Micro- and Nanostructures for Oral Drug Delivery and Sensing

Anja Boisen
(DTU Nanotech) 

Micrometer sized containers can be used for oral drug delivery. The containers will protect active pharmaceutical ingredients during the passage through the stomach and facilitate adhesion to the wall of the intestine for controlled and unidirectional release, followed by absorption through the intestine. We will show our recent findings and results in the areas of microfabrication of containers, loading of drugs, pH sensitive lids and in vitro/in vivo testing.

Using the optics and/or mechanics from a DVD player, we can realize compact and sensitive sensor systems. By rotating a disc with integrated microfluidic channels it is possible to manipulate liquid samples such as blood and perform crucial operations like separation, valving and mixing. We integrate a variety of sensors with centrifugal microfluidics. Examples of applications include rapid diagnostics, prognostics, food analysis and studies of thermal properties and degradation of polymers.

Anja Boisen is professor and head of the Nanoprobes research group at Department of Micro and Nanotechnology, DTU, where she heads the research center on Intelligent Drug Delivery and Sensing.  After undergraduate work at the Universities of Roskilde and Copenhagen, she received her Ph. D. from DTU in 1997.  Anja is cofounder of the companies Cantion, Silmeco and BluSense.  She has received numerous honors for her work, including the Villum Kann Rasmussen Award (2008), and the EliteForsk Award of the Danish Ministry of Research (2012).

Refreshments will be served in the NBIA Lounge after the colloquium.
