In the field of regenerative medicine, such as artificial organs, nerve repair, etc. Or develop corresponding inhibitors (such as enzyme inhibitors) for functional domains based on protein structure analysis data. Using microarray nucleic acid chip or protein chip to find pathogenic genes. Or use antibody technology to send toxins into cancer cells with special markers. Or use gene cloning technology for gene therapy. Gene therapy uses molecular biological methods to introduce the target gene into the patient's body to express the target gene product, so as to treat the disease. It is a new technology born by the combination of modern medicine and molecular biology. Gene therapy, as a new way to treat new diseases, has brought light to the radical cure of some refractory diseases.
