  • Artificial cells can deliver molecules better than the real thing

    With an onion-like structure, the artificial cells developed by researchers at Penn appear more stable and better equipped to carry cargo than their natural and commercial counterparts.
    Far left is chemical with phenol rings and long carbon chains, underneath are red circles showing the onion-like structure. Center panel shows a protein structure with a fluorescent tag marked by a green star, labeled with benzyl-guanine, SNAP protein, DNA Aptamer, FAM dye, His-tag, NI2+, and RH-NTA. Last figure shows the same protein in the center replicated many times to form a circular structure.
