Gene delivery technology is widely used in cell therapy, nucleic acid-based vaccines, protein production, gene therapy, etc. We have developed a non-viral gene delivery technology-MPGene, which has excellent gene delivery efficiency (50-80) for human mesenchymal stem cells,also has the characteristics of low production costhigh safety. In the future, MPGene has the potential to be used in important biomedical fields such as gene delivery reagents, major trauma cell therapy, malignant tumor treatmentcartilage cell therapy.

Inorganic porous nanofibers with surfaceinterface defects are prepared through humidity-controlled electrospinninghigh-temperature annealing technology. Under the irradiation of light sources of different wavelengths (380~780 nm), the bound electrons stored in the valence band can be excited to the conduction band to form free electrons on the surface of the material, generating different intensities of microcurrents, light sensitivitymicrocurrent changes. Because the "inorganic nanofiber" technology has high uniquenesshigh product compatibility, it can be applied to a wide range of markets.
