A group of researchers at the Korea Advanced Institute of Science and Technology (KAIST) has developed a highly customizable neural stimulation method. The technology that can print the heat pattern on a micron scale to enable the control of biological activities remotely.
The researchers have integrated a precision inkjet printing technology with bio-functional thermoplasmonic nanoparticles to achieve a selective nanophotothermal neural stimulation method.
Using printed gold nanorod particles in a few tens of microns resolution over a several centimeters area, the researchers showed that highly complex heat patterns can be precisely formed upon light illumination according to the printing image. The research team expects that this will serve as an enabling technology for personalized precision neuromodulation therapy for patients with neurological disorders.
