Barcoded DNA structures for the subcellular profiling of proteins

This issue highlights tumour-cell-derived microparticles as efficient drug-delivery carriers, the boosting of chemotherapy in colonic tumours via the phage-guided modulation of gut microbiota, the delivery of a therapeutic monoclonal antibody to metastases in the central nervous system, the augmentation of canonical Wnt signalling to produce cell factories of therapeutically potent exosomes, integrated glass microelectrodes for in vivo brain electrophysiology, and barcoded DNA nanostructures for the profiling of subcellular protein distribution.

The cover illustrates tetrahedral DNA nanostructures that act as barcodes for the high-throughput multiplexed profiling of the subcellular expression and distribution of proteins in cells.
