Seminar - Applications of functionlised nanomaterials

Seminar at the School of Chemistry, University of the Witwatersrand

Seminar: Wednesday, 29th April 2009
Time: 11:15 am, Room C6 Humphrey Raikes Building (Also known as the Chemistry Building)
Speaker: Dr Rui Krause from the UJ
Title: "Applications of functionlised nanomaterials"

Abstract:
Over the past five years the nanomaterials group at UJ and the water treatment group have collaborated to use carbon nanomaterials and nano-structured polymers for various water-treatment applications. These nanoporous polymers, based on cyclodextrins and calixarenes, have been applied to the removal of organic pollutants and some heavy-metal contaminants in both drinking-water and industrial applications. The flexibility of the polymer-nanomaterial composites has allowed us to support metal catalysts for antibacterial action, or photocatalytic enhancement.

Recently we have started to examine doped nanomaterials and functionalised nanomaterials as chemo-sensors for specific pollutants, providing polymers that can be used for both the detection and removal of a broad range of pollutants.

These functionalised nanomaterials have recently also attracted some interest in medicinal applications such as directed drug-delivery, and in biotechnology applications.

Personalised Medicine: An Opportunity for Investment

The pharmaceutical industry is currently facing some key challenges. The increase in drug development costs, a decrease in the number of drugs being approved, and scrutiny from regulatory authorities are forcing companies to look at alternative revenue generators. Patients themselves are also demanding more effective and safer drugs.
