TechConnect 2018 an SBIR/STTR Haven

TechConnect #techconnect keeps getting better every year! Anaheim was a great location, with a good mix of entrepreneurs and investors! Looking forward to the next one in Boston in May 2019. I chaired a very engaging panel of experts who elaborated on the biggest problem facing the industrial production of uniform nanoparticles. I showcased Notre …

CD133+ Cancer Stem Cells Role in Metastasis

Excited for the 2nd publication this year through collaborative efforts with Harper Cancer Research Institute’s Karen Dahl (Title: CD133 Promotes Adhesion to the Ovarian Cancer Metastatic Niche). I did the 3D confocal imaging that showed CD133+ ovarian cancer cells clearly penetrate the basal epithelial cells, pointing to metastatic potential of stem cell like cancer cells. Looking …

Dual Mode CT/Fluorescence Detectable Immunotargeted Nanoparticle Probes to Identify Self-Renewing Cancer Cells In Vivo

Statement of Purpose: The high mortality and poor prognosis for women diagnosed with ovarian cancer is mainly due to late diagnosis. Improved detection of primary tumors and recurring tumors after chemotherapy is, therefore, crucial to reduce ovarian cancer mortality and improve progression-free survival. However, current clinical screening and diagnostic imaging methods are limited by low …

Cytocompatibility of Hafnium Oxide Nanoparticle Imaging Probes Prepared Using a Novel Templated Synthesis

This work will be presented at MRS 2018 and at SFB 2018 Statement of Purpose: Hafnium oxide (HfO2) with a k-edge of 50 keV is being explored as a clinical X-ray contrast agent. HfO2 NPs are also in clinical trials as radiosensitizers that induce immune action against tumor sites.   However, the unpredictable stability of commercially …

Non-Sintered Metal Oxide Nanocrystals

Nanoparticles (NPs) due to their size scale being 1-100 nm, are characterized by a greater surface area per unit mass than the bulk phase of the same material, which makes NPs display chemical reactivity and physical properties that approach the atomic phase. NPs derived from lanthanides (e.g. gadolinium, europium, etc.)  in particular attract a lot …
