Porphyrins coordinated with platinum(II) chemotherapeutic drugs are attractive for the development of photosensitizers for photodynamic therapy (PDT) of cancer. In this paper, inorganic and metal-organic nanocomposites were synthesized with cascade-responsive imaging and photochemical synergistic effects. After endo/lysosomal escape, the outer metal-organic frameworks were degraded, leading to the release of an excellent photosensitizer (tetrapyridylporphyrin, PtTPyP). Subsequently, doxorubicin (DOX), inserted in the adenosine triphosphate (ATP) aptamer-functionalized gold nanoparticles, was released under the stimulation of endogenous ATP, synergistically enhancing cancer treatment. Fluorescence imaging allowed tracking of PtTPyP and DOX for real-time detection and on-demand therapy. This strategy endowed the nanocomposites with stability, responsiveness, effectiveness, and ease of synthesis, namely, sTREE strategy. Accordingly, our demonstration provided a promising and smart nanocarrier for imaging and drug delivery.

Inorganic derivatives of ammonia by substitution of one or more hydrogen atoms with chlorine atoms or organic compounds with the general formulas R2NCl and RNCl2 (where R is an organic group).
Compounds derived from organic or inorganic acids in which at least one hydroxyl group is replaced by an –O-alkyl or other organic group. They can be represented by the structure formula RCOOR’ and are usually formed by the reaction between an acid and an alcohol with elimination of water.
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.
Organic compounds that contain technetium as an integral part of the molecule. These compounds are often used as radionuclide imaging agents.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
