General description

3,3′-Diethylthiacarbocyanine iodide (DTCI) is a cyanine dye, which acts as a donor in the electrochemical system. It can be used in the development of electrochemical cells.

Application

DTCI may be incorporated as a layer on gold nanorods, which can be used in surface enhanced resonance Raman spectroscopy (SERRS). It may be coated on a fused silica wafer, which can potentially be used in the development of solid state dye doped polymeric laser.

Fluorescence Quenching Microscopy: Imaging Two-Dimensional Materials

Developed in the last several years, fluorescence quenching microscopy (FQM) has enabled rapid, inexpensive, and high-fidelity visualization of two-dimensional (2D) materials such as graphene-based sheets and MoS2.

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.
