This seminar will describe imaging and therapeutic technologies in development in the Smith Lab at the University of Illinois. The imaging technologies focus on quantum dots, which are light-emitting nanocrystals that have been transformative for understanding single-molecule cellular processes and for measuring molecular biomarkers in clinical tissues. The Smith Lab engineers the photophysical and colloidal properties of quantum dots for counting and observing intracellular and plasma membrane proteins in living cells, to absolutely measure disease-associated molecules in clinical biospecimens, and to inform the development of new therapeutic modalities for cancer, Alzheimer’s, and obesity. The therapeutic technologies are based on translational drug-delivery vehicles for diseases related to inflammation, including cancer, obesity, and type 2 diabetes. These nanomaterials selectively target macrophages with extraordinarily high efficiency in inflamed tissues in mouse models of obesity, reaching up to 70% of the total injected dose, increasing the potency of anti-inflammatory therapeutics by 20-fold. This strategy may be widely adopted for the detection and treatment of diseases associated with macrophage-mediated inflammation.
