Nanorobots in Medicine Aziz Daabash Brett Michalk Amanda Mogollon Derek Nelson
What are Nanorobotics ? 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.
Applications • Treating arteriosclerosis • Fighting cancer • Helping the body clot • Parasite Removal • Gout "the disease of kings" • Breaking up kidney stones • Cleaning wounds http://www.youtube.com/watch?v=P7zw9fvfBZI
Motivation • The Problem: • Diabetes Patients must take small blood samples many times a day (uncomfortable and inconvenient). • The need for constant glucose monitoring.
Motivation • The solution: • Painless • Reduces patients time spent suffering from hyperglycemia • Monitor glucose at different locations • Determine damage to specific tissue • “Onboard sensors”

Nanorobot Architecture How should the nanorobot be designed? Integrated Circuit SIMPLICITY!
Nanorobot Architecture What materials should be used? • CNTs in CMOS used as a nanobiosensor • Relaxed SiGe • Reduce self-heating • Improves performance
Nanorobot Architecture How will it be powered?
Nanorobot Architecture How will the data be transmitted? -Acoustic -Light
Nanorobot Safety Will nanorobots react in our body? Choose a proper membrane polymer material to prevent the action of enzymes.
Nanorobot Safety How will you get the nanorobots out of your body? Enzymes inside the nanorobot can be released once a signal has been sent.
Advantages • 3 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.
Conclusions • Use 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 Research • More 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 Submitted by U1
Positive Aspects • Well organized • Included an outline of the presentation • Followed outline • Slides titles matched outline • Informative • How they work • Applications
Negative Aspects • Text size • Too small on some slides • Some slides are too busy • Too much text/too small • Should split into several slides • References • Should show when background information stops and paper review begins
Possible further discussion • More info on how nanorobots operate/move • Show pictures of actual nanorobots instead of artists’ renditions • Choose one particular nanorobot to explain in detail in addition to the generalities provided.

Group U3 Review Nanorobots in Medicine
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
Nanorobots in Medicine • Review of Team U4 by Team U5 – • Jaynesh Shah • Greg Pudewell, • Edwin L. Youmsi Pete • John Pack.
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-Robots Presented 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
