A novel technique developed by researchers that have an edge over the conventional surgery which involves detailing through incisions.
The conventional surgery involves cutting and stitching while reshaping nose or ears, thereby resulting in permanent scars and marks. Thus, a team of researchers developed a molecular surgery which involves using small needles, molds printed through 3D technology and electric current to reshape the tissues leaving no marks and scars. The researchers envisage this novel technique as an affordable process which can be conducted under anesthesia within five minutes. The results of this initiative were presented at the American Chemical Society (ACS) Spring 2019 National Meeting & Exposition.
Brian Wong, M.D., Ph.D., who is at the University of California tried suing infrared laser which would heat up the cartilage to reshape the tissue however, the method proved to be quite expensive and resulted in killing of tissue in case heated strongly thus, he suggested to pass current to heat the cartilage tissue. However, the team observed that even though the tissue was reshaped it was not due to heating but due the electrolysis of water by the current in the cartilage tissue. The water molecules are converted into ions and protons of hydrogen and oxygen. The negatively charged proteins present in the cartilage cancels out with the positive charge of the protons, making the tissues malleable.
This novel technique was tested on rabbit ears which stand upright suing 3D printed mold to obtain the desired shape. If the research team had not applied electric current to the mold and simply removed it then the ears would stand upright again. However, inserting tiny needles and then passing current helped reshaping the tissues without causing damage. Currently, the researchers are trying to obtain license for the initiative and exploring applications.
