In the realm of pharmaceutical drug delivery and bioimaging, the innovative design of membrane transporters is crucial. This highlight article focuses on the recent collaborative study published in Advanced Materials (DOI: 10.1002/adma.202309219) between the research groups of Nau and Rompel, investigating Keggin and Anderson-Evans type polyoxometalates (POMs) as superchaotropic carriers in both model membranes and live cells under physiological conditions. The Kegginoidal POM carriers, at concentrations as low as 5 µM, successfully transport various oligo- and polypeptides, surpassing the performance of boron clusters (DOI: 10.1038/s41586-022-04413-w).
