“…Biomimetic mineralization method refers to the controlled synthesis of biomimetic nanomaterials by regulating the reaction kinetics of an inorganic nucleation–crystallization process through the template effect of biological macromolecules based on the principle of biomineralization, thereby preparing nanozymes with biological performance. − According to various interactions between organisms and mineral materials, biomimetic mineralization can be categorized into in situ mineralization and mineral self-assembly. In a supersaturated state, biological macromolecules have a tendency to undergo in situ mineralization by forming electrostatic interactions with inorganic metal ions.…”

Cancer, as one of the leading causes of death worldwide, drives the advancement of cutting-edge technologies for cancer treatment. Transition-metal-based nanozymes emerge as promising therapeutic nanodrugs that provide a reference for cancer therapy. In this review, we present recent breakthrough nanozymes for cancer treatment. First, we comprehensively outline the preparation strategies involved in creating transition-metal-based nanozymes, including hydrothermal method, solvothermal method, chemical reduction method, biomimetic mineralization method, and sol−gel method. Subsequently, we elucidate the catalytic mechanisms (catalase (CAT)-like activities), peroxidase (POD)-like activities), oxidase (OXD)-like activities) and superoxide dismutase (SOD)-like activities) of transition-metal-based nanozymes along with their activity regulation strategies such as morphology control, size manipulation, modulation, composition adjustment and surface modification under environmental stimulation. Furthermore, we elaborate on the diverse applications of transition-metal-based nanozymes in anticancer therapies encompassing radiotherapy (RT), chemodynamic therapy (CDT), photodynamic therapy (PDT), photothermal therapy (PTT), sonodynamic therapy (SDT), immunotherapy, and synergistic therapy. Finally, the challenges faced by transition-metal-based nanozymes are discussed alongside future research directions. The purpose of this review is to offer scientific guidance that will enhance the clinical applications of nanozymes based on transition metals.

“…Zinc gallate (ZnGa 2 O 4 ), a ternary spinel material with a band gap of 4.4–4.7 eV, has exhibited excellent potential in future display system due to its prominent blue emission, high chemical and thermal stability, and good cathodoluminescence characteristics at low-voltage 4 , 5 . Compared with other luminescent materials, zinc gallate can be self-excited by Ga-O group, and has blue light emission 6 , 7 . ZnGa 2 O 4 can also be used as the matrix of fluorescent materials, which has high luminous efficiency and narrow spectral band.…”

Gallate material, a luminescent matrix with excellent performance is normally prepared by vapor deposition or solid phase sintering method at high temperature. However, it has not been solved to prepare gallate-based fluorescent materials with full-color luminescent properties at low temperature. In this paper, ZnGa2O4 undoped or doped with Cr or Mn nanoflowers composed of nanosheet-level structure were prepared by hydrothermal method at low temperature. Under ultraviolet light irradiation, ZnGa2O4, ZnGa2O4:Mn2+ and ZnGa2O4:Cr3+ display three primary colors of blue, green and red luminescence through self-excitation, Mn2+ and Cr3+ excitation respectively. The solid fluorescence yields of blue, green, and red colors are 32.3, 36.5, and 40.7%, respectively. It is highly expected to be applied to color display, biological imaging, white light devices.
