: Nano engineers at the University of California, San Diego, have developed a new technology that can make micro-3D in a few seconds (3D)
The structure of a soft, bio-compatible gel.
In the near future, the technology may produce better systems for growing and studying cells in the laboratory, including stem cells. Long-
Semester, the goal is to be able to print the biological tissue of regenerative medicine.
In the future, for example, doctors may replace the damage caused by heart disease with tissue rolled off the printer.
Biological processing technology called dynamic optical projection stereo forming (DOPsL)
It was developed by Professor Chen Shaochen in the nano-engineering laboratory.
Current manufacturing technologies such as photography and micro-
Contact printing is limited to generating simple geometry or 2D patterns.
Stereo printing is known for its ability to print large objects such as tools and auto parts.
Chen said, the difference is in Micro
Print the nano-resolution required to mimic natural fine tissue
Details, including blood vessels, are critical for the distribution of nutrients and oxygen throughout the body.
For example, if there is no ability to print the vascular system, engineering the liver or kidney is useless in regenerative medicine.
With DOPsL, Chen\'s team was able to achieve more complex geometric shapes such as flowers, spiral and hemisphere.
Other current 3D production technologies such as double
It can take several hours to make a 3D part.
Biotechnology uses computer projection systems and precisely controlled micromirrors to glow on selected areas of solution containing photos
Sensitive biological polymers and cells. This photo-
A layer of solid structure is formed at one time during the induction solidification process, but in a continuous manner.
This technology is part of a new biological processing technology developed by Chen under four technologiesyear, 1.
A $5 million grant from the National Institutes of Health.
Focusing on manufacturing nano-biological materials and nano-photons for biomedical engineering applications, Chen research team recently entered a new structure and material engineering building, which will bring nano-and structural engineers, medical equipment laboratories and visual artists work together under one roof.
Details of the technology have been published in the journal Advanced Materials. (ANI)
