Sialic Acid Activated Gold Nanoparticles as Rapid Affordable Reagent for Peste Des Petits Ruminants (PPR) Virus...

Animal health issues are important for farming community in agriculture. Small ruminant populations such as goats and sheep often get affected with contagious diseases. Peste des petits ruminants caused by a virus which need to be detected quickly to isolate affected animals and stop the spread of disease. The H protein of Peste des petits ruminants virus has sialic acid specific receptor, therefore sialic acid reduce and stabilized gold-nanoparticles were synthesize by a simple one pot method and without chemically modifying the sialic acid. The gold nanoparticles showed targetspecific aggregation with viral particles via hemagglutinin-sialic acid binding. The PPR virus was readily detected at the dilution of 10^-6 by sialic acid-AuNPs. While comparing with the standard monoclonal antibody based test used for the detection of Peste des petits ruminants virus, sialic acid-AuNPs gave detection faster in less than 2 minute.
