  • Organic solvent method for preparing membrane protein based nanosheets and membranes based on nanosheets
    Patent number: 12220667
    Abstract: The present disclosure describes compositions and methods for preparing membrane protein nanosheets and two-dimensional crystals. In particular, the methods employ a solvent. A mixture of a polymer and a membrane protein is solubilized in the solvent, applied to a substrate, and subsequently dried to form the nanosheet or two-dimensional crystal. Applicants have surprisingly found that the membrane proteins maintain their structure when exposed to solvents during the short processing time utilized.
    Type: Grant
    Filed: December 21, 2021
    Date of Patent: February 11, 2025
    Assignee: THE PENN STATE RESEARCH FOUNDATION
    Inventors: Manish Kumar, Tingwei Ren, Woochul Song, Yu-Ming Tu
  • Method for biological or biomimetic channel-based membrane fabrications using layer-by-layer structure
    Patent number: 11745146
    Abstract: The present disclosure describes membrane compositions and methods for preparing membrane compositions. In particular, the methods employ a layer-by-layer approach to membrane preparation. The membrane compositions provide significantly enhanced membrane performance over existing commercial membranes, particularly in terms of permeability and selectivity.
