Programmable DNA can be the tool that revolutionizes computing and nano-machinery.

"Researchers have developed a new, fast, and rewritable method for DNA computing that promises smaller, more powerful computers." (ScitechDaily, Beyond Silicon: How DNA Is Powering Next-Gen Computers)

"This method mimics the sequential and simultaneous gene expression in living organisms and incorporates programmable DNA circuits with logic gates. The improved process places DNA on a solid glass surface, enhancing efficiency and reducing the need for manual transfers, culminating in a 90-minute reaction time in a single tube."

"DNA carries the instructions for life, guiding everything from physical traits like hair color to disease susceptibility. Its ability to store vast amounts of information and perform complex biological processes has inspired scientists to explore DNA-based computers. These futuristic devices could be faster and more compact than today’s silicon-based computers. In a new study published today (December 11) in ACS Central Science, researchers unveiled a new DNA computing method that is both fast and rewritable — much like modern digital computers."

DNA can replace the silicone in the next generation of computers. The programmed DNA circuits can make fundamental things in the miniaturized technology. The ability to reorder the DNA makes it possible to create cells that can input data to computers in the form of electric impulses. 

The programmable DNA circuit can turn the cell to operate as a robot. Or it can make small machines act like cells. The miniaturized robots can be the tool. 

That makes fundamental things in cancer treatment and many other things. The problem is how to make those robots close and select the cancer cells and release their chemicals or start to destroy the internal structures of the cancer cells. 

The nanomachine can destroy mitochondria from the cancer cell. Or it can cut the protein wires. That makes immune cells' shells low voltage and denies their ion pump operation. The thing is that the nanorobots blur the line between living organisms and robots. 

Nanotechnology is an extremely good tool for medical purposes. Or it would be an extremely good tool. If it can be fully controlled. The nanomachine can be the cell that cannot create descendants or divide. The cell can be the bacteria that creates enzymes that destroy the cancer cells. The nanomachine can be the long protein that travels into the targeted cells and fills them. 

Or it can be one cell from a cell group that cannot divide. That cell can created from cloned cells.  The cell can have a programmed suicide gene and when it slips into the cell group there it is cloned. That cell can die. That thing pulls all of those cells into the low-voltage that touches the cell. There are many ways to destroy wanted cells. But the problem is always how to make nanomachines to search and destroy only wanted cells. If nanorobots go out of control it causes dangerous situations in the human body.
