Abstract :

Nanotechnology is bringing ground-breaking tools and new capabilities to biomolecule research and medical diagnosis. Gold nanoparticles as one of the most extensively studied nanomaterials, have many interesting and unique optical properties. These properties make gold nanoparticles as excellent optical probes for biomolecular imaging and assay applications. Based on the light scattering property of gold nanoparticles, our group has recently developed a nanoparticle-enabled dynamic light scattering assay (NanoDLSay) technology for biomolecular detection and analysis. This technique detects proteins, DNAs and other biomolecular targets by monitoring the size change of the gold nanoparticles caused by target analyte binding. In the last few years, we have investigated heavily on the use of NanoDLSay technique for cancer biomarker research. From our study, we made several new findings: (1) a prostate cancer biomarker, prostatic acid phosphatase (PAP), is significantly more complexed or aggregated in prostate cancer tissue than in the normal and BPH (benign prostate hyperplasia) tissue; (2) the concentration of certain serum protein-complexed VEGF (vascular endothelial growth factor) in blood serum is decreased in prostate cancer compared to normal and benign prostate conditions; and (3) we discovered a new protein complex from the nucleus of a pancreatic cancer cell line, Panc-1 . In this talk, we will explain the principle of NanoDLSay technology and its broad applications in cancer biomarker research.
