Medical researchers think specially tailored RNA sequences could turn off genes in patients' cells to encourage wound healing or to kill tumor cells. Now researchers have developed a nanocoating for bandages that could deliver these fragile gene-silencing RNAs right where they're needed (ACS Nano 2013, DOI: 10.1021/nn401011n). The team hopes to produce a bandage that shuts down genes standing in the way of healing in chronic wounds.
