  The capture of circulating tumor cells(CTCs)from blood is highly important but challenging in cancer diagnosis and therapy.Recently,hollow mesoporous silica nanoparticle(HMSN)has been acted as an apromising nanomaterials due to the characteristics of lower toxicity,controlling release,good cellular uptake,cell specific targeting,and the ability of carrying drug.
