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.

Abstract: The present disclosure describes a method for targeted delivery of permanently-acting or temporarily-acting neurotoxins, neurosuppressants, or other compounds having a neurologic effect to specific locations of the heart, including for example, but not limited to, nodes of the cardiac autonomic nervous system such as the atrial ganglionated plexi (GP). Chemical ablation of the atrial GP as described herein via magnetically-targeted magnetically-susceptible nanoparticles can effectively suppress GP activity and atrial fibrillation related, thereto without permanent damage to either myocardium or intrinsic CANS.
