A Novel Way of Targeting TB using Aptamers and Nanotechnology

To optimize the effectiveness of current anti-tuberculosis drugs, Boitumelo Semete of the CSIR in South Africa will work with collaborators to develop "sticky nanoparticles" that specifically attach to TB-infected cells. Once taken in by these cells, the nanoparticles will slowly degrade, releasing the anti-TB drugs and killing the bacteria. With this novel drug delivery system, the team aims to improve the bioavailability of the current therapies, with the possibility of shortening the treatment period for TB as well as reduce drug side effects.
