Accurate targeting and low side effects are crucial for tumor theranostics. Herein, an in situ targeted therapy strategy which relies on a photothermally triggered theranostics nanoplatform is proposed. Taking advantage of spherical nucleic acids, black phosphorus nanosheets and zinc porphyrin metal‐organic framework (PPF‐1) nanosheets are programmed by DNA hybridization to result in a “sandwich”...
In article number 1902755, Xuemei Wang, Hui Jiang, and co‐workers demonstrate the aggregation of slight‐hollow gold silver nanocages by glutathione for both enhancement of photoacoustic signals at tumor sites and near infrared photothermal therapy. This work offers a new multifunctional strategy for efficient tumor theranostics.
Gold–silver nanocages (GSNCs) are widely used in cancer imaging and therapy due to excellent biocompatibility, internal hollow structures, and tunable optical properties. However, their possible responses toward the tumor microenvironment are still not well understood. In this study, it is demonstrated that a kind of relatively small sized (35 nm) and partially hollow GSNCs (absorbance centered at...
Functionalized hydrogels have aroused general interest due to their versatile applications in biomaterial fields. This work reports a hydrogel network composed of gold nanoclusters linked with bivalent cations such as Ca2+, Mg2+, and Zn2+. The hydrogel exhibits both aggregation‐induced emission (AIE) and aggregation‐induced electrochemiluminescence (AIECL) effects. Most noteworthy, the AIECL effect...
