    Abstract: Firstly, a custom designed 3D printer with x-y-z gantry robot with an accuracy of 0.1 μm was adapted with a custom designed printing head (51b). Secondly, a two component silicone elastomer suitable for RP was developed that incorporates the desired characteristics and properties similar to those commercially available for the provision of facial and body prostheses. The silicone elastomer is composed of polydimethylsiloxane (PDMS) chains, filler, catalyst and crosslinker. By varying the amount of these components the mechanical properties of the silicone elastomer can be altered, for example, tensile strength, tear strength, hardness and wettability. To achieve these desired properties consideration must also be given to the set time and viscosity of the silicone elastomer and additionally the speed at which the material is printed.

    Abstract: According to one embodiment, a person's own RBCs can be recruited as secondary bioscavenger carriers in vivo using a nanopolymer-BChE complex, with an affinity ligand (antibody or peptide) for selective targeting to the RBCs and a cell-penetrating peptide for uptake into the RBCs. A general approach according to an embodiment involves parenteral administration of the nanodevice to gain access to the systemic circulation, which then seeks out and attaches to the person's RBCs, followed by transport into the RBCs (to minimize clearance from the circulation), leading to long-term circulation of the bioscavenger enzymes and thus protection against intoxication.
