CuS nanoparticles (CuS NPs) have excellent photothermal conversion effects due to their strong and wide-band light absorption. The composite of CuS NPs may enhance the light absorption and photoheating effect, and their broad applications have appealed to wide interests. In this paper, ethylene imine polymer (PEI)-linked graphene quantum dots (PEI_GQDs) were easily obtained by an ultrasonic-assisted hydrothermal approach, and CuS nanoshells (NSs) were prepared with Cu 2 O NSs as a template. The composite of CuS@PEI_GQDs NSs was easily obtained by selfassembly due to the electrostatic attraction between PEI_GQDs and CuS NSs. The morphology, structure, surface chemistry, and optical absorption of the prepared nanomaterials were characterized by multimicroscopic techniques. The results of high-resolution transmission electron microscope (HRTEM), X-ray diffractometer (XRD), Fourier transform infrared (FTIR), X-ray photoelectronic spectroscopy (XPS), and energy-dispersive spectrum (EDS) show that the PEI_GQDs were successfully linked on the surfaces of the CuS NSs; the FTIR analysis reveals that there is an interaction between CuS NSs and PEI_GQDs by chelation between Cu 2+ and −NH 2 in PEI_GQDs. The pore size distribution indicated that both the CuS NSs and CuS@PEI_GQDs NSs contained mesopores in the wall shells. The CuS@PEI_GQDs NSs displayed enhanced absorption within 190−500 and 630−1100 nm compared to the CuS NSs. The photoheating effects of CuS@PEI_GQDs NSs and CuS NSs were investigated under 808 nm laser and sunlight irradiation, and CuS@PEI_GQDs NSs presented a better photoheating effect and photothermal stability than CuS NSs. Our results provide a facile approach to fabricate other GQD-coated nanomaterials. The excellent photoheating effects of CuS@ PEI_GQDs NSs are promising in photothermal conversion.

“…Further, Farzin and coworkers (2018) synthesized a highly ordered 3D flower-like hierarchical CuS hollow nanosphere@N-S-rGO bionanocomposite for glucose detection. This material provided a remarkable enhancement (~40-fold) in the glucose detection limit that was attributed to rapid electron transfer on the surface of the 3D CuS NSs@N-S-rGO and the synergistic interaction of 3D CuS NSs and N-S-rGO [31]. Moreover, a colorimetric ascorbic acid sensor was developed based on a synergistic catalytic strategy using 5,10,15,20tetra (4-pyridyl) À21H, 23H-porphyrin functionalized CuS nanohexahedrons that enhanced peroxidase-like activity [32].…”

“…The discovery of the first nanozyme, Fe 3 O 4 nanoparticle (NP), has aroused extensive research interest in recent years. Many nanoscale materials with peroxidase-like performance had been studied successively, including metal-oxide nanoparticles, noble metal nanomaterials, sulfide nanomaterials, and polymetallic nanomaterials. − Especially, nickel disulfide (NiS 2 ), a kind of p-type semiconductor was widely used in solar cells, photocatalysis, electrochemistry, lithium-ion batteries, and biosensors. In our early work, NiS 2 nanoparticles were demonstrated to possess a peroxidase-like activity, but their catalytic activity was unsatisfactory.…”

Exploring peroxidase-like nanozymes with high catalytic activity is an urgent task to construct a fast, convenient, and selective colorimetric sensing platform. In this work, a nanozyme, 5,10,15,20-tetrakis(4-carboxyl phenyl)porphyrin-functionalized NiS 2 nanoparticles, anchored on the surface of graphene (Por-NiS 2 /GO) was designed. Compared with NiS 2 nanoparticles anchored on the surface of graphene (NiS 2 /GO), Por-NiS 2 /GO had a higher peroxidase-like activity due to the introduction of porphyrin. The size of NiS 2 nanoparticles was about 110−250 nm. The peroxidase-like behaviors of Por-NiS 2 /GO were evaluated using the chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) with a fast-blue color change in less than 1 min. Electron spin resonance (ESR) data revealed that the excellent performance of Por-NiS 2 / GO was due to the active oxygen species produced, including hydroxyl radical ( • OH) and superoxide radical ( • O 2 − ), during the catalytic reaction, owing to the synergetic effect among different components including porphyrin, NiS 2 , and GO. Thus, based on the enhanced peroxidase-like activity of Por-NiS 2 /GO, a fast, sensitive, and selective colorimetric sensing platform of H 2 O 2 has been constructed, and furthermore, a sensing platform for cholesterol was also developed coupled with cholesterol oxidase (ChOx). The colorimetric sensing platform was validated by detecting cholesterol in serum samples.
