Andreas Bernkop-Schnürch (born in Klagenfurt 6 December 1965) is an Austrian scientist and entrepreneur. He is Head of the Department of Pharmaceutical Technology, Institute of Pharmacy, University of Innsbruck. His research centers on the areas of drug delivery, dosage forms, controlled release, bionanotechnology, polymer engineering and tissue engineering. He is the inventor of several technologies such as thiolated polymers [1][2] for that he coined the name thiomers in 2000[3] and phosphatase triggered charge-converting nanoparticles for mucosal drug delivery.[4] Since 2014 he is on the scientific advisory board of the Nicotine Science Center,[5] Denmark. From 2016 to 2018 he served as a member of the Scientific Committee[6] of the Innovative Medicines Initiative (IMI) of the European Union in Brussels giving advice on scientific priorities to be included in the Strategic Research Agenda for Horizon 2020. He is member of the editorial board of numerous pharmaceutical journals including International Journal of Pharmaceutics, Journal of Drug Delivery Science and Technology, Scientia Pharmaceutica, Drug Development and Industrial Pharmacy and European Journal of Pharmaceutics and Biopharmaceutis. Andreas Bernkop-Schnürch is the founder of Thiomatrix Forschungs- und Beratungs GmbH, Mucobiomer Biotechnologische Forschungs- und Entwicklungs GmbH (now part of the Croma-Pharma GmbH) and Green River Polymers Forschungs und Entwicklungs GmbH. Since 2022 he is listed as a Highly Cited Researcher of the Institute of Scientific Information.[7]


Biography

Andreas Bernkop-Schnürch descends from an Austrian apothecary family. He was educated in pharmacy and in microbiology and genetics at the University of Vienna, finishing his doctorate in 1994. From 1994 to 1999 he was postdoctoral fellow at the Institute of Pharmacy, University of Vienna. In 1999, he applied to qualify as a professor by receiving the "venia docendi" in pharmaceutical technology. Since 2003 he holds the chair in pharmaceutical technology at the University of Innsbruck heading the Department of Pharmaceutical Technology.[8] From 2006 to 2013 he served as dean of the Faculty of Chemistry and Pharmacy.[9] In 2022 he was visiting professor at the University of Bari Aldo Moro. Since 2021 he is member of the senate of the University of Innsbruck.

Research

Andreas Bernkop-Schnürch is known for his research on drug delivery systems, multifunctional polymers, and tissue engineering. He invented and pioneered thiolated polymers – thiomers – as a new generation of bio- and mucoadhesive polymers forming disulfide bonds with cysteine-rich subdomains of endogenous proteins such as mucus glycoproteins or keratins.[1][2] Various medicines based on thiomers have already successfully passed clinical trials[10][11] and first products such as for treatment of dry eye syndrome have already reached the global pharmaceutical market.[12] He introduced thiolated polysaccharides as new biopolymers for tissue engineering at the 4th Central European Symposium on Pharmaceutical Technology in Vienna 2001 [13] resulting in numerous products containing thiomers such as thiolated chitosans or thiolated hyaluronic acid.[14][15] The thiomer-technology contributed also to the development of thiolated nanoparticles that are used as carriers for drug delivery, as diagnostics and as biosensorics.[16] The likely smallest thiolated nanocarriers for drug delivery are thiolated cyclodextrins that were introduced by him in 2015[17] providing in particular a prolonged residence time on mucosal membranes,[18][19][20] exhibiting permeation enhancing[21] as well as efflux pump inhibiting properties[22] and improving cellular uptake.[23] Furthermore, Andreas Bernkop-Schnürch pioneered charge-converting nanoparticles for mucosal drug delivery utilizing the membrane bound enzyme alkaline phosphatase to trigger a shift in zeta potential from negative to positive directly at the epithelium.[4] Cationic nanoparticles are more efficiently taken up by epithelial cells than anionic ones. However, they do not reach epithelial cells as they are immobilized via ionic interactions in mucus displaying an anionic charge because of sialic acid substructures. Charge-converting nanoparticles address this so-called ‘polycation dilemma’ by converting their surface charge to positive at the cellular membrane.[24] Moreover, Andreas Bernkop-Schnürch contributed basic knowledge to the field of self-emulsifying drug delivery systems (SEDDS) for mucosal delivery of macromolecular drugs.[25]
