How Nanorobots Work ?

Imagine going to the doctor to get treatment for a persistent fever. Instead of giving you a pill or a shot, the doctor refers you to a special medical team which implants a tiny robot into your bloodstream. The robot detects the cause of your fever, travels to the appropriate system and provides a dose of medication directly to the infected area.

Surprisingly, we're not that far off from seeing devices like this actually used in medical procedures.

What are Nanorobotics ?

Applications•Treating arteriosclerosis•Fighting cancer•Helping the body clot•Parasite Removal•Gout "the disease of kings"•Breaking up kidney stones•Cleaning wounds

MotivationThe Problem:

•Diabetes Patients must take small blood samples many times a day (uncomfortable and inconvenient).

•The need for constant glucose monitoring.

MotivationThe solution:

•Painless

•Reduces patients time spent suffering from hyperglycemia

•Monitor glucose at different locations

•Determine damage to specific tissue

•“Onboard sensors”

Nanorobot SafetyWill nanorobots react in our body?

Choose a proper membrane polymer material to prevent the action of enzymes.

Nanorobot SafetyHow will you get the nanorobots out of your

body?

Enzymes inside the nanorobot can be released once a signal has been sent.

Advantages3 samples of blood daily vs. once every 90

days

Reliability

Comfort

Results

• Simulated environment : 36 C , pH of 7.4• BGLs are transferred every 2 hours• Biosensor achieved 90% of steady state signal in 90 ms• Every 2 hours sensor is activated for 2 minutes.

ConclusionsUse of nanorobots in the medical field is more precise

and efficient than conventional medical practices

Nanorobots enable a more effective diabetes treatment

3-D simulators can be used as nanomechatronic systems that provide physical and numerical information for nanorobot task-based modeling

Medical nanorobots may be buildable 10-20 years from today using an advanced molecular manufacturing technology

Further ResearchMore functions should be included in the

nanorobot.

Consider how the electrical impulse in our body will affect the electrical components of the nanorobot.

Make technology accessible to the public (optimize cost)

• Effective areas :– The presentation was well organized and Informative.– Interesting topic that has a huge potential in the medical field.– Showing appropriate YouTube videos, nice and innovative use of graphics.– Oral presentation and eye contact.– Both presenters looked professional and dressed up.– Speakers were knowledgeable of subject and had done a good amount of research on the topic.– Innovative discussion of further research (ie. Use of iphone for energy supply)

• Our answers to the following comments:– How nanorobots operate/move (further discussion)

This was mentions on slides 14 and 15.– Showing pictures of actual nanorobots instead of computer generated ones

Nanorobots do not exist yet , current research is only based on theory and computer simulations.– Choose one particular nanorobot

our presentation specifically explained medical nanorobots for drug delivery.– References and pictures citations are missing:

references were shown at the end of the presentation, as for the picture citation, the wrong slides were update to the class website.

– Outline of the presentation is missing.we have orally mentioned the outline of the presentation at the beginning of the lecture.

– Didn’t mention nanorobot safety and future applications.nanorobot safety was discussed , refer to slide 16. nanorobots ARE future applications that haven't been produced yet.

– Improve transitions flow.after the first speaker finished his section he proceeded to shif the presentation to the next presenter by introducing their name and what will they be talking about.

– What types of nanorobots are proposed and what are their potential uses for each type?as mentioned in the presentation , the proposed nanorobots were propsed to be used as drug delivery method, as for their specific technical type, the research paper did not mention any information related to this.

– Are there any methods in fabricating/manufacturing these nanorobots suggested?the researched paper had no information on how these nanorobots fabricated/manufactured.

– I would like to know more about the relaxed SiGe integration into the nanorobot fabrication.details about the relaxed SiGe integration into the nanorobot fabrication was not mentioned in the researched paper. But further information can be found at the following link: http://www.nanorobotdesign.com/papers/cancer.pdf page 2

– Are the nanorobots actively activated or passively activated? How can these robots do their functions if they are coated in an enzyme that will nullify the activation of antibodies in the bloodstream? Will it somehow open up the cover and work on the parts of the body? Is that any potential harm in the body?we have mentioned in class that these robots use enzyme reaction to target specific tissue or cells of the body to deliver the drug , specific amino acid sequance will trigger the activation of these nanorobots. Potential harm of these nanorobots was mentioned in the slides, refer to slides 16 and 17.

• Areas of improvement:– Text size was too small on some slides and some slides were too busy.– References– inconsistent font size and style.– Some hesitation at the beginning of the presentation.

Review of U4 presentationNanorobots

Positive AspectsWell organized

Included an outline of the presentationFollowed outlineSlides titles matched outline

InformativeHow they workApplications

Negative AspectsText size

Too small on some slidesSome slides are too busy

Too much text/too smallShould split into several slides

ReferencesShould show when background information

stops and paper review begins

Possible further discussionMore info on how nanorobots operate/moveShow pictures of actual nanorobots instead of

artists’ renditionsChoose one particular nanorobot to explain in

detail in addition to the generalities provided.

Review of Group U4’s Presentation-

The presenters did really well at:

Showing appropriate YouTube videos Nice and innovative use of

graphics Explaining the content of the slides

Oral presentation was very thorough

Making eye contact with the audience

The presenters could improve at:

Making similar slides more consistent- Titles and text were different sizes Different formats: paragraph,

bullets... Cite all pictures and graphics Outline in beginning of presentation-

What will you talk about? In what order will you talk about it?

Parts of presentation felt out of order

Perhaps discuss nanorobot safety and architecture after finishing the results and conclusion of article

Discuss additional future applications

Group U3 Review

Technical Review

Great attention getter (first slide) 3d visualization pictures were very

helpful Some of the font could have been

enlarged Further research section could have

been more detailed Explain a few of the pictures more

thoroughly

Oral Presentation

Very educational and informative presentation

Great eye contact Both presenters looked professional

and dressed up Could improve on making transitions

flow a little smoother

Oral and Quality of Slides Review Speakers did a good

job in the oral aspect of the presentation. They were loud and clear confident. Implying they had done a good amount of research on the topic.

The slides clear, visible and not overcrowded. Team U4 made good use of several pictures, images and graphs.

Technical Review

The presentation was satisfying from a technical standpoint

We would have liked them to discuss the use of nanorobots in conjunction with the iPhone or other electronic devices more

NANO-ROBOTSPresented by: Group U4

Critiqued by: Group U6

CRITIQUE: ORAL PRESENTATION & SLIDES

Slides were very easy to read good background and font color

The use of illustrations complimented the text

Figures were relevant to the topic on the slide, and helped convey key points

Speakers had good voice projection to the back of the room

Speakers did well in maintaining eye contact most of the time However, there was a little hesitation in

giving the lecture – maybe more practice would help

CRITIQUE – TECHNICAL CONTENT

Excellent topic – will be relevant for millions of people worldwide

Research paper was based on theoretical simulations only – further research needs to be done to increase the functionality of the nano-robots

Introduction and explanation of research paper was excellent, and presented in a way which was very easy to understand

We personally thought that the use of cell phones to charge the robots and receive information from the robots was very innovative
