Abstract: Microarray patches are minimally-invasive delivery systems that painlessly and without drawing blood facilitate drug delivery into and across the skin. Traditionally, vaccines have been the main focus in the field. Our work instead concentrates on delivery of high doses of drugs. I will discuss how our technologies can potentially help address the HIV epidemic and also extend the useful lifetime of existing antibiotics. Bio: Professor Ryan Donnelly holds the Chair in Pharmaceutical Technology and is Director of Queen's University Belfast’s new £3 million pioneer research programme Materials & Advanced Technologies for Healthcare, comprising 55 academics from Pharmacy, Chemistry & Chemical Engineering, Mechanical & Aerospace Engineering, Biological Sciences, Nursing and Medicine. His personal research is centred on design and physicochemical characterisation of advanced polymeric drug delivery systems for transdermal and intradermal drug delivery, with a strong emphasis on improving patient outcomes. He is currently developing a range of novel microneedle technologies through independent research, but also in collaboration with several major pharma partners.
