The changes in the optical and electronic properties of the materials due to the quantum confinement effect in semiconductor nanoparticles have attracted huge interest in the scientific community. Within the semiconductor nanoparticles, the quantum dots (QDs) deserve a special position due to their high quantum confinement effect and unique optoelectronic properties. Among the semiconductor quantum dots, CdTe attracts more attention due to its easy manufacturing, large Bohr exciton radius, and wide range of absorption and emission tunability. These unique properties make them useful in a wide range of areas, like solar cells, sensing, bioimaging, lasing, nonlinear optical applications, etc. In the present work, MSA-capped water-soluble CdTe QDs are prepared using a simple colloidal method for cell imaging. The XRD spectrum, UV-vis absorption spectrum, PL spectrum, DLS analysis, and HR-TEM analysis are applied for the characterization of synthesized CdTe QDs. Here, we synthesized red emissive spherical CdTe QDs of average size 6nm. The bioimaging efficiency of MSA-capped CdTe QDs is examined on N2A Cells. These results show that CdTe QDs are a promising material for cell imaging.
