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.
