Biochips are miniaturized labs that can perform many biochemical reactions simultaneously. They allow researchers to quickly screen large numbers of samples to detect diseases or bioterrorism agents. Biochips contain microarrays on a chip that can analyze molecules to identify gene sequences, pollutants, or other biochemical constituents. While initially developed in 1983, biochip technology has expanded and various types of biochips are now used for applications like individual identification, health monitoring, and replacing documents like passports.
2. In molecular biology, biochips are essentially
miniaturized laboratories that can perform
hundreds or thousands of simultaneous
biochemical reactions
Biochips enable researchers to quickly screen
large numbers of biological analytes for a
variety of purposes, from disease diagnosis to
detection of biotrrorism agents.

4. Biochip is a microprocessor chip, an outcome
of computer science ,electronics and biology
It is collection of microarray arranged on a
solid substratum and permit many test
Used to analyze molecules associated with
living organisms
Help in identifying gene
sequences,environmental pllutants,air toxins
and other biochemical constituent
5. HISTORY
Developed in 1983 for monitoring fisheries
Large scale biochip development in 1990
The major biochip companies are A.V.I.D AND
TROVAN IDENTIFICATION SYSTEM
Today ,a large variety of biochip technologies are
either in development or commercialized
In 1980 fred sanger and walter gilbert were
awarded the nobel prize for DNA sequencing
In 1983 kary mullis awarded nobel prize for PCR
reaction
6. It is a microcomputer chip insrted under skin
dermis for identification purpose
Biochip system is a radio frequency
identification system (RFID) use low
frequency radio signals to communicate
betweeen biochip and reader
7. IMPLANT SYSTEM OF BIOCHIP
Implant system of biochip consist two
components
The transponder
The reader or scanner
8.
9.
10. TRANSPONDER
Two types – Passive or Active
Biochip system is a radio frequency
identification system (RFID) use low frequency
radio signals to communicate betweeen biochip
and reader
The transponder consist 4 parts:
Computer micro chip
Antenna coil
Tuning capacitor
Glass capsule
11. Computer microchip-the micro chip store a
unique identification number from 10 to 15 digit
long
Antenna coil-this ,tiny primitive radio antenna
receives and send the signals from reader or
scanner
Tuning capacitor-the capacitor is charged by the
small signal send by the reader
Glass capsule-”houses” the microchip,antenna
coil and capacitor.It is made of biocompactabile
material such as soda lime glass
12. READER OR SCANNER
Consist of an excitor coil which create an
electro magnetic field
Provide energy to activate the implanted chip
Also carries a receiving coil to receive the ID
number
Contains the software and components to
decode the receive code and display the
result in an LCD display
13. WORKING
reader transmit a low power radio signals and
activate the implanted biochip
ID number transmitted by the transponder
and the received by the reader
Reader displays the ID number on the readers
LCD display
14. BIOCHIP IMPLANT
Injected by a hypodermic syringe beneath the
skin
Injection is safe and simple
Anesthesia is not required
Usually injected beneath the neck of dogs
and cats
15.
16. APPLICATION
With a biochip tracing of a person or animal
anywhere in the world is possible
A biochip can store and update financial,
medical,demographic data,basically everything
about a person
Biochip are potent in replacing passport,cash
,medical records
Medicinal implementation of biochip as-glucose
detector,as oxygen sensor,as blood pressure
sensor
17. ADVANTAGES
to rescue the sick
To find the lost people
To identify people uniquley
To monitor the health condition of individuals in
which they are specially employed
Perform thousands of biological reactions in a
few seconds
Incrase the sppd of diagnose the unknown
pathogens
18. DISADVANTAGE
They rise critical issue of personal privacy
They mark the freedom of human freedom
and dignity
Turning every men,womem and child in to a
controlled slave
They can be implanted into ones body
without their knowledge
19. FUTURE
A chip implanted somewhere in human
bodies might serve as a combination of credit
card,passport,driving license,personal diary.
No longer would it be needed to worry about
losing the credit cards while travelling
