摘要: Abstract Development of multifunctional theranostic nanoplatforms for diagnosis and therapy of cancer still remains a great challenge. In this work, we report the use of hyaluronic acid-modified Fe 3 O 4@ Au core/shell nanostars (Fe 3 O 4@ Au-HA NSs) for tri-mode magnetic resonance (MR), computed tomography (CT), and thermal imaging and photothermal therapy of tumors. In our approach, hydrothermally synthesized Fe 3 O 4@ Ag nanoparticles (NPs) were used as seeds to form Fe 3 O 4@ Au NSs in the growth solution. Further …
