May Be Able to Target Tumors, Spare Healthy Tissue," by Michelle Castilo.
The DNA nanorobot
emulates this level of specificity through the use of modular components in which different hinges and molecular messages can be switched in and out of the underlying delivery system, much as different engines and tires can be placed on the same chassis.
In 2012 Wyss Institute researchers reported in Science that they had built a nanorobot
that uses logic to detect a target cell, then reveals an antibody that activates a "suicide switch" in leukemia or lymphoma cells.
3 ( ANI ): Researchers have taken a major step towards building the first nanorobot
that would facilitate targeted transport of medications to the diseased cells in the body for faster and more beneficial effect.
This vision of a bionic nanorobot
called NANO-Copter is made of a carbon nano-tube, which forms the main body with flexible limbs that are used to move and manipulate objects, and a biomolecular motor located on the head with a propeller of Ni.
It's a DNA nanorobot
, a primitive version of the machines that may someday perform tasks too small for humans to do.
Nanomedicine applications include treating cancer and infectious disease, understanding and influencing the aging process, enhancing human intelligence, and sending tiny nanorobot
surgeons into a person's body to operate without producing scars.
But, Joy's anxiety is aroused by the next step he envisions after the introduction of nanorobot
devices, that of making self-assembling nanorobots
--that is, nanorobots
that replicate of their own accord, without human intervention, and possibly contrary to human desires (2).
After all, we're not close to building a nanorobot
, and perhaps it can't be done.
Therefore the main problems in nanorobotic control are: (i) design of relevant dynamical model of nanorobot
motion, (ii) create of the related control algorithm and (iii) measurement at the nanoscale.
Like a regular robot, a nanorobot
may be made of many thousands of mechanical parts such as bearings and gears composed of strong diamond-like material.
Although they say the ideal nanomanufacturing environment would enable a human teleoperator to experience even the sounds and smells of the ultra-Lilliputian operations, the Japanese researchers have set their sights for now on a "nanorobot
system," which would enable workers to see and feel what the nanorobot
is doing on submicron scales.
