Herein, we report the unique—and first time—wavelength-dependent investigation with strictly monochromatic light of 305–405 nm wavelength into the stability of photoinitiator-derived chain termini of poly(methyl methacrylate) using a tunable la

A facile strategy to obtain nacre-mimetic nanocomposite materials is presented. The proposed economically feasible and environmentally friendly process consists in fusing dynamic poly(lipoic acid) and montmorillonite (MTM) via a water evaporation met

Macromolecules found in Nature display a precise control over the primary as well as higher ordered architectures. To mimic the folding found in Nature, we herein demonstrate the design and characterization of single-chain nanoparticles that are form

We introduce a powerful approach based on the combination of size exclusion chromatography with high-resolution mass spectrometry to selectively follow the compaction of discrete polymer chains that have uniform elemental composition. Single-chain na

We assess the versatility of high-resolution Orbitrap electrospray mass spectrometry (HR ESI MS) coupled to size exclusion chromatography (SEC) by challenging it with the to date most complex—for mass spectrometric analysis—single chain nanoparti
