The main purpose
1. Applied in the field of beauty and skin care
Nano-platinum can protect keratinocytes from ROS-induced apoptosis under ultraviolet irradiation. Rich anions can also neutralize a large number of free radicals and induce the absorption of nutrients. It is a new, efficient and luxurious raw material for skin care products. .
2. As sensor material
Nano-platinum has excellent catalytic performance, and can be used as an electrochemical sensor and a biosensor to detect glucose, hydrogen peroxide, formic acid and other substances.
3. As a catalyst
Nano-platinum is a catalyst that can improve the efficiency of some important chemical reactions and is widely used in fuel cells.
4. It can treat diseases related to oxidative stress
Nano-platinum is active in a wide range of pH and temperature. At extreme concentrations of H2O2, the efficiency of PtNP remains unchanged, which will inhibit natural HRP and CAT. The latest research results of PtNPs free radical quenching ability clearly show their great potential in nanomedicine, oxidative stress related disease scavengers, and their application prospects as artificial enzymes in nanodiagnosis.
① As an antioxidant: HSA-PtNP complex has high oxygen affinity and antioxidant activity, which opens up new prospects for the transport of oxygen in the blood. In addition, it also proved that PtNPs at 2-4nm and 2-amino-6-mercaptopurine, 3-amino-1,2,4-triazole-5-thiol and 2-mercapto-imidazole and other small molecule antioxidants have synergistic clearance It can be used to treat atherosclerosis and other vascular diseases.
②Treat rare diseases: Low concentration of PtNPs as a free radical scavenging material can completely restore the physiological balance of cells within 48h, providing a new way to treat rare diseases.
③ Antibacterial: The simulated enzyme activity of PtNPs can be used to induce high ATP secretion in cells, leading to bacterial growth inhibition, DNA damage and bacterial toxicity.
④Anti-tumor: The combined application of PtNPs in the treatment of hadron cancer increases the DNA damage caused by double-strand breaks in HT29 cancer cells.
⑤ For photothermal therapy: Trilobite platinum nanoparticles (TPN) have excellent photothermal properties, minimal cytotoxicity to normal cell lines, and kill cancer cells under the irradiation of near infrared light. These nanoparticles can effectively inhibit tumor growth and prevent osteolysis in bone metastasis models.
