Two years ago the award-winning material Upsalite® was discovered by Maria Strømme and her team at the Ångström Laboratory in Uppsala. The material has recently been suggested as a drug delivery vehicle and as a topical bacteriostatic agent. In a just-published study the first in vivo acute systemic toxicity, skin irritation analyses and in vitro cytotoxicity evaluations of Upsalite® are presented.http://www.scirp.org/Journal/PaperInformation.aspx?PaperID=60282
