Speech title: Visualizing uptake of gold nanoparticles in live breast cancer cells and Zebra Fish

Abstract: Gold nanoparticles possess distinctive physicochemical properties and can be used as unconventional therapeutic approaches for targeting of cancer cells. However, the mechanism of the interaction between gold nanoparticles and cancer cells is still not clear. The purpose of this study was to grow gold nanoparticles with controlable particle sizes and use them to study their transport and diffusion in live breast cancer cells MCF-7 and zebra fish. We treated MCF-7 with 8 nm gold nanoparticles for 72 hours and visualized gold nanoparticles in the live cancer cells for different transport times. A dark field optical microscope (DFOM) was used to examine their transport and accumulation in the cancer cells as shown in Figure 1. Two concentrations of gold nanoparticles were tested in MCF7 cancer cells to determine the transport rate of the gold nanoparticles in the cancer cells. The results show that gold nanoparticles were able to enter not only cell membranes, but also nucleus of cancer cells. The transport or accumulation rate of gold nanoparticles in cancer cells was dependent on the time and the concentration of gold nanoparticles.

Biodata: Dr. Ju Chou is currently an Associate Professor in the Department of Chemistry and Physics at Florida Gulf Coast University. Dr. Chou received her Ph.D. in chemistry from Chinese Academy of Science, Changchun, China in 1995. After that, Dr. Chou has worked as a postdoctoral fellow in RIKEN Research Institute in Japan for a year during 1996-1997. She came to the United States as a visiting research scholar working at University of California-Irvine and later at University of California-Santa Barbara, respectively. Dr. Chou’s research areas include bio-electrochemistry of proteins such as cytochrome c, myoglobin and hemoglobin, bioaccumulation of trace elements in tissues, synthesis and characterization of nanomaterials such as gold nanoparticles and their biomedical applications. Dr. Chou’s recent research interests also include green synthesis of gold nanoparticles and environmental analysis of toxic metals in water, soil and human hair. She has also been collaborating with biology professors on the application of gold nanoparticles in biological systems such as cancer cells and zebrafish embryos. This research focuses on the design of model nanoparticles for potential application in in vitro and in vivo assays of studying toxicity, biocompatibility and transport of gold nanoparticles.

Title: Health and Performance Assessment using Nanocomposites + Tomography

Abstract: Biological systems, like structures, are susceptible to different types of damage and are influenced by changes in operating conditions. Lessons learned from structural health monitoring (SHM) can potentially help improve sensing and diagnostic capabilities in the biomedical domain. This presentation outlines a new paradigm shift in human health and performance monitoring, where sensors are designed from a materials perspective stemming from a “bottom-up” design methodology. In doing so, one can engineer multifunctional nanocomposites that possess a diverse suite of engineering functionalities, such as sensing of specific external stimuli (e.g., strain and pH). A few examples will be highlighted. The first case examines multifunctional graphene-based thin films engineered with electrical properties that are sensitive to strain for monitoring human motion and activity. A scalable fabrication method based on micro-plotting is proposed so that they are amenable to mass production, and sensor prototypes are validated for wearable sensing applications. In addition, by coupling the films with tomographic algorithms, these “sensing skins” are able to sense and localize features over large spatial domains. The second set of examples illustrate how one can leverage a different modality of electrical excitation to interrogate systems and characterize surface and subsurface changes in the biological system. Furthermore, nanocomposites embedded in the body, such as on implants and prostheses, then serve as passive elements that accentuate changes occurring in the tissue or human body (e.g., due to infection). A noncontact tomography algorithm and interrogation system is shown to map electrical property changes within the material, thereby enabling noncontact, noninvasive, surface and subsurface sensing. Numerical modeling and experimental results are presented.
