Abstract: A concentric tube steerable device includes a plurality of tubes having a nested, concentric configuration. The tubes include an outer tube and an inner tube that extends coaxially within the outer tube. The inner tube terminates at a tip, and a pose of the tip is effectuated through individual or collective rotation or translation of the tubes about a tube axis. The concentric tube steerable device includes an actuator for rotating at least one tube about a respective tube axis, and a translator for translating at least one tube along a respective tube axis. Each tube includes a precurved portion and a corresponding axis of precurvature. For at least one tube, a flexural rigidity of the tube along its axis of precurvature is less than a flexural rigidity of the tube along a second axis that is perpendicular to the axis of precurvature, thereby improving stability of the tube.

Abstract: Amphiphilic co-polymer lipid particle has a core comprising a chlorophyll pigment-protein complex or a bacteriochlorophyll pigment-protein complex within an annulus of membrane lipids, and an outermost layer of amphiphilic co-polymer surrounding an outermost surface of the membrane lipids. Such lipid particles are made by isolating photosynthetic membrane to form isolated photosynthetic membrane, adjusting the chlorophyll concentration of the isolated photosynthetic membrane, and solubilizing the isolated photosynthetic membranes in an amphiphilic co-polymer for a preselected time period that allows amphiphilic co-polymer lipid particles to form. The amphiphilic co-polymer lipid particles form a layer between a cathode and an anode in a photo-electrical energy generating device, and methods of making the same, including a layer of detergent micelles encapsulating lipid proteins rather than amphiphilic co-polymer lipid particles.
