Gold nanoparticle-based supraspheres, which are analogues of supramolecular cages and containers, can be used to perform classical host-guest chemistry, according to new experiments by researchers in Israel and Switzerland. Although real-world applications may be a way off, at the laboratory level these materials may be used as soluble systems for better understanding phenomena associated with the uptake of substrates by porous solid-state materials. Areas such as catalysis, sensing, environmental clean-ups (at small scales and selectively for specific targets) and medicine (drug or diagnostic cargo delivery) might also benefit……
