:

• Graphene oxide (GO) and its derivatives are gaining attention in bioscience.
• Herpes simplex virus type-1 (HSV-1) poses significant health challenges.
• Understanding viral entry mechanisms is crucial for developing antivirals.

Purpose of the Study:

• To investigate the antiviral potential of graphene oxide derivatives against HSV-1.
• To explore the mechanism of GO derivatives in inhibiting HSV-1 infection.
• To assess the safety and applicability of GO derivatives for biomedical purposes.

Main Methods:

• Synthesis and characterization of graphene oxide derivatives.
• In vitro assays to evaluate HSV-1 inhibition by GO derivatives.
• Mechanism studies involving cell surface receptor mimicry and viral binding.
• Cytotoxicity assessments of GO derivatives on host cells.

Main Results:

• Graphene oxide derivatives demonstrated significant inhibition of HSV-1 infection.
• The inhibition mechanism involves GO derivatives competing with heparan sulfate for HSV-1 binding.
• HSV-1 cell-to-cell spreading was not affected by the GO derivatives.
• The nanomaterials exhibited no cytotoxic effects on the cells.
• Media composition influenced the antiviral efficacy of the GO derivatives.

Conclusions:

• Graphene oxide derivatives show promise as effective antiviral agents against HSV-1.
• The findings suggest potential applications in developing antiviral surfaces and diagnostic tools.
• The non-cytotoxic nature of GO derivatives supports their biomedical potential.
