Despite their promising applications, there are several challenges in using nanostars. One of the primary issues is the reproducibility of their synthesis. Achieving consistent size and shape is crucial for their reliable performance in applications. Another challenge is their stability; nanostars can be prone to aggregation, which can alter their properties. Additionally, the biocompatibility and potential toxicity of nanostars need to be thoroughly assessed, especially for biomedical applications. Addressing these challenges requires ongoing research and development in the field of nanotechnology.
