SYNTHESIS The physical and chemical properties of nanomaterials are different to those of the corresponding bulk material. To make use of this feature, arranging atoms using chemical and biochemical processes to form nanomaterials like particles, rods, wires, tubes, can be performed applying a multitude of synthesis methods.

TB Nano-drug Delivery

TB is the leading cause of death in SA:

• Nano-based drug delivery system capable of slowly releasing the drug in a controlled and sustained manner

• Reduce dose frequency from daily to once a week

• Reduce treatment time

• Treat MDR and XDR-TB

• To address other diseases which fall under non-compliance

• Develop human capacity and infrastructure

• Successfully encapsulated 4 of the leading anti-TB drugs using double emulsion solvent evaporation - spray drying technique
