 This study proposes a novel approach to delivering combertastatin derivatives to tumor cells. By encapsulating these compounds within polymeric micelles, the authors were able to reduce the amount of drug that enters healthy cells, while increasing its uptake in tumor cells. Additionally, the micelles can be visualized using a flow cytometer, allowing researchers to quantify the number of cells that have taken up the drug. This article was authored by Igor D.
