Abstract: Provided herein are methods of quantifying extracellular vesicle concentration, such as exosomes, by measuring cholesterol content in a sample. Also provided are methods of processing extracellular vesicles to remove non-exosomal species which contain cholesterol.

Abstract: Novel robust electroactive polymers (EAPs) and EAP-based systems are described, which contract and expand at low voltages to provide for a shape-morphing system, which also sense mechanical pressure, from gentle touch to high impact, and which attenuate force. These EAPs and EAP-based systems can be used in a prosthetic liner, and potentially as the entire prosthetic liner, in a prosthetic hard socket, in shoe wear, sports gear, protective gear, and military gear, and in compression equipment, to contract and expand in strategic areas as needed to maintain a perfect fit, to sense pressure and provide feedback to automatically maintain perfect fit, and to attenuate force for an extremely comfortable fit.

Abstract: Systems, methods, and compositions for removing organophosphate toxins from blood are disclosed herein. The compositions include a lipid-based capture particle that displays BChE that binds to the toxin. The methods include acoustically separating toxins bound to lipid-based capture particles from blood factors of whole blood.
