Abstract
Photothermal therapy refers to the addition of targeted drugs with photothermal effects into the patient's body. Through targeting, the drug specifically recognizes tumor cells and accumulates around tumor cells. Afterwards, it is irradiated with a laser of a specific wavelength to achieve a local temperature increase, thereby achieving the effect of killing or locating tumor cells. Therefore, the most important part of this treatment method is the photothermal probe with a targeting effect and good photothermal effect. The existing photothermal probes are mainly composed of inorganic substances, organic small molecules and organic biomolecules. This paper will mainly introduce the development status and prospects of performance of these three types of photothermal probes to introduce photothermal agent development.

Summary
A tumor refers to the growth of cells formed by local cell proliferation under the action of various tumor-causing factors. Research on tumor treatment has been a popular direction of medical research in recent years, and many tumor treatment methods have been drawn and developed, including chemotherapy, radiotherapy, and surgical treatment. Surgical treatment has a high recurrence rate, and other methods are needed to help locate cancer cells. The development direction of modern cancer treatment is mainly to reduce the recurrence rate, reduce side effects, and accurately locate cancer cells. The second is organic molecules, but this method has disadvantages such as difficulty in accumulation at the tumor site and a relatively poor photothermal effect. This method has the advantages of good biocompatibility, good targeting effect and photothermal effect, and is currently a hot development direction. This paper will mainly analyze the properties, advantages and disadvantages and development status of these three types of photothermal agents
