My research is focused on the biomedical applications of multifunctional inorganic nanomaterials in the field of tumor diagnosis and therapy, including (1) dynamic therapy of deep-seated tumor stimulated by X-ray or ultrasound, (2) multifunctional nanomaterials synthesized by living cells for comprehensive cancer therapy. More than 20 papers have been published in the top journal of nanomedicine such as Nano Letters, Advanced Functional Materials, Advanced Science, Small etc.
