Combining Living Cells and Nonliving Materials for New Technologies

Category: Science & Technology
Posted: 02:09PM

As technology gets smaller and smaller, new possibilities open up and new challenges arise. Among these challenges is how to build technology with almost unbelievably small components. Researchers at MIT have found an answer to that, which could lead to some very interesting applications as well.

Working with nanoscale materials is difficult when you are as large as a human, but it is not so hard for bacteria. E. coli is a well understood bacterium that researchers have been experimenting with for some time now, and the MIT researchers have found a way to use its ability to produce biofilms to build useful structures. By manipulating the peptides on the fibers in the biofilm, it is possible to have them pick up non-living materials, including gold nanoparticles, which could form gold nanowires within the biofilm. The researchers also manipulated programmed the bacteria to be able to respond to signals from others, so multiple bacteria could work together to build a specific structure.

This research was inspired by natural examples of living and non-living materials being combined, such as bones. It could lead to new means of building materials from the bottom up as well as useful applications like scaffolds for tissue engineering.

IMAGINE A SCIENTIST or genetic engineer in a lab who by using intelligent planning and design makes an entire living cell, including its DNA, from scratch in a laboratory. This cell reproduces into billions of more cells. After a hundred years, someone discovers this cell and thinks that it is nothing more than an accident of nature. That it originated by chance and was not ultimately a product of any intelligence or design. Doesn’t that sound like atheists on this site? In reality scientists have never created life. Even if they do, it won’t be by chance. What scientists have done through intelligent design and planning is genetically modify already existing forms of life through genetic engineering. By modifying already existing forms of life scientists have been able to produce new forms of life, but they did not produce these new life forms from non-living matter. In every case of modern genetic engineering scientists have had to use already existing forms of life or their parts. But, again, if scientists do produce a living cell from scratch, it won’t be by chance but by intelligent design. So, such a feat would never support any theory of a chance origin of life. Recently, a scientist did use intelligent design and planning in building DNA from scratch and then planting it in an already living cell. Natural laws can explain how an airplane or living cell works, but it's irrational to believe that mere undirected natural laws can bring about an airplane or a cell. Once you have a complete and living cell then the genetic program and biological machinery exist to direct the formation of more cells, but how could the cell have originated naturally when no directing code and mechanisms existed in nature? All of the founders of modern science believed in God. Read my Internet article: HOW FORENSIC SCIENCE REFUTES ATHEISM Sincerely, Babu G. Ranganathan* (B.A. theology/biology) Author of popular Internet article, TRADITIONAL DOCTRINE OF HELL EVOLVED FROM GREEK ROOTS * I have had the privilege of being recognized in the 24th edition of Marquis "Who's Who In The East" for my writings on religion and science, and I have given successful lectures (with question and answer time afterwards) defending creation from science before evolutionist science faculty and students at various colleges and universities.
