Latest Patents

Shixiang Cheng's latest patents include two groundbreaking inventions. The first is a Method for preparing PEI-lipid nanoparticles used for delivering an mRNA vaccine and transfecting stem cells. In this method, Cheng outlines a multi-step process that begins with the addition of anhydride to a polyethyleneimine (PEI) solution, leading to the formation of polycarboxylic acid. Following that, he combines PEI-LNPs with various lipids in a chloroform solution which undergoes vacuum evaporation. This innovative process enables the formation of a stable complex with mRNA, thereby facilitating efficient delivery of nanovaccines.

The second patent is a Method for non-enzymatic 3D culture and amplification of mesenchymal stem cells. This patent presents an efficient approach by using PLGA porous microspheres and a thermosensitive PLGA-PEG-PLGA coating. The method allows for the non-enzymatic separation of stem cells, maximizing amplification without additional enzymatic processes. Both inventions demonstrate Cheng's commitment to pushing the boundaries of scientific research and its practical applications.
