However\, significant concerns a bout their toxicity have hampered progress in this area as most quantum do ts contain heavy metals like cadmium and lead. The potential of semiconduc tor quantum dots in bioimaging and sensing applications is therefore yet t o be optimized. Meanwhile\, luminescent quantum dots with their heavy meta ls have been incorporated into broadly distributed consumer electronics in cluding cell phones\, tablets\, TVs and light emitting displays\, and into solar energy and photovoltaic devices. This raises significant concerns a bout the potential adverse impact of luminescent quantum dots on living or ganisms in the environment\, particularly when these devices are disposed at the end of their lifetime. This presentation will focus on the unique l uminescent properties of semiconductor quantum dots as bioimaging and sens ing probes\, as well as on recent efforts to synthesize cadmium-free lumin escent quantum dots with comparable functional properties to cadmium-conta ining quantum dots\, but with significantly reduced impact on living organ isms. The potential application of luminescent quantum dots as antibacteri al agents when combined with synthetic mimics of antibacterial peptides wi ll also be described.\n\n\nDr. Rosenzweig obtained his BSc and PhD in Chem istry from the Hebrew University of Jerusalem in 1986 and 1992\, respectiv ely. Following three years of postdoctoral training at Iowa State Universi ty and the University of Michigan\, he joined the Department of Chemistry at the University of New Orleans where he developed a leading research pro gram in the area of luminescent biosensors. Dr. Rosenzweig served as Progr am Director in the US National Science Foundation Division of Chemistry be tween 2005 and 2014. He then joined the University of Maryland Baltimore C ounty as a Full Professor and Department Chair in the Department of Chemis try and Biochemistry\, where he developed a research and training program in the area of luminescent semiconductor quantum dots and their impact on natural systems.\n\nThis event is cohosted by the 9IÖÆ×÷³§Ãâ·Ñ Sustainabilty Sys tems Initiative (MSSI) and the Trottier Institute for Sustainability in En gineering and Design (TISED)\n\n \n DTSTART:20191025T143000Z DTEND:20191025T160000Z LOCATION:Room 160\, Arts Building\, CA\, QC\, Montreal\, H3A 0G5\, 853 rue Sherbrooke Ouest SUMMARY:Invited Speaker: Dr. Zeev Rosenzweig URL:/mssi/channels/event/invited-speaker-dr-zeev-rosen zweig-301886 END:VEVENT END:VCALENDAR
