In situ nanochemical imaging of label-free drugs: a case study of antimalarials in Plasmodium falciparum-infected erythrocytes

Chem Commun (Camb). 2012 Jan 21;48(6):910-2. doi: 10.1039/c1cc16211j. Epub 2011 Dec 5.

Abstract

We report here for the first time the in vitro localization of unlabeled antimalarial drugs with high spatial resolution. This strategy further enhances our understanding of the action mechanisms of antimalarial drugs. Our approach may be applied to a wide range of domains where quantitative chemical imaging of drugs at the sub-cellular level appears critical.
