Organic Polymer Composites for Enhanced Intracellular Uptake and Bioimaging

What is it about?

Polymer-modified metal–organic frameworks combine the advantages of both soft polymers and crystalline metal–organic frameworks (MOFs). It is a big challenge to develop simple methods for surface modification of MOFs. In this work, MOF@microporous organic polymer (MOP) hybrid nanoparticles (UNP) have been synthesized by epitaxial growth of luminescent boron-dipyrromethene (BODIPYs)–imine MOPs on the surface of UiO-MOF seeds, which exhibit low cytotoxicity, smaller size distribution, wellretained pore integrity, and available functional sites. After folic acid grafting, the enhanced intracellular uptake and bioimaging was validated.
