A new type of labeling, quantum dot labeling (QD), has attracted a lot of attention recently. QD is a type of fluorescent semiconductor nanocrystal with unique optical and electrical properties due to its quantum effect and size effect. It has been widely used in many fields of life science. As an expert in protein research, Profacgen focuses on the research of nanotechnology and physicochemical properties of quantum dots. Leveraging its great value in optical and biological aspects, we offer a wide range of QD conjugation strategies to meet the specific requirements of your project.
