3863 677 Protoenzymes: The case of hyperbranched polymer-scaffolded ZnS nanocrystals https://doi.org/10.3390/life10080150 Sulfide Herein, we describe such possible protoenzymes: hyperbranched polymer-scaffolded metal-sulfide nanocrystals. Hyperbranched polyethyleneimine (HyPEI) and glycerol citrate polymer-supported ZnS nanocrystals (NCs) are formed in a simple process.

7894 677 HyPEI-supported ZnS NC 10 nm TEM The high-magnification FE (field-emission)-TEM micrograph in Figure 1a (inset) reveals spherical particles with an average size under 10 nm. The low-magnification TEM micrograph in Figure 1b shows the presence of both ~10 and ~50 nm aggregated particles in a solution of ZnS/HyPEI that was kept at room temperature for 14 days.
