How to Fabricate Biocompatible 3D Microstructures in Seconds?

Best Financial Markets Analysis ArticleNano-engineers at the University of California, San Diego, have developed and demonstrated a novel and highly innovative technology that can fabricate three dimensional (3D) micro-structures out of soft, biocompatible hydrogels in a matter of seconds. The Chen Research Group -- spearheaded by nano-engineering professor Shaochen Chen -- is bringing nano and structural engineers, medical device labs and visual artists into a collaborative environment under one roof to pioneer a 21st century renaissance in next generation technology. The synthetic fabrication of complex natural structures like spirals, flowers and hemispheres, has now been demonstrated via this new technology.


Printing 3D Blood Vessels in Seconds out of Biocompatible Hydrogels!

Regenerative Medicine: Repairing Damage caused by Heart Attacks and Replacing Organs by Printing Them

1. The goal of many biomedical researchers is to find a way to grow new tissues or even organs for those patients who need them. To do that, the cells involved need to have a structure they can grow on, like plants growing on a cage or trellis.

2. Near term, the 3D microstructures technology which is now being pioneered, could lead to better systems for growing and studying cells, including stem cells, in the laboratory.

3. Medium term, the goal is to be able to print smaller biological tissue patches for regenerative medicine. For example, in the future, doctors may be able to repair the damage caused by heart attacks by replacing damaged tissues with newly printed biocompatible synthetic tissue.

4. In the long term scientists hope to see this new technology, or indeed an evolution of this technology, used to actually print complete tissues and organs, ready for implanting into patients.

5. The key future goal in the development of this innovative technique is for humankind finally to acquire the capability of biological tissue and organ printing for use in full fledged regenerative medicine and advanced body repair. This could extend the average life span of human beings by decades.

Quantum Jump in Speed of Fabrication

The key benefit of this brand new technology is the ability to print microstructures in a few seconds whereas up until now other three-dimensional fabrication techniques -- like two-photon photo-polymerisation -- used to take hours to fabricate a similar structure. This type of new technology has already been the subject of science fiction: many "replicants" have been fabricated instantaneously via "3D replicators" using advanced laser controlled technology. Are we almost there?

Significance of Biocompatible 3D Micro-Manufacture

Why is this new bio-fabrication technique "Dynamic Optical Projection stereo Lithography" or DOPsL so significant? The immediate application of this technique lies in the growth and study of the cells of living organisms, especially stem cells in laboratories. DOPsL has three main advantages over photolithography and micro-contact printing, the two main techniques currently used to build microstructures:

1. Operates with high resolution which is needed when trying to mimic fine details found in nature, such as blood vessels;

2. Creates complex 3D structures, instead of the simpler 2D patterns the other methods are mostly limited to; and

3. Fabricates faster than other methods to produce 3D micro-structures.

How does DOPsL work?

The bio-fabrication technique called "DOPsL" uses a computer projection system and precisely controlled micro-mirrors to shine light on a selected area of a solution containing photo-sensitive biopolymers and cells. This photo-induced solidification process forms one layer of solid structure at a time, but in a continuous fashion, like a 3D printer.

Existing Fabrication via Printing

Micro-contact printing and photolithography are existing fabrication techniques which can only produce two-dimensional structures and simple geometries. Another technique that can print three-dimensional structures called stereo lithography is best suited for large objects such as car parts and tools. The new DOPsL technology leap-frogs all these existing solutions both in terms of refinement of 3D resolution at a micro-scale and speed-of-delivery of manufacture or fabrication via high speed printing!

Conclusion

Nano-engineering specialist Chen Research Group has essentially demonstrated the capability of printing three-dimensional blood vessels and tissue in mere seconds out of soft, biocompatible hydrogels. Being able to print blood vessels within tissue is essential to achieving the promise of regenerative medicine because this is how the body distributes oxygen and nutrients. An engineered biomaterial without the blood vessels is not of much use to a living organism including human beings.

Asymmetric Threats Contingency Alliance (ATCA) & The Philanthropia

We welcome your participation in this Socratic dialogue. Please access by clicking here.

ATCA: The Asymmetric Threats Contingency Alliance is a philanthropic expert initiative founded in 2001 to resolve complex global challenges through collective Socratic dialogue and joint executive action to build a wisdom based global economy. Adhering to the doctrine of non-violence, ATCA addresses asymmetric threats and social opportunities arising from climate chaos and the environment; radical poverty and microfinance; geo-politics and energy; organised crime & extremism; advanced technologies -- bio, info, nano, robo & AI; demographic skews and resource shortages; pandemics; financial systems and systemic risk; as well as transhumanism and ethics. Present membership of ATCA is by invitation only and has over 5,000 distinguished members from over 120 countries: including 1,000 Parliamentarians; 1,500 Chairmen and CEOs of corporations; 1,000 Heads of NGOs; 750 Directors at Academic Centres of Excellence; 500 Inventors and Original thinkers; as well as 250 Editors-in-Chief of major media.

The Philanthropia, founded in 2005, brings together over 1,000 leading individual and private philanthropists, family offices, foundations, private banks, non-governmental organisations and specialist advisors to address complex global challenges such as countering climate chaos, reducing radical poverty and developing global leadership for the younger generation through the appliance of science and technology, leveraging acumen and finance, as well as encouraging collaboration with a strong commitment to ethics. Philanthropia emphasises multi-faith spiritual values: introspection, healthy living and ecology. Philanthropia Targets: Countering climate chaos and carbon neutrality; Eliminating radical poverty -- through micro-credit schemes, empowerment of women and more responsible capitalism; Leadership for the Younger Generation; and Corporate and social responsibility.
