3. INTRODUCTION
o Identifies us uniquely.
o Size–uncooked grain of rice.
o Can be used to track our local. Fig: Biochip
o Injected under the skin using syringe.
o Respond to signal from detector.
o Daniel Man holds the patent for a chip that
can be tracked by satellite.
4. Definition of biochip
Collection of micro arrays arranged on a
solid substrate.
Can perform thousand of biological
operation.
Human Genome Project.
Increased speed of identification of gene.
Also used in toxicological, protein
&biochemical research.
6. Structure And Working
Two parts- Transponder & Reader or
Scanner.
Transponder:
• Uses RFID system.
• Not harmful to
human body. Fig: Component of Biochip
• Actual biochip implant.
• Four parts: Microchip, Antenna Coil,
Capacitor & Glass Capsule.
8. Microchips:
• Stores unique identification number, 10-15
digit.
• ID number etched to surface.
• Cannot be altered.
• AVID stores 70 trillion unique numbers.
• Electronic circuitary transmit ID number to
reader
9. Antenna Coil:
• Copper around ferrite or iron core.
• Simple , tiny, primitive.
• Receives and sends signals from the reader
or scanner.
Tuning Capacitor:
• Stores small electrical charges(<1/1000 of
a watt)
• Tuned to same frequency as reader.
10. Glass Capsule:
• Houses all components.
• Made of biocompatible material.
• Polypropylene sheath.
• Injected using hypodermic syringe.
Fig: Biochip & Syringe
11. Reader or Scanner
• Exciter coil provides energy activate chip.
• Receiving coil receives data.
• Displayed in LCD.
• All done in milliseconds.
Working :
• Enables biochip. Fig: Reader & Scanner
• Receiver amplifies code.
• Generates low power electromagnetic field.
• Data displayed.
12. Development and Working
Brain ON-OFF Switch
• Turn around brain signal.
• Primarliy interfere with
abberate brain function.
• Uses high frequency electric
purpose.
• Active implant –
Medtronics Inc., US.

13. Adding Sound to life
• Cochlear implant.
• Mimics the job of hair cell.
• Splits incoming noises
into a number to channels.
• Succesful cochlear implant
• “Clarian & Nucleus”.
Fig: Adding Sound to life
14. DNA Biochips
• Gene probe based.
• Matched box sized.
• No radioactive labels.
• Reduces disposal cost.
• Distinguish b/w bacteria,
virus,chemical or biological
species. Fig: DNA Biochip
• Tuan Vo-Dinhn-at DOE of ORNL.
• Less blood, no sacrifice on accuracy.
15. Advantages
• Small in size.
• Faster & Powerful.
• Detect miltiple viral agent in parallel.
• Aids deaf ,dumb,blind.
• Stores personnal data.
• Ease of use.
• Human tracking etc…
16. Future
• A chip implanted some where in human body
might serve as a combination of
1.Credit card
2.Driving license
3.Passport
4.Personal identification etc…
• No longer would it be needed to worry
about losing all above thing.
