  • Patent number: 10993960
    Abstract: A pharmaceutical composition includes polymer units ? and ?, each having a hydrophilic polymer chain bound to a cationic polymer chain, and a drug. The polymer units ? and ? are radially arranged such that the cationic polymer chains are directed inward and the hydrophilic polymer chains are directed outward, thereby forming a micelle with the drug encapsulated in the micelle. The cationic polymer chain of the polymer unit ? has a phenylboronic acid group in a side chain, and the cationic polymer chain of the polymer unit ? has a phenylboronic acid binding site in a side chain. The phenylboronic acid group and the phenylboronic acid binding site form a cross-linked structure that can dissociate in an acidic environment and/or in the presence of a substance capable of competitive binding.

  • Patent number: 10843148
    Abstract: A new simple transfection method using an integrated electrowetting nano-injector (“INENI”) with controlled dosage delivery and high transfection efficiency is disclosed. The volume of delivery can be controlled via voltage application to an inner and outer electrode integrated into a nano-pipette. With higher voltages, more liquid enters the INENI and with lower voltages liquid is expelled. This method can be used to deliver plasmid DNA directly into the nuclei of cells. The INENI requires only the use of a single probe since both electrodes are integrated into the same nano-pipette. Hence, more space is available, and ergo the INENI offers a simplistic means for direct injection of metered amounts of exogenous material into the confines of a cell cytoplasm and/or nucleus while retaining full cell viability.
