An instrument developed at Boston University (BU) could advance fundamental knowledge in the field of neuroscience and lead to treatments for neurological diseases. The tapered fiber optoacoustic emitter (TFOE) uses the optoacoustic effect to enable neuromodulation with single-cell precision. It provides high spatial resolution for ultrasound stimulation, generating an ultrasound field with a spatial precision of 39.6 µm. It also enables optoacoustic activation of single neurons and subcellular structures.
To advance spatial resolution and optoacoustic conversion efficiency, the research team, led by professors Chen Yang and Ji-Xin Cheng, used a new approach to fiber engineering and a new deposition method to build TFOE….READ MORE
