PRESENTATION ON NANOROBOTICS

DEFINITIONS:

DEFINITIONS Nanorobots would constitute any “smart” structure capable of actuation, sensing, signaling , information processing, intelligence, and swarm behavior at nanoscale . • Bionanotechnology and nanobiotechnology are terms that refer to the intersection of nanotechnology and biology . Given that the subject is one that has only emerged very recently, bionanotechnology and nanobiotechnology serve as blanket terms for various related technologies .

INTRODUCTION:

INTRODUCTION Nanorobotics - an emerging technology field of creating machines or robots whose components are at or close to the microscopic scale of a nanometer (10−9 meters). The names nanobots , nanoids , nanites , nanomachines or nanomites can also be used. Nanomachines are largely in the research-and-development phase

MORE ON INTRODUCTION:

MORE ON INTRODUCTION Nanotechnology robots - quintessential NEMS ( nanoelectromechanical systems) sensing, actuation, control, communications, power, and interfacing across spatial scales and between organic and inorganic materials can be done. their size, comparable to biological cell. nanorobots have a vast array of potential appplications in fields such as environmental monitoring or medicine.

HISTORY OF NANOROBOTICS:

HISTORY OF NANOROBOTICS The history of the nanorobotics as an integrated circuit for medicine is highlighted as an advanced CMOS nanoelectronics device. It utilizes implementation of advanced biomedical instrumentation with remarkable improvement to common clinical practice.

MORE ON HISTORY:

MORE ON HISTORY Basis and sorce of information-International technology indexes and science rankings such as ISI Web of Science ( Thomson Reuters ), Scopus , Engineering Village , and PubMed (NIH National Institute of Health, U.S. National Library of Medicine) First Development The first scanning probe microscope (SPM) was the scanning tunneling microscope (STM), invented in the early 1980s by Binnig and Rohrer at the IBM Zurich laboratory, for which they won a Nobel prize .

Future Developments:

Future Developments Scientists hope to create nanorobots which would be self-assembling, with the possibility that they would communicate chemically. According to Aristides A. G. Requicha of the Laboratory for Molecular Robotics, "Complex tasks are likely to require a group of nanorobots working cooperatively. This raises interesting issues of control, communications, and programming of robot 'societies.'"

INVENTOR OF NANOROBOT:

INVENTOR OF NANOROBOT Adriano Cavalcanti Known as nanorobot pioneer . Cavalcanti is the medical nanorobotics inventor for the pratical hardware architecture of nanorobots ,. His structure used in environmental monitoring , brain aneurysm , diabetes , cancer and cardiology .

Slide 10:

His advanced prototype provided a suitable integrated circuit approach, using an effective wireless platform for energy supply with cell phones and satellite, to enable the commercial implementation of nanorobots with long distance teleoperation and data transfer for health care , drug delivery , and laparoscopic nanosurgery .

NANOROBOTICS THEORY:

NANOROBOTICS THEORY Since nanorobots would be microscopic in size. it requires very large numbers of them to work together to perform microscopic and macroscopic tasks. These nanorobot swarms, both those incapable of replication (as in utility fog ) and those capable of unconstrained replication in the natural environment.

Nanorobot for Brain Aneurysm:

Nanorobot for Brain Aneurysm The idea of nanorobots floating throughout our arteries to fight diseases and deliver drugs is migrating from science fiction to medical fact. the team chose a nano -integrated circuit version that uses hybrid materials, photonics, and wireless communication for manufacturing and control.

HOW DOES THIS STUFF WORK:

HOW DOES THIS STUFF WORK The robot in this illustration swims through the arteries and veins using a pair of tail appendages.

Slide 15:

doctor need to give a treatment in the form a special medical team which implants a tiny robot into your bloodstream . The robot detects the cause of your illness, travels to the appropriate system. then provides a dose of medication directly to the infected area

APPROACHES:

APPROACHES 1-) BIOCHIPS Its the joint use of nanoelectronics , photolithography , and new biomaterials It provides a possible approach to manufacturing nanorobots for common medical applications, such as for surgical instrumentation, diagnosis and drug delivery. This method is currently in use in the electronics industry.

Slide 17:

2-) Nubots Nubot - abbreviation for "nucleic acid robots". Nubots are synthetic robotics devices at the nanoscale . Representative nubots include the several DNA walkers reported by Nadrian Seeman's group at NYU, Niles Pierce's group at Caltech, John Reif's group at Duke University, Chengde Mao's group at Purdue, and Andrew Turberfield 's group at the University of Oxford.

:

Bacteria based This approach proposes the use of biological microorganisms, like the bacterium Escherichia coli . [21] this model uses a flagellum for propulsion purposes. The use of electromagnetic fields are normally applied to control the motion of this kind of biological integrated device, but has limited applications.

Nanomedicine:

Nanomedicine Nanorobots can be used for several medical approaches a-)drug delivery It refers to the presence of drug molecules where they are needed in the body and where they will do the most good. This can potentially be achieved by molecular targeting by nanoengineered devices. lipid- or polymer-based nanoparticles

Slide 21:

The small size of nanoparticles endows them with properties that can be very useful in oncology , particularly in imaging. Quantum dots ( nanoparticles with quantum confinement properties, such as size- tunable light emission), when used in conjunction with MRI (magnetic resonance imaging), can produce exceptional images of tumor sites.

C-)surgery:

C-)surgery A research has been conducted at Rice University, nanoshells has been used to weld two chicken pieces.

d-)Visualization:

d-)Visualization scientists used to dye the cells. These dyes needed to be excited by light of a certain wavelength in order for them to light up. These tags are quantum dots attached to proteins that penetrate cell membranes.

e-)Neuro-electronic interfaces:

e-) Neuro -electronic interfaces neuro -electronic interfacing is a visionary goal dealing with the construction of nanodevices that will permit computers to be joined and linked to the nervous system The computers will be able to interpret, register, and respond to signals the body gives off when it feels sensations.

nanonetwork:

nanonetwork A nanonetwork or nanoscale network is a set of interconnected nanomachines . It are to perform v ery simple tasks such as computing , datastoring , sensing and actuation . [

Communication approaches:

Communication approaches A-) Electromagnetic This is defined as the transmission and reception of electromagnetic radiation from components based on novel nanomaterials . Recent advancements in carbon and molecular electronics have opened the door to a new generation of electronic nanoscale components such as nanobatteries .

B-) Molecular:

B-) Molecular Molecular communication is defined as the transmission and reception of information by means of molecules .

Nanorobot Race:

Nanorobot Race In the same ways that technology development had the space race and nuclear arms race , a race for nanorobots is occurring. Hewlett-Packard and Northrop Grumman have been recently working in the development and research of nanorobots .
