INTRODUCTION
 Symbiosis between electronics and
  biology/medicine
In Brief

 Bio + Chip = Biochip
   Bio: stands for any biological entity eg:
    protein, DNA
   Chip: a computer chip
   Biochip: a mate between biological entity
    and a computer
In Brief

 Collection of miniaturized test sites of
  living entities (micro arrays) arranged
  on a solid substrate that permits
  many tests to be performed at the
  same time in order to achieve higher
  throughput, speed, accuracy and
  smaller size
Types of Biochips
                 Biochip

      Function             Position

Interaction   Capture   Implantable   External
BIOCHIP PLATFORM
 Requires micro array technology, transduction
  and signal processing technologies to output
  the results of sensing experiments
Basic Principle
 The biochip consists of “probes” (DNA,RNA)represented
  by a point on a support (chip). These “probes” bind very
  specifically the “targets” present in the biological
  samples to test.
Fabrication Problem
Transponder
 The implantable biochip
 Passive Biochip: No Batteries
 Composed of
     Microchip
     Antenna coil
     Tuning capacitor
      Glass Capsule
Transponder
 Computer Chip: Stores the unique ID
  number
Transponder
 Antenna Coil: Primitive Radio antenna
  to receive and send signals
 Tuning Capacitor: Charged by the
  small (1/1000 of Watt) signal sent by
  the reader
 Glass Capsule: Made of biocompatible
  material such as soda lime glass,
  hermetically (air-tight) sealed,
  covered with Polypropylene polymer
Implant
 Injected by a Hypodermic syringe beneath the
  skin
 Usually behind the neck in cats and dogs
Reader/Scanner
 Transmits a small signal
 Charges the tuning capacitor
 ID number transmitted by the transponder
APPLICATIONS
 Tracking and identification devices in animals
  around 1983 for monitoring fishery
 Now widely used in monitoring pets and
  animals in zoos
 Implanted under the skin of the animal with a
  unique ID number
 A biochip can store and update financial,
  medical, demographic data, basically
  everything about a person
APPLICATIONS
 Biochip as Glucose Detector

 Biochip as an Blood Pressure sensor

 Biochips really are potent in replacing
  passports, cash, and medical records
CONCLUSION
 A chip implanted somewhere in human bodies might
  serve as a combination of credit card, passport,
  driver's license, personal diary. No longer would it be
  needed to worry about losing the credit cards while
  traveling. A chip inserted into human bodies might
  also give us extra mental power. The really
  fascinating idea is under fast track research "but
  we're close.”

 The day in which we have chips embedded in our
  skins is not too far from now. "This is science fiction
  stuff." ”This is a true example to prove science really
  starts with fiction”.
