General description

Benzyl viologen dichloride (BVD) is an electrochromic indicator, which contains two chlorine atoms and an organic constituent attached with two nitrogen cations. In a redox reaction, BVD can be reduced in three states with different colors.

Application

BVD can be reduced to its neutral state by using sodium borohydride, which forms an n-type dopant for organic semiconductor based applications. It may be introduced to form a path for the transport of electrons from the thylakoid membranes to the mediator, which can be used in the fabrication of photo-driven bioanode. It also acts as a dopant with 2D layered materials to form an n-type chemical dopant that can be used to enhance the electrical properties of the triboelectric devices.

Graphene in Biotechnology

Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
