324Cu NCs2.5nmTEMThe as-prepared Cu NCs were approximately 2.5 nm in diameter
812Cu NCs1.70.1nmTEMThe TEM image of as-synthesized Cu NCs clearly shows the formation of spherical and well-dispersed particles with an average diameter of 1.7 ± 0.1 nm (Figure 2A).

324Facile Preparation of Homogeneous Copper Nanoclusters Exhibiting Excellent Tetraenzyme Mimetic Activities for Colorimetric Glutathione Sensing and Fluorimetric Ascorbic Acid Sensinghttps://doi.org/10.1021/acsami.0c11983MetalHerein, a facile and green method for preparing monodisperse, homogeneous copper nanoclusters (Cu NCs) with smaller size was developed, which used cysteine as the template and hydrazine hydrate as a reductant to reduce Cu2+.
