The development of a noninvasive method for the detection of Alzheimer's disease is of high current interest, which can be critical in early diagnosis and in guiding treatment of the disease. The aggregates of β-amyloid are a pathological hallmark of Alzheimer's disease. Carbohydrates such as gangliosides have been shown to play significant roles in(More)
Nanoparticles (NPs) are being extensively studied as carriers for drug delivery, but they often have limited penetration inside tumors. We envision that by targeting an endocytic receptor on the cell surface, the uptake of NPs can be significantly enhanced through receptor mediated endocytosis. In addition, if the receptor is recycled to the cell surface,(More)
We report that receptor mediated transcytosis can be utilized to facilitate tumor penetration by drug loaded nanoparticles (NPs). We synthesized hyaluronan (HA) coated silica nanoparticles (SNPs) containing a highly fluorescent core to target CD44 expressed on the cancer cell surface. Although prior studies have primarily focused on CD44 mediated(More)
The cell surface adhesion molecule CD44 plays important roles in the initiation and development of atherosclerotic plaques. We aim to develop nanoparticles that can selectively target CD44 for the non-invasive detection of atherosclerotic plaques by magnetic resonance imaging. Magnetic glyconanoparticles with hyaluronan immobilized on the surface have been(More)
