An oligonucleotide protected with N-(trimethylsilyloxycarbonyl) (Teoc) and P-(trimethylsilylethanol) (Tse) groups was synthesized and deprotected by a single ZnBr2 treatment. Finally it was released from the solid support by cleavage of a disulfide linkage with TCEP. The olgonucleotide was obtained without

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

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