ACS AMA Hello Reddit! We are Sylvia Daunert, Suzana Hamdan, and Irena Pastar of the University of Miami Miller School of Medicine. In February 2017, we published our research in ACS Central Science, an open access journal, entitled “Nanotechnology-Driven Therapeutic Interventions in Wound Healing: Potential Uses and Applications” We look forward to answering your questions about this research today! To introduce ourselves, alphabetically by surname: I am Sylvia Daunert and I am the Lucille P. Markey Chair of Biochemistry and Molecular Biology, as well as the Associate Director of the Dr. JT Macdonald Biomedical Nanotechnology Institute at the University of Miami. My group’s research focuses on the development of bio-inspired nanotechnologies to solve biomedical and environmental problems. We genetically engineer living cells and proteins for environmental detection, molecular sensing, molecular diagnostics, point-of-care tests, biomarker identification, and targeted and responsive drug delivery. We recently developed a nanocarrier-based method for the targeted delivery of stem cells for wound healing. The technology, while widely applicable to a variety of wounds, was first demonstrated in diabetic wounds and in animal models of corneal and retinal injury. I was a Fulbright Scholar at the University of Michigan, and awarded my Ph.D. in bioanalytical chemistry at the University of Barcelona in Spain. I am Suzana Hamdan and I am a Postdoctoral Associate in the Daunert Research Group at the University of Miami Miller School of Medicine. My current research interests focus on the biological studies of nanomaterials derived from pharmaceutical drugs. In fall 2007, I received a Master of Science degree from East Tennessee State University, and was awarded a Ph.D. degree in May 2015 from the chemistry department at Louisiana State University. During my graduate studies, I developed novel techniques for size-control of nanoparticles derived from organic salts, and designed molecularly imprinted polymeric nanoparticles for chiral recognition of biological targets. I am currently the author of eight published scientific papers, with a special focus on nanotechnology and analytical chemistry fields. I am Irena Pastar and I am an Assistant Professor at the University of Miami, Department of Dermatology and Cutaneous Surgery. Our department has developed an unique wound healing research program focused on understanding the nature of non-healing wounds at the cellular and molecular levels. We have also been active in a variety of pre-clinical studies and clinical trials evaluating bioengineered products, drugs, dressings and devices important to wound repair. After receiving my Ph.D. in molecular microbiology and completing a postdoctoral fellowship in immunology at the Rockefeller University, I pursued translational research in cutaneous wound healing. My research focuses on the molecular pathophysiology of chronic wounds and cutaneous infections. I am a leading investigator and co-investigator on multiple federal and industry sponsored studies on novel wound healing therapeutics and chronic wound pathogenesis. Ask us anything about using nanotechnology to heal wounds! We will be back at 12pm ET (9am PT, 5pm UTC) to answer your questions. Hi Reddit! Sylvia, Irena, and I are online , and happy to answer your questions! Hello Reddit Users, We are logging off for a while, but will be back later to answer your questions. Thank you for your interest in our field! Irena, Suzana and Sylvia Hi Reddit! We are back online again and ready to answer more questions! We are logging off for now, we might answer few more questions later on. We would like to thank all who participated in our AMA Reddit today and apologize to those who did not get an answer due to a lack of time to get to all questions. Hope you continue your interest in nanotechnology and keep on supporting research. It is really important to us and our global scientific community! Thanks again, Suzana, Irena and Sylvia
