title: Tomato bushy stunt viruses (TBSV) in nanotechnology investigated by scanning force and scanning electron microscopy.
abstract: Spherical plant viruses like the tomato bushy stunt virus (TBSV) allow for multiple applications in nanotechnology due to their shape. In this article, different types of the virus were created by extending coat protein (CP) at carboxylic termini with 2 different charged amino acids by point mutation. The obtained CPs carried 6 aspartic acid (negative charge) and 4 histamine (positive charge) residues. The ability of TBSV to form self assembled monolayers with large ordered areas on native and chemically modified mica will be presented. The structural differences between layers formed by the wild type and by the genetically modified types will be discussed in detail.
