Ultrasmall black phosphorus nanosheets (BPs) can trigger systemic inflammations. In their Communication (DOI: 10.1002/anie.201706228) X.-F. Yu, G. Jiang et al. report a method to reduce this side effect by surface modification of bare BPs with titanium sulfate (TiL4@BPs). The girl represents a potential candidate exposed to bare BPs through various routes during a wide application of this material. The effect of the bare BPs is shown by red shading. The BPs are less harmful after conversion to TiL4@BPs.
