Traditional hot injection methods for the preparation of cesium lead halide perovskite nanocrystals (CsPbX PNCs, where X=Cl, Br, or I) rely on small molecule surfactants to produce PNCs with cube, plate, or rod-like morphologies. Here, we describe a new method whereby zwitterionic block copolymers are employed as macromolecular ligands in PNC synthesis, affording PNCs with excellent colloidal stability, high photoluminescence quantum yield, and in some cases distinctly non-cubic shapes. The block copolymers used in this study - composed of a poly(n-butyl methacrylate) hydrophobic block and zwitterionic methacrylate hydrophilic blocks - dissolve in useful solvents for PNC growth despite containing large mole percentages of zwitterionic groups.

- Heparin combined with GP IIb/IIIa inhibitors is effective for acute coronary syndrome (ACS) patients undergoing PCI, but bivalirudin has emerged as a strong alternative.
- In a study of 891 PCI patients with ACS, those on bivalirudin experienced better angiographic outcomes compared to those on heparin, despite fewer using adjunctive inhibitors.
- No significant differences in bleeding events or major adverse cardiac events were noted between the two groups, suggesting that bivalirudin could be as effective and safe as heparin in this high-risk setting.
