Dengue is an emerging hemorrhagic fever virus and widely considered the most important arbovirus in the world. Dengue virus (DENV) is a positive-sense RNA virus that exists in 4, potentially 5, antigenic serotypes. Currently, no vaccines or treatments are approved for DENV infections. Unsuccessful vaccine trials open the door for non-traditional treatments such as silver nanoparticles. Silver nanoparticles (AgNP) are known to inhibit viral replication of numerous viruses but have never before been tested for inhibition of dengue virus type 2 (DENV2, ATCC® VR-1584TM). For the first time, this research presents up to a 96% reduction in DENV2 binding to Vero cells following pretreatment with AgNP (6-10nm, 25µg/mL). These results suggest that similarly to other viruses, DENV2 can be inhibited at the first stage of the virus replication cycle, binding & entry.
