Copper sulfide nanoparticles are extensively employed in the field of functional materials. However, synthesizing the desired nanoparticles in a controlled manner is challenging due to the variety of copper sulfide phases and their potential transformations. Here, we utilize a unified theoretical approach combining a high-throughput computational workflow, ab initio atomistic thermodynamics, and the Wulff theorem to study the thermodynamic stability of copper sulfide nanoparticles. Theoretical sizedependent phase diagrams are constructed for the first time, considering various sulfur chemical potentials. This study unveils the evolution of crystal morphology under varying external conditions and underlines the crucial role of surface energy in maintaining the stability of copper sulfide nanoparticles. Our findings offer a theoretical guide for experimental endeavors aimed at synthesizing the desired surface morphology and phases of copper sulfide nanomaterials.

Photothermal therapy is a promising approach to cancer treatment. The energy generated by the photothermal effect can effectively inhibit the growth of cancer cells without harming normal tissues, while the right amount of heat can also promote cell proliferation and accelerate tissue regeneration. Various nanomaterials have recently been used as photothermal agents (PTAs). The photothermal composite scaffolds can be obtained by introducing PTAs into bone tissue engineering (BTE) scaffolds, which produces a photothermal effect that can be used to ablate bone cancer with subsequent further use of the scaffold as a support to repair the bone defects created by ablation of osteosarcoma. Osteosarcoma is the most common among primary bone malignancies. However, a review of the efficacy of different types of photothermal composite scaffolds in osteosarcoma is lacking. This article first introduces the common PTAs, BTE materials, and preparation methods and then systematically summarizes the development of photothermal composite scaffolds. It would provide a useful reference for the combination of tumor therapy and tissue engineering in bone tumor-related diseases and complex diseases. It will also be valuable for advancing the clinical applications of photothermal composite scaffolds.

Copper‐based nanomaterials (Cu‐based NMs) with favorable biocompatibility and unique properties have attracted the attention of many biomedical researchers. Cu‐based NMs are one of the most widely studied materials in cancer treatment. In recent years, great progress has been made in the field of biomedicine, especially in the treatment and diagnosis of tumors. This review begins with the classification of Cu‐based NMs and the recent synthetic strategies of Cu‐based NMs. Then, according to the abundant and special properties of Cu‐based NMs, their application in biomedicine is summarized in detail. For biomedical imaging, such as photoacoustic imaging, positron emission tomography imaging, and multimodal imaging based on Cu‐based NMs are summarized, as well as strategies to improve the diagnostic effectiveness. Moreover, a series of unique structures and functions as well as the underlying property activity relationship of Cu‐based NMs were shown to highlight their promising therapeutic performance. Cu‐based NMs have been widely used in monotherapies, such as photothermal therapy (PTT) and chemodynamic therapy (CDT). Moreover, the sophisticated design in composition, structure, and surface fabrication of Cu‐based NMs can endow these NMs with more modalities in cancer diagnosis and therapy. To further improve the efficiency of cancer treatment, combined therapy based on Cu‐based NMs was introduced in detail. Finally, the challenges, critical factors, and future prospects for the clinical translation of Cu‐based NMs as multifunctional theranostic agents were also considered and discussed. The aim of this review is to provide a better understanding and key consideration for the rational design of this increasingly important new paradigm of Cu‐based NMs as theranostic agents.
