______ WelcomePROGRAM Letter Dear Attendee of NEMB2018: On behalf of the organizers, we would like to welcome you to Los Angeles to the 6th American Society for Mechanical Engineers (ASME) NanoEngineering in Medicine and Biology Conference (NEMB 2018). At this meeting, you will have the opportunity to discuss the most recent advances in nanobiotechnology and nanomedicine with luminaries and pioneers of the field. Whether it’s a tutorial, plenary, keynote and theme presentation, a poster presentation, or a social event, we believe that you will enjoy these exciting elements of the conference. We hope you will benefit from the academic and industrial breadth of the meeting. Applications of Nanoengineering for medicine and biology are having a dramatic impact on a myriad of healthcare needs, product development and biomedical research. These include nanoparticle-based imaging probes and drug/gene carriers for new and improved disease diagnostics and therapeutics, bio-inspired nanomaterials and nanostructures, and novel Nanoengineering tools for biologicalConference and medical applications. | August These 21-24, frontiers 2018 of engineering, biology and medicine at the micro- and nano-scale will be highlighted at NEMB 2018. In addition, work contributing to completely new fundamental understandingExhibition of |biological August processes 22-23, and2018 phenomenon at the nanoscale will also be presented. Together these fundamental and applied aspects of the meeting provide the basis for solving grand challenge problems in cancer, infectious disease, cardiovascular, neurological diseases and global health. NanoengineersOMNI and Los nanoscientists Angeles areHotel indeed, changing the world and are having a profound impact on medicine and biology! California Plaza, We would like to acknowledge support for the conference from the National Science Foundation, Purdue University, WashingtonLos Angeles University ,at CA St. Louis, University of California, Irvine, University of Minnesota, and many generous funders acknowledged on our website and in our program. We would also like to acknowledge and highlight the many volunteers who helped assemble the scientific program for this conference especially our Steering Committee (Professors Abe Lee, Bumsoo Han, John Bischof, Guy Genin, Gang Bao), the Tutorial Speakers and Participants, Track Chairs, and Poster Awards committee (led by Zhenpeng Qin and Masaru Rao). You will see that amongst the Plenary and Keynote Speakers, Track Chairs and other attendees many are leading figures in the field. In addition to stimulating scientific and technical discussions, there will be ample opportunities for networking, especially for young researchers to mingle with senior investigators. Showcasing cutting edge research in Nanobioengineering with broad participation constitutes the heart of this meeting, as evident by how the talks, sessions, and tracks are constructed in the technical program. Finally, working hard behind the scenes is a devoted staff of technical assistants from ASME. The latter includes lead organizer extraordinaire Christine Reilley, Program Manager – Kanupriya Parasher and Webtool Coordinator – Laraine Lee. We wish you a productive and enjoyable stay in Los Angeles. Please stay tuned for information about the next NEMB conference!

In addition, we provide evidence that in vivo biodistribution of dCNTs is tunable by altering physical and chemical properties. TRACK 1 Stability and nontoxicity of dCNTs are essential for successful utilization in biological Nano/micro therapeutics and drug delivery systems. Long-term colloidal stability of dCNTs was evaluated by analyzing zeta po- tential (-40 to -50 mV) and physiological compatibility was optimized for ionic, systems high-serum environments. Cytotoxicity of dCNTs was evaluated in several murine and human cell-types, including prostate and myeloma cancer cell lines, as well as normal MSCs. Critically, dCNTs were found not found to elicit cytotoxicity in therapeutical- Track Organizer: Xiaoming He, University of Maryland, College Park, MD, Unit- ly-relevant concentrations.
