The transientactivation of function using chemical fuels is common in nature, but much less in synthetic systems. Progress towards the development of systems with a complexity similar to that of natural ones requires chemical fuel selectivity. Here, we show that a self‐assembled nanosystem, composed of monolayer‐protected gold nanoparticles and a fluorogenic peptide, is activated for transient signal

neighboring units using conventional covalent linkages and molecular assembly methods to optimize these kinetic processes is quite difficult because of the complicated synthesis and random orientations. In this study, we propose a novel supramolecular strategy utilizing mixed self-assembled monolayers (SAMs) with two different chain lengths. Specifically, mixed Tc-SAMs on gold nanoclusters, which are
A systematic study has been reported to compare the pros and cons of both micellar and surfactant immobilized as self-assembled monolayer (SAM) on a nanoparticle system towards protontransfercatalysis. We showed the superiority of SAM compared to micelle at much lower concentration of headgroup compared to similar concentration of surfactants of even higher hydrophobicity.
据报道,一项系统研究比较了作为自组装单层 (SAM) 固定在纳米颗粒系统上的胶束和表面活性剂在质子转移催化方面的优缺点。我们展示了 SAM 与胶束相比的优越性,与相似浓度的疏水性更高的表面活性剂相比,头基浓度低得多。
