A research team with KAIST Professor Jeong, Jae-Woong in South Korea have developed a non-reusable intravenous needle that changes from hard to soft when inserted into the body, increasing its affinity for biological tissues.
This injection needle is made of gallium, a type of liquid metal. This allows the needle to be softened by the body’s temperature, which allows the injection site to move freely when injecting the drug and prevents needle damage to the blood vessel wall.
In particular, needles that have been used once are said to remain soft at room temperature, eliminating needlestick injuries and reuse issues.
KAIST (Korea Advanced Institute of Science and Technology) is a public institution under the Ministry of Science and ICT of South Korea. KAIST was established in 1971 as Korea’s first research-oriented graduate school of science and technology, with the government’s goal of economic development through science and technology.
The government enacted a special law for the establishment and operation of the institute, establishing it as an educational institution under the Ministry of Science and Technology with state-of-the-art equipment, educational support for outstanding faculty and students, and special exemptions for military service.
