    Neuromodulation plays an important role in deciphering neural circuits and exploring clinical treatments for neurological diseases


    The photoacoustic process involves the conversion of light pulses into sound waves at ultrasonic frequencies


    A Boston University research team has recently begun using photoacoustics for high-precision neuromodulation


    Photoacoustic neuromodulation can be achieved by a variety of techniques


    Some of the novel optoacoustic techniques studied in the primers include fiber-based neural stimulation, biocompatible films, and nanoparticle mediation


    Highly miniaturized fiber-based photoacoustic transmitters can deliver drugs to cell membranes or be integrated into medical devices such as catheters and needles to provide real-time surgical guidance


    Complementary to fiber-based photoacoustic emission devices, biocompatible photoacoustic membranes can serve as new neural interfaces that provide a variety of functions, from photoacoustic stimulation to structural support and growth guidance


    The prospects are enticing, but there is still work to be done
