Problems solved by technology

As a reagent for cancer diagnosis and treatment, photothermal nanomaterials often need to be dispersed in water or biomass solutions, and the heat generated is only limited to the solution. On the other hand, as a medium, water has a high thermal conductivity, making The temperature that photothermal nanomaterials can reach in solution is limited and the temperature rise rate is slow. These two points make it difficult for photothermal nanomaterials to be applied in other fields, and they have become the most important factors that limit the application of photothermal nanomaterials.
