  • Patent number: 11883535
    Abstract: Liposomes termed as small unilamellar vesicles (SUVs), can be synthesized in the 20-50 nm size range, but encounter challenges such as instability and aggregation leading to inter-particle fusion. This limits their use as a therapeutic delivery agent. Increasing the surface negative charge of SUVs, via the attachment of anionic entities such as DNA/RNA, increases the colloidal stability of these vesicles. Additionally, the dense spherical arrangement and radial orientation of nucleic acids exhibits unique chemical and biological properties, unlike their linear counterparts. These liposomal particles, are non-toxic and though anionic, can efficiently enter cells without the aid of ancillary cationic transfection agents in a non-immunogenic fashion. These exceptional properties allow their use as delivery agents for gene regulation in different therapies and offer an alternative platform to metal core spherical nucleic acids.

  • Patent number: 11479642
    Abstract: A method of producing a polyether polyol that includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, the low molecular weight initiator having a number average molecular weight of less than 1,000 g/mol and a nominal hydroxyl functionality at least 2, the one or more monomers including at least one selected from propylene oxide and butylene oxide, and the polymerization catalyst being a Lewis acid catalyst having the general formula M(R1)1(R2)1(R3)1(R4)0 or 1. Whereas, M is boron, aluminum, indium, bismuth or erbium, R1, R2, and R3 each includes a same fluoroalkyl-substituted phenyl group, and optional R4 includes a functional group or functional polymer group. The method further includes forming a polyether polyol having a number average molecular weight of greater than the number average molecular weight of the low molecular weight initiator in the presence of the Lewis acid catalyst.

  • Publication number: 20220283089
    Abstract: Methods of imaging a 2D sheet are provided. In embodiments, such a method comprises illuminating a sample with light having a wavelength 1, the sample comprising a quenching substrate; a transparent, non-quenching 2D sheet on the quenching substrate; and a fluorescent layer comprising fluorescent dye molecules on the transparent, non-quenching 2D sheet and the quenching substrate, providing background domains and 2D sheet domains in the sample, wherein the light induces fluorescence of the dye molecules in the fluorescent layer. The method further comprises detecting fluorescence from the sample to provide an image of the transparent, non-quenching 2D sheet, wherein an intensity IB of the detected fluorescence from the background domains is less than an intensity I2DSs of the detected fluorescence from the 2D sheet domains, thereby providing contrast in the image.
