Abstract: The present technology relates generally to receiving arrays to measure a characteristic of an acoustic beam and associated systems and methods. The receiving arrays can include elongated elements having at least one dimension, such as a length, that is larger than a width of an emitted acoustic beam and another dimension, such as a width, that is smaller than half of a characteristic wavelength of an ultrasound wave. The elongated elements can be configured to capture waveform measurements of the beam based on a characteristic of the emitted acoustic beam as the acoustic beam crosses a plane of the array, such as a transverse plane. The methods include measuring at least one characteristic of an ultrasound source using an array-based acoustic holography system and defining a measured hologram at the array surface based, at least in part, on the waveform measurements. The measured hologram can be processed to reconstruct a characteristic of the ultrasound source.

Abstract: Nano-actuators having a helical member formed with a ferromagnetic shape memory alloy (FSMA) are disclosed that are elastically deformable between a compressed state and an expanded state by the application of a magnetic field. The nano-actuators may include a ferromagnetic head portion, that may be formed from the FSMA or from another material.

The nano-actuators are magnetically propelled to the target cells, and oscillated and/or rotated to mechanically damage the target cells to induce apoptosis. The nano-actuators may be formed by electro deposition of the FSMA into a nano-helical template.

Abstract: A polymerizable unit that yields an electrochemically responsive polymer (advantageously pyrrole) is anchored by polymerization within a polycaprolactone matrix to form an electroactive scaffold upon which cells can be cultured and in which the micro- and nano-topological features of the polycaprolactone matrix are preserved. A scaffold manufactured in accordance with the preferred embodiment can support Schwann cells, which produce nerve growth factor when electrically stimulated. Nerve growth factor has been demonstrated to promote the regeneration of nerve tissue. By implanting the scaffold on which Schwann cells have been cultured into damaged nerve tissue and applying a voltage across the scaffold, nerve growth factor is produced, thereby promoting repair of the damaged nerve tissue.
