An Elegant Analysis of White Spot Syndrome Virus Using a Graphene Oxide/Methylene Blue based Electrochemical Immunosensor Platform

White spot syndrome virus (WSSV) is a major devastating virus in aquaculture industry. A sensitive and selective diagnostic method for WSSV is a pressing need for the early detection and protection of the aquaculture farms. Herein, we first report, a simple electrochemical immunosensor based on methylene blue dye (MB) immobilized graphene oxide modified glassy carbon electrode (GCE/GO@MB) for s...

Using Boehmite Nanoparticles as an Undercoat, and Riboflavin as a Redox Probe for Immunosensor Designing: Ultrasensitive Detection of Hepatitis C Virus Core Antigen

In this study a label-free electrochemical Immunosensor for ultrasensitive detection of Hepatitis C virus core antigen in serum samples was fabricated by using a simple approach. In this method a low-cost and sensitive immunosensor was fabricated based on a boehmite nanoparticles (BNPs) modified glassy carbon. The BNPs provide a specific platform with increased surface area which is capable of ...

Influenza virus immunosensor with an electro-active optical waveguide under potential modulation.

Here we report the development of a novel immunosensor-based strategy for label-free detection of viral pathogens by incorporating a sandwich bioassay onto a single-mode, electro-active, integrated optical waveguide (EA-IOW). Our strategy begins with the functionalization of the electro-active waveguide surface with a capture antibody aimed at a specific virus antigen. Once the target antigen i...

Polyclonal Antibody against Recombinant Nucleoprotein of the Influenza A Virus (H1N1); Production and Purification

Background and Aims: Influenza is an acute respiratory illness that is caused by a virus belonging to Orthomyxoviridae family. This virus spreads rapidly every year in cold season and leads to morbidities and mortalities especially in adults and children, which causes billions of dollars of economic losses. Accordingly, development of a rapid, sensitive and inexpensive laboratory diagnosis base...
