General description

2,5-Diphenyloxazole (PPO) is an oxazole that can be used as a scintillator and a laser dye. It has fluorescence at a wavelength of 375 nm. It can be used as a wavelength shifter in liquid samples due to their high quantum yield and large strokes shift.

Application

PPO can be used as a dopant that improves the photo-electric feedback of plastic scintillators which are used as radiation detectors for nuclear materials. It can be coated on peptide substrates to facilitate radioactive labelling which can enable determination of substrate specificity of lysine methyltransferase enzymes. It may also be used in the fabrication of organic luminescent materials which can be used in light emitting diodes (LEDs).

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.
