What is a Biochip? Components of Biochip In what way they work? Advantages of Biochips. Disadvantages of Biochips. Future of Biochips.
IntroductionIntroduction
Biochips invented 9 years ago by gene scientist Stephen Fodor.
Collection of miniaturized test sites of living entities (microarrays) 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.
In BriefIn 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 computers.

Components Of BiochipComponents Of Biochip
Computer Chip: Stores the unique ID number
Components Of BiochipComponents Of Biochip
Tuning Capacitor: Charged by the small (1/1000 of Watt) signal sent by the reader
Components Of BiochipComponents Of Biochip
Antenna Coil: Primitive Radio antenna to receive and send signals
Components Of BiochipComponents Of Biochip
Glass Capsule: Made of biocompatible material such as soda lime glass, hermetically (air-tight) sealed, covered with Polypropylene polymer
In What Way They In What Way They Work?Work?
Transmits a small signal
Charges the tuning capacitor
ID number transmitted by the transponder
This number is then compared with a database listing of registered pets.
ImplantImplant
Injected by a Hypodermic syringe beneath the skin
Usually behind the neck in cats and dogs
Advantages Of BiochipsAdvantages Of Biochips
TO RESCUE THE SICK. TO FIND LOST PEOPLE. TO IDENTIFY PERSON UNIQUELY. IN MONITORING HEALTH CONDITION OF INDIVIDUALS IN WHICH THEY ARE SPECIFICALLY EMPLOYED. THEY CAN PERFORM THOUSANDS OF BIOLOGICAL REACTIONS ,OPERATIONS IN FEW SECONDS.
Disadvantages Of Disadvantages Of BiochipsBiochips
THEY RAISE CRITICAL ISSUES OF PERSONAL PRIVACY.
THEY MARK THE END OF HUMAN FREEDOM AND DIGNITY.
THEY MAY NOT BE SUPPORTED BY LARGE % OF PEOPLE.
THERE IS A DANGER OF TURNING EVERY MAN, WOMEN, AND CHILD INTO A CONTROLLED SLAVE.
THEY CAN BE IMPLANTED INTO ONES BODY WITHOUT THEIR KNOWLEDGE.
Future Of BiochipsFuture Of Biochips
If people feel that they loose their privacy because of Biochips, they may resist use of it. But if they feel that it could help in a lot of ways like detecting , monitoring and curing of diseases they can use them intensively. So it is users of chip who determine its future .
