SEMINAR CANCELLED - 'Optically Induced Interactions in Nanocontainers and Nanostructured Surface' with Professor Helmuth Moehwald
Date: 2 March 2018 Time: 16:00 - 17:00
OUR APOLOGIES - THIS SEMINAR WAS CANCELLED DUE TO UNFORESEEN CIRCUMSTANCES - WE HOPE TO RESCHEDULE THE SEMINAR LATER IN THE YEAR
The Layer-by-Layer technique of forming ultrathin films with high precision and from different polymers and particles could be converted to coat sacrificial colloidal particles and thus hollow capsules. These are suitable for drug delivery, and for this the material has to be varied from synthetic polymers to biopolymers and peptides. As the capsule shells can be made environmentally sensitive and opened on demand, they can be used for targeted drug delivery, for cell biological studies of immune response and also as self-repairing coatings.
Treating a surface by ultrasound can make it mesoporous, and these pores can again serve as drug containers. Coating them with sensitive organic films can again enable triggered release. In case of a titania support the light induced charge separation in the support can lead to a local pH change, which in turn can cause either triggered release or change the elasticity of the coating. This can be made use of in controlling the growth of adherent cells with perspectives in stem cell reasearch and in actuators in microfluidic devices.
