Copper sulfide nanoparticles have high application value in nanophotothermal therapy. In the future, the industry needs to continue to optimize the production process

Copper sulfide nanoparticles, referred to as CuS NPs and Cu2-xS nanoparticles, are an important P-type semiconductor material. Copper sulfide nanoparticles have excellent optoelectronic properties, capacitive properties, photothermal effect, thermal stability, conductive properties, catalytic properties, environmental protection properties, etc., and are widely used in optics, electronics, chemical industry, thermocouples, new energy, superconductors, environmental engineering, biomedicine There are broad market prospects in other fields, and it has become one of the popular materials studied in various countries.

Among them, biomedicine is the most promising application field for copper sulfide nanoparticles. Copper sulfide nanoparticles have a strong local plasmon resonance effect on near-infrared light (NIR) and can achieve high photothermal conversion efficiency under NIR excitation; at the same time, they also have good near-infrared light-induced photodynamic properties and can be used in NIR Under stimulation, high concentrations of reactive oxygen species are produced to kill tumor cells. Therefore, copper sulfide nanoparticles can be used as excellent photothermal conversion agents in the field of nanophotothermal therapy, including photothermal therapy (PTT), photodynamic therapy (PDT), etc. In the future, as the number of global cancer patients continues to increase and the market penetration rate of nanophotothermal therapy continues to increase, the market demand for copper sulfide nanoparticles will continue to rise, and the industry development prospects are promising.

According to the “China Copper Sulfide Nanoparticle Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that there are various production methods for copper sulfide nanoparticles, mainly including hydrothermal synthesis method, module method, microwave radiation method, sonochemical method, liquid phase precipitation method, etc. Among them, the hydrothermal synthesis method is currently the mainstream method for producing copper sulfide nanoparticles. It refers to a method that uses copper sulfate, thiourea, etc. as raw materials and citric acid as a surfactant to produce copper sulfide nanoparticles through a chemical reaction.

Most of the current production methods for copper sulfide nanoparticles have shortcomings such as long reaction times, high temperature and pressure, and high requirements for reaction equipment. It is basically difficult to achieve industrial mass production. Therefore, in the future, the industry will need to find new ways to produce copper sulfide nanoparticles to promote the continued acceleration of industrialization.

The technical barriers to copper sulfide nanoparticles are relatively high. The industry is still in its early development stage, and there are only a few domestic companies such as Jiangsu Xianfeng Nano, Xi’an Qiyue Biotechnology, and Nanjing Jike Biotechnology. However, there are still many domestic research institutions and companies that are increasing their research and development efforts on copper sulfide nanoparticles, such as Shandong University, Shanghai University of Technology, Wuhan University of Technology, Hefei Institute of Physical Sciences, Chinese Academy of Sciences, etc. The industry has huge potential for future development.

Industry analysts said that copper sulfide nanoparticles are a type of advanced high-performance materials that are widely used in optics, new energy, superconductors, and biomedicine. It has broad application prospects in other fields. However, due to technical limitations, the domestic copper sulfide nanoparticle industry is still in its early stages of development, with a small number of companies and low production technology levels. In the future, local companies will need to continue to innovate production processes and products to accelerate the development of the industry.
