Breakthrough in Nanotechnology: Researchers Develop Novel Approach to Solid Tumor Treatment

Strategic Insights -

Researchers at the Affiliated Hospital of Jiangsu University in China have made a significant breakthrough in the field of nanotechnology. A new study, published in the journal Nanoscale, presents a novel approach to solid tumor treatment using a photosensitive gel system that combines photothermal therapy with enzymatic degradation. This innovative system, dubbed NS/FPDA@DOX HA, has shown promise in effectively inhibiting tumor recurrence and metastasis.

Key Takeaways:

  • The NS/FPDA@DOX HA system is a photosensitive gel that utilizes enzyme-like properties to degrade the protective shell of fibrin surrounding tumor tissues, allowing for the precise release of antitumor drugs.
  • The system consists of folate-modified and doxorubicin-loaded polydopamine nanoparticles, which are combined with phenylboronic-grafted hyaluronic acid to load nattokinase.
  • Upon exposure to near-infrared light, the system converts light energy into heat energy, triggering tumor cell death and releasing tumor-associated antigens that can boost the body's antitumor immunity.
  • Nattokinase is gradually released by ROS/GSH/pH-triggered NS/FPDA@DOX HA degradation, which dissolves the protective shell of fibrin surrounding tumor tissues.
  • The released FA-P&PDA@DOX NAs utilize their surface folate molecules to specifically bind with folate receptors on the surface of tumor cells, enhancing their uptake by tumor cells.
  • The study concluded that the NS/FPDA@DOX HA system can effectively inhibit tumor recurrence and metastasis by promoting the infiltration of drug molecules and immune cells into solid tumor tissues.
