Acupuncture needles combined with nanotechnology was recognized as the world's first application of this technology.

‘The porous acupuncture needles offer enhanced therapeutic properties by applying nanotechnology on the acupuncture needles for the first time in the world.’

The findings of this experiment, which was conducted in
collaboration with DGIST's research team and the Addiction Control
Research Center at Daegu Haany University, have attracted the attention
of the relevant academic field in light of the fact that the experiment
combined nanotechnology with acupuncture needles.




Professor In's research team developed PANs with fine pores ranging in sizes from nanometers (nm= one billionth of a meter) to micrometers (? = one millionth of a meter) on the surface of the needles using a nano-electrochemical method.
PANs are formed by anodization, and are characterized by a widened surface of the needles through the following process: anion (F-) contained in the electrolyte bored into the surface of the metal needles (positive) and created fine and uniform pores.
PANs are expected to be as effective as conventional large and long needles by minimizing the sense of pain during acupuncture treatment while expanding the surface area of the needle 20 times greater than conventional acupuncture ones.
Through electrophysiological experiments with rats, In's research team proved that PANs excel in transferring signals from a spinal dorsal horn by the in vivo stimulation of Shenmen (HT7) points, and in particular, demonstrated that the efficacy of PANs is superior to conventional acupuncture needles in treating alcohol and cocaine addiction in animal experiments.

Professor Su-Il In from DGIST's Department of Energy Systems Engineering said, "The development of nanotechnology has taken science and technology to the next level in various fields such as solar cells, quantum computers, display development, and the like. Based on this experiment's achievement of combining nanotechnology and oriental medicine, I will continue to conduct research in order to be at the forefront of the scientific population of oriental medicine."
