    Abstract: There is a solenoid including a stator having a first stator tooth and a second stator tooth, and an armature having a first armature tooth and a second armature tooth. The armature is moveable with respect to the stator over a predetermined stroke. A coil is associated with one of the stator and the armature for conducting an electric current and generating magnetic flux that is guided by the stator and the armature. The stator or the armature acts as a ferromagnetic core for the coil. There is a first air-gap between the first stator tooth and the first armature tooth that has a first length, and a second air-gap between the second stator tooth and the second armature tooth that has a second length. The first and second lengths are constant to within a predetermined margin over the predetermined stroke when the first and second armature teeth overlap the first and second stator teeth respectively.

  • Publication number: 20220118112
    Abstract: Lipid-based vesicles, typically herein called transfection competent vesicles (TCVs), configured to safely and efficiently deliver DNA, RNA, other nucleic acid and protein cargoes into target cells. The safety and efficiency are each, and both, achieved in part by eliminating organic solvents such as ethanol and detergents such as sodium dodecyl sulfate from the TCV loading processes (i.e., inserting a cargo into the TCV), TCV storage processes, and/or TCV delivery processes. The cargoes can also comprise nucleic acids complexed with a protein, such as a ribonucleoprotein (RNP). The systems, compositions, devices and methods, etc., herein, in some embodiments, can provide empty TCVs that can if desired be loaded at the bench without use of specialized equipment.
