Problem addressed

Over the past decades, there has been emerging interest in using active proteins for various biological applications, such as cancer therapy, gene editing, and vaccination. However, development on cytosolic protein delivery focusing on intracellular targets is still challenging, mainly due to their large molecular weights, low cellular affinity, and poor endosomal escape ability.

  • The nanocarrier can protect the cargo protein during blood circulation.
  • The photoresponsive moiety inside the nanocarrier can offer an on-demond drug delivery.
Key impact
  • Significantly enhanced intracellular protein delivery paves the way for the application of therapeutic proteins functioning intracellularly
  • Phototriggered drug release offers a targeting treatment
  • Simple preparation process results in low cost
  • Intracellular delivery of therapeutic proteins
  • Gene editing
