An arginyl‐glycyl‐aspartic acid peptide‐modified carboline ruthenium complex KS‐Ru self‐assembled in a pH‐sensitive manner. It entered the lysosomes and formed nanoflowers, leading to lysosomal swelling. In addition, it entered the nucleus to damage DNA, inducing immunogenic cell death. Thus, it realized a dual impact on tumor growth and metastasis through synergistic chemotherapy and immunogenic...
Several DNA‐damaging antitumor agents, including ruthenium complexes, induce immunogenic cell death (ICD). In this study, an arginyl‐glycyl‐aspartic acid (RGD) peptide‐modified carboline ruthenium complex (KS‐Ru) is synthesized as a chemotherapeutic nanodrug and an ICD inducer. The RGD peptide, an integrin ligand, provides tumor‐specific targeting and promotes self‐assembly of the KS‐Ru complex. The...
Functional metamaterials can be constructed by assembling nanoparticles (NPs) into well‐ordered structures, which show fascinating properties at different length scales. Using polymer‐grafted NPs (PGNPs) as a building block, flexible composite metamaterials can be obtained, of which the structure is significantly affected by the property of polymer ligands. Here, it is demonstrated that the crystallization...
Nanoparticles form long‐range micropatterns via self‐assembly or directed self‐assembly with superior mechanical, electrical, optical, magnetic, chemical, and other functional properties for broad applications, such as structural supports, thermal exchangers, optoelectronics, microelectronics, and robotics.
