Development and clinical approval of biodegradeble magnesium alloy

KIST made magnesium alloy from essential minerals to human body

This biodegradable and bioabsorbable metal decomposes from 6 months to 2 years after being transplanted into human body and hence, medical devices made with these materials are expected to reshape the landscape in the field of fracture treatment, as it reminders second operation to take out the device after patient recovery obsolete.

KIST Consortium Consortium participated by U & I (Co.), ASAN Medical Center and Seoul National University (led by Dr. Seok, Hyun-kwang of KIST Biomedical Research Institute) succeeded in developing high strength/low biodegradable metal made from basic elements and minerals essential to human body.

The Consortium also developed biodegradable and bioabsorbable medical devices for use in orthopedics & plastic surgery while earning approval to clinically test the device. The clinical trial is currently in progress conducted by Ajou University Medical Center.

The heart of the research is matching potentials between the matrix structure of metal and the secondary agents on the matrix structure to overcome the fundamental limitation of metal materials, which is speedy degradation. Using this application, new innovative materials can be developed such as metal alloy with the 2nd and 3rd additional elements while still maintaining the electrochemical nature of pure metal. The remarkable achievement was made possible thanks to the Computational Materials Science Laboratory at Kookmin University (led by Professor Cha Phil-ryung), which helped to create the effects of synergy between computer simulation and technology.

With extensive support of the Seoul Strategic Industry Initiative, the key support program of the Seoul City government for Smaller enterprises' R&D, KIST Consortium has succeeded in developing new degradable metal materials inside human body after transplant, and also received approval to clinically test these metals from the Korea Ministry of Food and Drug Safety as a bioabsorbable fixation device to be used in orthopedics and plastic surgery.

KIST was selected as a beneficiary for the Seoul Strategic Industry Support Initiative in 2010 and has been working on the project for 3 years. Further, these findings were published in the 2013 August edition of Scientific Report, a sister magazine of the world-renowned scientific journal, Nature.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
