DESIGNING AND SYNTHESIZING MULTIFUNCTIONAL NANOPARTICLES FOR THE INTRACELLULAR DELIVERY OF SOLUBLE CUES INTO CANCER AND STEM CELLS
One of the most important goals of molecular cell biology is to dissect the spatial-temporal interactions of biomolecules (or soluble cues) from the cellular to the integrated systems level. To investigate the complex interactions of soluble cues with cancer/stem cells and to study their specific effects on cancer/stem cell behaviors, we have developed multifunctional nanomaterial-based drug/gene delivery, molecular imaging techniques, and combined cancer/stem cell therapies. Potentially, nanoparticles, such as quantum dots, noble metallic nanoparticles, and magnetic nanoparticles (MNP), can circumvent or complement some of the limitations of conventional drug delivery and molecular imaging methods due to the unique physico-chemical properties of these nanoparticles. In our projects, we have addressed these issues by developing synthesis and labeling methods for different multifunctional nanoparticles.
