Abstract:
Covalent organic frameworks (COFs) have attracted great attention across diverse research fields. However, only a few reports about the biomedical application of COFs are found in the literature. Attributed to the highly porous and tunable structure, as well as good thermal stability, COFs show great potential as drug carriers for chemotherapy. In this work, doxorubicin (DOX) was successfully in situ loaded into a COF by a one-pot method for the first time. The resultant DOX@COF platform exhibited high drug-loading capacity (32.1 wt %) and pH-responsive release property. In vitro and in vivo experiments demonstrated its good biocompatibility and enhanced antitumor efficacy.

Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...

To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
