Dr Swaminathan Iyer
Polymer brushes (or tethered polymers), first attracted attention in the
1950s when it was found that grafting polymer molecules to colloidal
particles was a very effectiver way to prevent flocculation.  The
repulsive force between brushes arises ultimately from the high osmotic
pressure inside the brushes.  Subsequently it was found that polymer
brushes could be useful in other applications such as new adhesive
materials, protein-resistant biosurfaces, surfactants, responsive
biointerfaces, controlled drug-delivery/release systems and thin film
sensors.  In this talk I will introduce the fundamentals of
macromolecules tethered to surfaces in the brush regime and the
thermodynamic/kinetic constraints associated with grafting polymers.
Following this, I will propose the use of poly (glycidy methacrylate)
(PGMA) as an anchoring platform to overcome some of the aforementioned
limitations.  Finally, I will talk about some of the recent
developments/applications using this anchoring platform in colloidal
state for drug delivery and multimodal imaging.
