Explore the Infinite Possibilities of Lex-QD Nanoparticles with Us

We are committed to providing comprehensive Lex-QD nanoparticle production services to our clients worldwide, covering but not limited to:

Custom Synthesis

In our lab, we use a single-step solution method to synthesize cadmium sulfide nanocrystals functionalized with Lex (Galb1-4[Fuca1-3]GlcNAc). Moreover, we provide QD nanoparticle design and synthesis services with specific glycan structure, QD size, and surface modification. For example, we provide QD nanoparticle production service for the co-functionalization of disaccharide maltose (Glca1-4Glc) and trisaccharide antigen Lex.

Results: In this study, the researchers present the synthesis and characterization of QD nanoparticles modified using specific molecules and their application in cellular uptake. The researchers used a two-phase system and a combination of sonicated emulsions to prepare the biohybrid nanoparticles. Moreover, it was found that these synthesized biohybrid nanoparticles have the ability to be selectively targeted and delivered to specific cell types with good traceability.
