“…1,[9][10][11][12][13] Various methods have been applied to fabricate copper selenide nanostructures with controllable morphologies and sizes. 1,9,11,[14][15][16][17][18][19][20][21] So far, well-aligned copper selenide films on Cu substrates containing 2D nanosheets or 3D microstructures assembled by nanosheets have been prepared via hydrothermal/solvothermal methods 1,9 and a microwave-assisted non-aqueous approach, 11 where heating is invariably required and organic solvents are often needed. This is not beneficial for the large scale industrial production of copper selenide nanomaterials from an economic point of view.…”

A tetragonal Cu 2 Se film containing a well-aligned nanosheet array with scattered 3D flower-like microstructures on top was synthesized for the first time by a rapid one-step low-energy route, which is beneficial for large scale industrial production due to savings in energy, time and expensive instruments. Phase transformation occurred after scraping the film from the Cu substrate, and heating or grinding the Cu 2 Se powder in air. The Cu 2 Se/Cu 3 Se 2 composite containing p-Cu 2 Se/p-Cu 3 Se 2 heterojunctions was obtained by simply calcining the Cu 2 Se in air at 300 °C for 3 h. The composite has enhanced gas sensing properties towards acetone gas and a lower band gap energy compared to Cu 2 Se.

Photothermal therapy has attracted much interest for use in cancer treatment in recent years. In this study, Cu Se nanoparticles as a novel photothermal agent modified by chitosan (CS-Cu SeNPs) were successfully synthesized through a facile route at room temperature. The as-synthesized CS-Cu SeNPs exhibited good water solubility and significant stability. CS-Cu SeNPs can efficiently convert near-infrared (NIR) light into heat and exhibit excellent thermostability. In vitro experiments showed that CS-Cu SeNPs had selective cellular uptake between cancer and normal cells and expressed clear anticancer activity on A375 and HeLa human cancer cells. In addition, the anticancer activity was increased to about 400 % by combination with a laser at 808 nm, which acted through induction of apoptosis with the involvement of intrinsic and extrinsic pathways. CS-Cu SeNPs irradiated with a laser effectively triggered the intracellular reactive oxygen species (ROS) overproduction that promoted cell apoptosis. Therefore, the developed CS-Cu SeNPs could be used as a novel phototherapeutic agent for the photothermal therapy of human cancers.
