Latest Patents
One of his latest patents is titled "Ultrathin calcinated films on a gold surface for highly effective laser desorption/ionization of biomolecules." This invention involves a nanoscale calcinated silicate film that is fabricated on a gold substrate. It is designed for matrix-free laser desorption ionization mass spectrometry (LDI-MS) analysis of biomolecules. The film is prepared using a layer-by-layer deposition and calcination process, allowing for precise control over the thickness and surface properties. This innovation exhibits outstanding efficiency in LDI-MS, with extremely low background noise, enabling effective analysis of low mass weight samples and detection of large biomolecules such as amino acids, peptides, and proteins. The film's advantages include ease of preparation, high reproducibility, low cost, and excellent reusability. Experimental parameters influencing LDI performance have been systematically investigated, revealing that the presence of citric acid significantly enhances performance by facilitating protonation of the analyte and reducing fragmentation.
Another significant patent by Quan Cheng is related to "Color and shape changing polymeric ribbons and sheets." This invention provides the design, synthesis, and characterization of compositions comprising asymmetric bolaamphiphilic lipids. These lipids form extended polymeric ribbons and wide sheets, which can be doped with various compounds to fine-tune their fluidity and rigidity. Upon an increase in pH, these compositions undergo calorimetric and morphological transformations.
