Negative Sense

LaCrosse (LAC) virus is a member of the California serogroup of the Bunyaviridae. The bunyaviruses are all negative-sense, RNA viruses whose genome consists of three segments of single stranded RNA. LAC virions are composed of multiple viral RNA strands complexed with viral nucleocapsid protein surrounded by a bilayer membrane embedded with 2 glycoproteins.Staining and drying of LAC virus samples produce images in which the virions are collapsed and distorted (Figure 1). Fixation prior to staining, also gives disappointing results, probably due to the high sensitivity of the LAC virus to changes in the ionic strength and composition of the solution in which it is suspended.

The Relationship

ABSTRACTIonically self-assembled monolayers have been recently shown to spontaneously produce the noncentrosymmetric ordering that is required for a second order nonlinear optical (NLO) response. The precise thickness of each monolayer is determined by variables such as the pH and ionic strength of the immersion solutions. We show here that the relationship between polymer conformation and layer thickness dramatically affects the magnitude of the NLO response. The largest χ(2) values are found in the thinnest films, indicating that the NLO response is determined primarily by chromophores located at the layer interfaces, as opposed to those within the bulk of a layer.
