Nanotechnology can be defined as the science and engineering involved in the
design, synthesis, characterization, and application of materials and devices whose smallest
functional organization, in at least one dimension, is on the nanometer scale or one billionth of
a meter, and the promise that nanotechnology brings is multifaceted, not only offering
improvements to the current techniques but also providing entirely new tools and capabilities.
Nanotechnology, it has become an increasingly promising area of research and development
which has the potential to revolutionize medical sciences.
Current research of Nano medicine focuses on its uses as drug delivery devices, through the
utilization of buckminsterfullerene, which we term as Nano robots.
Nano robot is a term used to describe future microscopic robots that could have a wide range of uses.
Nanotechnology as a science has evolved from notions and speculation to emerge as a prominent
combination of science and engineering, which stands to impact innumerable aspects of technology.
Such a prudential work has been coined in the field of medicine esp. in neuro surgery. Nanorobots
using molecular nanotechnology (MNT) is going to change the future and offer possible future
technologies for Neuro sciences & Neuro engineering.
Various Nano techniques will make substantial contributions to the advancement of
neurosurgery in the near future, such as :
(1) Nano manipulation,
(2) Nano imaging,
(3) Non-surgical Nano repair and
Nano robots are injectors, containing a yellow liquid that they can inject using their needle tip. They could be treating
a brain disease. The Nano robots use propellers to move in the surrounding liquid. The nerve cells have a central cell
body (that can be as large as 0.1 millimeters across), with thin threads (axons and dendrites) forming the connections
of the neural network.
Used for target drug delivery
Advanced nanorobots will keep all
human body cells in perfect
repair, preventing disease and aging.
• these systems are built from single atoms or
molecules assembled chemically.
• these nanostructures are created from splitting
down larger systems to its base elements.
Three things that must occur in parallel for nanotechnology applications in neurology and neurosurgery to come
to fruition are:
advances in chemistry and materials science that produce ever more sophisticated synthetic
and characterization approaches
advances in the molecular biology, neurophysiology, and neuropathology of the nervous system
the design and integration of specific nanoengineered applications to the nervous
system, which take advantage of the first two points.
Cell repair by nanorobot using MNT
Illustrated here is a cell repair robot called a chromallocyte. After
the chromallocyte (in upper half of picture) locates and docks with
the cell nucleus (in lower half of picture), it extends a tool-tipped
robotic arm into the nucleoplasm. The job of this nanorobot is to
replace old damaged chromosomes with new ones in every cell.
Psychiatry will have to develop new ways of understanding the cyborgian mind. Psychopharmaceuticals
are being developed now to try to control cognitive and affective traits, and it is likely that BCIs will be
able to have similar effects. We already see the beginning of that process with the use of deep brain
stimulation for psychiatric disorders. The ability to access the brain, to understand its inner workings, to
connect it to external devices, promises remarkable resources to aid the infirm as well as worrisome
opportunities to cause harm. It is important to develop these technologies with a careful eye towards
using them responsibly.
Nanorobot’s sensor identification
Nanotechnology has proven to great potential for providing neurotherapeutic modalities to limit
and reverse the neuropathology by supporting and promoting functional regeneration of
damaged neurons, providing neuroprotection, and facilitating the delivery of neuroactives such
as drugs, genes and cells across boundaries.
Hope in better future, these technologies could create a drastic change in human life and life
style and it can be possible to treat and cure deadly diseases like cancer, tumor, psychological
problems, cell repair, non-bleeding surgeries etc
