Although nanofibrous meshes are considered promising cultivation beds for maintaining cell differentiation, 3D cultivation is not possible because their nanoporous structures impede cell infiltration. To facilitate transverse cell migration across nanofibrous meshes, electrospun nanofibers are prepared with structures that vary in response to red laser light. Polyoxalate (POX), composed of oxalate...
In article number 1802618, Joong‐jae Lee, Hak‐Sung Kim, and co‐workers develop an intracellular protein delivery system by sequence specific DNA‐protein interactions for targeted therapy. Engineered nucleoproteins are sequentially assembled onto the surface of gold nanoparticles. The resulting nucleoprotein nanoparticles exhibit highly programmable designability for functional protein loading, and...
With a growing number of intracellular drug targets and the high efficacy of protein therapeutics, the targeted delivery of active proteins with negligible toxicity is a challenging issue in the field of precision medicine. Herein, a programed assembly of nucleoprotein nanoparticles (NNPs) using DNA and zinc fingers (ZnFs) for targeted protein delivery is presented. Two types of ZnFs with different...
Gold nanoparticles (AuNPs) and matrix metalloproteinase (MMP)-2 cleavable peptides are clicked into gold nanoparticle clusters (AuNCs) for enhanced drug localization and micro computerized tomography (μCT) theranostic of tumors. AuNPs are co-functionalized with doxorubicin (DOX) and an azide-terminated polymer (DOX/N3@AuNPs), and the DOX/N3@AuNPs are associated into DOX@AuNCs in the presence of an...
