Creative Diagnostics provides cadmium selenide (CdSe) semiconductor quantum dots with size-dependent emission range. Our CdSe quantum dots are core type II–VI semiconductor materials with size dependent optical/electronic properties, uniform size distribution and high quantum yield. The outer surface coating of organic ligands of CdSe quantum dots can be changed by ligand exchange process.

Silver nanoparticles have attract increasing attention for the wide range of applications in biomedicine. Silver nanoparticles, generally smaller than 100 nm and contain 20–15,000 silver atoms, have distinct physical, chemical and biological properties compared to their bulk parent materials.

Quantum dots (QDs) are often referred to very tiny man-made semiconductor particles, whose size are normally no more than 10 nanometers. Their extremely small size renders their optical and electronic properties different from those of bulk materials. A majority of QDs have the ability to emit light of specific wavelengths if excited by light or electricity.

Nucleic acid separation is an increasingly important technique in molecular biology. Various techniques have been developed in the past few decades. However, the traditional nucleic acid isolation methods have time- and work-consuming process based on several extraction and centrifugation steps. And they are often limited by small yields, low purities or low product concentrations.

Cell separation isolates cells according to their properties. Current researchers isolate cells to study the characteristics or biological processes of a certain cell population. Other applications, such as cell therapy, are also under rapid development. Several cell separation approaches have been developed. To know more about the magnetic assisted cell sorting, please visit Creative Diagnostics.
